Making Room for a New Guess

by Joe Cerniglia


"The problem is not what might be wrong, but what might be substituted precisely in place of it....You make a hole for a new guess."[1] - Richard Feynman


Robert Ballard and crew members of the Expedition Vessel Nautilus have concluded their mission to Nikumaroro. From August 9 to August 21, 2019, Ballard and his team scanned the ocean floor adjacent to Nikumaroro for signs of large pieces of Amelia Earhart’s plane. The Nautilus’ search area was more extensive than any search of the island’s deep water margins to date, reaching, at times, a distance more than a mile from shore. However, no Electra, fragmentary or otherwise, was found. In related work, a team supervised by Fred Hiebert, archaeologist-in-residence for National Geographic, searched human bone collections held by the Te Umwanibong Museum and Cultural Centre in Tarawa, Kiribati and found a fragmentary skull. Although details of the provenance of this skull are lacking, members of the team believe it may be the same skull that was discovered in 1940 on Nikumaroro and sent on to Fiji for analysis in 1941. If the skull, retrieved from Tarawa and now undergoing analysis in Florida, yields DNA that can be matched with that of relatives of Amelia Earhart, Ballard has promised to return to the island to resume the underwater search for Earhart’s vanished Electra 10e.

And if the skull does not display a clear biological link to Amelia Earhart, then, since the airplane has also not been found, must the Nikumaroro hypothesis finally and irrevocably now be said to have been disproven?


Many bloggers and screenwriters have already sharpened their pencils and begun to write that it has.


Those who wanted the Earhart mystery solved had pinned their hopes on a large piece of the Electra peering through the murky depths at the camera lights of Argus and Hercules, the remotely operated vehicles of the Nautilus. The failure to find the Electra, however, should not invite hasty conclusions.


The missing airplane may, however, be an opportunity to reexamine what we think we know or what we suppose must be true in order for the Nikumaroro hypothesis to be correct.




The Possibilities
Again, pieces of aircraft wreckage were neither seen nor suggested in all of the underwater imaging conducted by Ballard and his team. Assuming that this probing was effective, and that post-processing of recorded images and data does not reveal new evidence of the airplane, one must ask what would be the reasons why no airplane was found. I can see six possibilities:

1) Pieces of the Electra are not underwater because the Electra was never at Nikumaroro. (Other elements of the hypothesis for Nikumaroro, however, would in that case continue to defy a unifyingly plausible explanation.[2])

2) Pieces of the Electra are underwater in areas that have been explored, but they are too encrusted with coral and ocean silt or other deposits to be noticed.

3) Pieces of the Electra are underwater but are hiding in shoreward areas not explored by divers and too shallow for exploration by autonomous and remotely-operated vehicles.

4) Pieces of the Electra are underwater but the plane floated many miles offshore and sank into abyssal depths.[3] (The farther one searches from shore, however, the more difficult it becomes to demonstrate that the Electra, if found, ever actually reached Nikumaroro.)

5) Pieces of the Electra are underwater but have by now been pulverized into smaller pieces that are not large enough to be noticed [4], wherever they may lie, or they appear insignificant when compared with other nearby identifiable objects such as S.S. Norwich City debris.

6) Pieces of the Electra were underwater in shallow areas close to land but have been gradually washing up onto the shoreline, driven by wind and storms, with little of it visible today.

There may be other possibilities, but these appear to be the most likely ones. Other than the null hypothesis (#1), which excludes all the others, more than one of these possibilities could overlap; that is, some could jointly be true.

"And the question is what to throw away and what to keep. If you throw it all away, it's going a little far, and you don't get much to work with." [5] - Richard Feynman



Guessing Toward Land
Members of TIGHAR (The International Group for Historic Aircraft Recovery) have often pondered the sixth possibility: that the airplane sank in very shallow water, close to the shore but just deep enough to be at most times invisible. In the high-energy environment close to the island’s fringing coral reef, cyclones and lesser storms striking frequently during the winter months would do it great damage. All or most of the wreckage could have been swept shoreward, in stages, slowly, piecemeal, but inexorably, over the ensuing decades. Perhaps some of the smaller pieces are even now washing ashore.[6]

Anecdotal accounts, over a long time frame, lend some support to this conjecture.

  • Emily Sikuli, who lived on the island from 1939 to 1941, stated she saw a large piece of an airplane on the northern shore of Nikumaroro near the wreck of the S.S. Norwich City. In an interview, when asked how large the airplane was, Emily stated, holding her arms out, "About four arm spans."[7]
  • Pulekai Songivalu, who lived on the island after World War II as resident schoolmaster, stated, "I saw pieces of airplane in the lagoon."[8]
  • Tapania Taiki, daughter of Pulekai Songivalu, who lived on the island from 1958 or 1959 and left in the mid 1960s, stated, "I saw a piece of airplane wing on the reef."[9]
  • Between 1944 and 1945, John Park Mims (1920-2018) made many trips to Nikumaroro in a PBY from Canton to resupply the Coast Guard LORAN station stationed on the island. He stated that he witnessed a large fish having been recently caught by the islanders. The hook in the fish's mouth was, according to the islanders, made from aluminum from a downed airplane. The line leader was aircraft control cable, recognizable to Mims and to his friend, Eyvind Wahlgren, as from a type of aircraft that was smaller than a PBY.[10]
The sixth possibility, aircraft wreckage washing up on shore, is the one most consistent with anecdotal accounts, but anecdotal accounts are of limited value, because memories can change, be inaccurate or otherwise wrong. It is noteworthy, however, that the native anecdotes tend to corroborate one another and are supported by some members of the Coast Guard who visited the island as well.

There is a discarded bit of evidence, additionally, that seems as though it might be consistent with the sixth possibility, and with the anecdotal accounts. It consists of a photo, named the “wreck photo.”


The Wreck Photo, Reconsidered
The photo was in the possession of U.S. Navy Captain George Carrington. Carrington said the photo was given to him by a former British seaman who had served on the HMS Adamant. For reasons of privacy, the seaman requested anonymity. This seaman claimed that, sometime in 1946 or 1947, he and other men from the ship had gone ashore on what they took to be a deserted Pacific island, whose name escaped his recollection, for purposes of recreation and gathering sand for boiler room fires. While in back of the tree line, the sailor took the photograph of the wreck of a twin-engined airplane. Carrington brought the photo in the late 1980s to the notice of Lockheed Aircraft Corporation, which enlisted the help of the Smithsonian Air and Space Museum, and later TIGHAR, in learning more about its origins and possible significance to the mystery of Amelia Earhart’s disappearance.[11]

TIGHAR, after more than 21 years of exhaustively researching the photo, ultimately dismissed it in 2009 as a depiction of the wreckage of a Japanese Tachikawa Ki-54 on Agrighan Island. It based its identification of where the photo had been taken on the logs of the HMS Adamant, whose only recorded port of call on an island seeming to match Carrington's description in 1946-47 had been Agrighan. It based the identification of the airplane in the photo on the way the engine cowlings had come apart, which were different from how an Electra’s engine should have, and on what it claimed was the presence of a “small round inspection plate” just forward and a little rightward of the center line from the windshield, on the nose section of a surviving Tachikawa Ki-54s housed in the Beijing Aviation Museum. Both the airplane in the wreck photo and the airplane in the Beijing Aviation Museum, it claimed, carried this same inspection plate in identical locations.[12] What TIGHAR claims to be an inspection plate in photos, however, seems difficult to distinguish from what may actually be a small hole, nor is it apparent from its research that all Tachikawa Ki-54s carried an identical inspection plate, nor even that the oval-shaped spot on the photo of the Tachikawa K-54 in Beijing is an inspection plate.




Odd Attributes of the Wreck Photo
Regardless of where the photo was taken or what airplane it shows, there is something very unusual about the condition of the airplane depicted. The propeller in the aircraft engine shown is apparently unbent. When a propeller-driven aircraft crashes, either through “controlled flight into terrain” or through a loss of control in an attempted landing, propellers will be a primary area of damage. Most always they are bent. How the propellers bend can be an indication of what the airplane was doing prior to the crash. If a blade is bent forward, it indicates the airplane engine was operating at high power at the time of impact. If a blade is bent rearward, it indicates the engine was supplying little or no power, but the blades were still turning.[13]

Indeed, the Electra itself had its propellers turned significantly forward when it crashed in March, 1937 at Luke Field in Hawaii, thus indicating the engines were under full power at the time the propellers impacted the runway.[14]

A Tachikawa Ki-54 recovered from Lake Towada in Japan has its propellers turned significantly rearward.[15]


Propeller of wrecked Tachikawa Ki-54 has propeller bent rearward.

From the relatively pristine condition of the propeller blades in the wreck photo, we may infer that the significant damage sustained by this airplane, including most of the fuselage and cockpit having been ripped away from the engine, was not caused by a crash. Rather, the damage was caused subsequent to a landing.

Perhaps the damage was caused on land by a storm, or, perhaps it was caused by the airplane having been heaved up violently to the place where it was found, just inshore from the beach, by an ocean swell. Another possibility is that the airplane was fired upon in an air assault. This could also explain how it could be so severely damaged and yet escape damage to its propeller.

However, if the airplane in the photo was not attacked, it would seem that for it to sustain this kind of damage, without damage to the propellers, it must have been landed successfully and been abandoned by or lost from the control of its owner. If such an abandonment or loss of control occurred, this would seem to have been a very unusual event, highly atypical of most aircraft incidents or crashes. It is, however, exactly the scenario envisioned by TIGHAR for Earhart’s Electra.




Of Propellers and Their Hubs: Was the Airplane in the Photo a Tachikawa Ki-54?
Both the Earhart Electra 10e and the Tachikawa Ki-54 used variable pitch, constant-speed, non-feathering propellers. The propellers on these two airplanes, however, have one very noticeable difference. Most photos of the Tachikawa show large propeller hubs covering the area in which the blades meet.[16] The Earhart Electra 10e had no such massive propeller hub. The airplane in the wreck photo also has no such large propeller hub. Photos of wrecks of the Tachikawa show that these hubs can survive a crash, and should have remained mounted, if originally present, on the propellers in the wreck photo.










Photos of different models of the Japanese Tachikawa Ki-54 with propeller hubs in place.





This photo of a wrecked Tachikawa Ki-54 shows one propeller hub is present and one is missing. The port engine has lost its propellers and its propeller hub. Both engines show significant compression damage around the cowling, indicative of violent impacts. The surviving propeller blades on the starboard engine are bent. [17]




This photo of the Electra 10e shows no propeller hub.

All of this is not to imply that the wreck photo cannot possibly depict a Tachikawa Ki-54, or that it does depict an Electra 10e. What this re-analysis does imply, however, is that circumspection about the identity of the airplane in the photo is warranted.



Sick Trees: Could the Photo Have Been Taken on Nikumaroro?
While it would be impossible to know with certainty on which Pacific island the photo was taken, there would seem to be nothing about the photo that rules it out as having been taken on Nikumaroro. In fact, there is historical information about the colony on Nikumaroro that correlates very well with the photo itself.

Most noticeable in the background of the wreck photo are the presence of several tattered and wasting coconut trees. Only a year after the photo was said to have been taken, several telegrams to the District Officer on Canton Island express concern regarding the condition of the coconut trees on Nikumaroro. These telegrams suggest ways of coping with the difficulty, including burning Buka groves in order to rid these areas of substances “poisonous for coconuts.”[18]




The problem of maintaining the health of the coconut trees on Nikumaroro appears to have been a perennial concern up until the time the colony was abandoned. As late as 1963, the Pacific Islands Monthly related how drought conditions had killed off many of the coconut trees of the colony, resulting in the necessity of the colony’s abandonment.[19]

Was the Photo Taken on Agrighan?
In contrast to the difficulty of keeping the coconut palms disease-free on Nikumaroro, Agrighan Island appears during the 1940s to have thrived with healthy vegetation. Commander McAfee, in his report from the search for the lost crewman of a B-29 that crashed there, described a place that was seemingly ideal for agriculture, of all types:

"Agrighan Island, although of volcanic origin, is covered for the most part by rich, black, loamy soil conducive to a heavy growth of vegetation and plant life. It is true that the greater portion of the coastline and a large section of the eastern half of the island is made up of sharp, jagged, lava rock in the form of caves, ledges and cliffs. But excluding these portions of the island, most any kind of vegetables or fruits could be produced to maintain many times the number of natives found there. There are areas on the southwestern, southern and southeastern part of the island that could easily be turned into pasture land for the maintenance of live stock (sic)."[20]

No mention is made in McAfee’s report of the types of problems with dying coconut trees that appear to have very much troubled the Nikumaroro colony.

If the wreck photo truly depicts a Tachikawa Ki-54 that crashed on Agrighan Island, none of the three aircraft that crashed on Agrighan fit that description.

A B-29 was reported lost on the northeastern side of Agrighan on April 27, 1945 [21] and the Bureau of Aircraft Accident Archives (https://baaa-acro.com) shows two aircraft accidents during the 1950s on Agrighan, occurring within days of one another.[22] On December 17, 1953, a Consolidated PB4Y-2 Privateer, conducting weather observations on Typhoon Doris, crashed somewhere off Agrighan. Three days later, a Douglas C-47 Skytrain (DC-3) took off from Andersen AFB on Guam in search of the lost crew. At some point, the airplane lost visual reckoning of its altitude, and crashed into the volcano in the center of Agrighan Island. All crew of both airplanes were lost, as was the crew of the B-29 despite a vigorous search for one member thought to have parachuted to safety.[23]

The B-29 was a four-engine bomber whose engines powered four-bladed propellers,[24] easily distinguishable from the two-bladed propellers shown in the Wreck Photo. The Douglas C-47 Skytrain was powered by three-bladed propellers.[25] The Consolidated PB4Y-2 Privateer was also powered by three-bladed propellers.[26] None of the three recorded aircraft wrecks on Agrighan have been documented in recent archaeological surveys.[27] It is, of course, not impossible that a Tachikawa Ki-54 crashed on Agrighan during World War II and was not documented, but one must needs ask what a Japanese aircraft on wartime patrol would be doing reconnoitering an island that was of limited strategic importance and that they already controlled. In 1945, Agrighan was inhabited by about 120 natives, who farmed a coconut plantation managed by four Japanese overseers.[28]



Where is the Airplane?
If Amelia Earhart’s Electra 10e really landed on Nikumaroro, was washed out to sea, then swept shoreward, in pieces large and small over the ensuing decades, as the colonists’ anecdotes, anecdotes from the U.S. Coast Guard, and, possibly, the wreck photo, all seem to imply, one may well ask: where are those pieces today?

Even if many small Electra 10e pieces may have been collected by TIGHAR in its various expeditions to the island since 1989, and even if a large piece here and there were transported from Nikumaroro to other islands, such as to Canton in the 1970s[29], this would still leave a large portion of the airplane, presumably waiting to be discovered in the scaevola of Nikumaroro or along the beach, intact.


So far, however, no large engines or wings or cockpit have emerged from the many expeditions TIGHAR members have made to the island. No smaller pieces that were both easily and uniquely identifiable to the Electra 10e have been found.[30]




The Missing Piece
Even if all the anecdotes are true, and much of the photographic and artifactual evidence collected on Nikumaroro to date indicate an Electra 10e was once there, these cannot account for a complete Electra 10e. There is a missing piece in the puzzle, and that piece is likely to be more complex than simply a remnant of an airplane.

According to Dr. Thomas King, there is much evidence in the old colonial village on Nikumaroro of colonists having been interested in quarrying aluminum for handicrafts and tools. He writes:

“Lots of aluminum, all in small pieces, usually more or less rectangular, cut from larger pieces with tin snips or maybe a machete. Some pieces were in an area more or less between the houses—marked by the remains of a stone-lined platform—and the dense charcoal and bone deposit left by the cookhouse. With one of the aluminum pieces were pieces of pearl shell and a glass bead. It looked like someone at Manybarrels had been making handcrafts with aluminum decorations.”[31]

On the other hand, this interest seems to have been greatly tempered and restrained by a kind of superstition that anything to do with the airplane was haunted and, thus, dangerous and forbidden. Tapania Taiki, daughter of the schoolmaster on Nikumaroro, who lived on Nikumaroro from the late 1950s to the early 1960s, stated in a 1997 interview:

“The older people said they saw the skeletons of a man and a woman, one each. The elders said ‘Do not go to where the plane is, there are ghosts there.’ They were trying to scare us to keep us away from there.”[32]

It is difficult to imagine or explain the reasons behind this combined fascination with and prohibition against airplane wreckage that colonists reported having seen on the island. Nevertheless, no matter the motivations for doing so, the elder colonists appear to have processed and transmuted significant amounts of aircraft aluminum, and other pieces of equipment from some complex machinery, for their own purposes.

We see possible evidence of this transmutation in the debris of the old carpenter shop. There, the remains of an old workbench or storage cabinet is piled high with circular bearing sleeves, cables of various gauges, and metal tubes. Some of these items have been marked with orange and pink archaeological flagging tape from previous expeditions to the island.


An Entirely Speculative Observation
Could it be that the colonists had an interest in airplane wreckage that included more than simply tools and handcrafts? Quite apparently, at least a few were amply able to overcome their superstitions and fears at approaching what they saw. Were they attempting to reduce the amount of wreckage on the island in order to avoid too much disruptive inquisitiveness from outsiders as to whence this wreckage had come? If so, how much of this airplane wreckage the younger colonists reported having been warned against was reduced by the elders of the village to pieces too small to invite investigation by the island’s colonial administration or by the world beyond? Such speculation raises many questions. The passage of some 56 years since the colony was abandoned renders it unlikely that anyone now living can provide an answer that would neatly tie everything together.

We are left, however, with a few simple facts:
  • Ballard and his team searched the waters around Nikumaroro extensively to a depth of some 900 meters and to a distance more than a mile from shore. No obvious signs of an aircraft were spotted.
  • Pieces of aircraft wreckage were reported by colonists at various times near or on the northern part of the island.
  • These reports were echoed by reports from two supply personnel for the U.S. Coast Guard station on the island.
  • A British seaman reported, and took a photo of, his 1946/1947 discovery of a radial aircraft engine and other pieces of obvious aircraft wreckage on what he took to be a deserted island in the Pacific.

If these reports or even some of them actually happened on Nikumaroro, then the best and perhaps the only place to look for what small remnants of Earhart’s Electra 10e might remain is in the land areas of the island where wreckage was reported, both in the village and on Nutiran.



Whither Bound?
And the end of all our exploring
Will be to arrive where we started
And know the place for the first time.
- T.S. Eliot

In the final analysis, this essay should not be construed as an exhortation to revive old arguments, such as the one that swirled around the wreck photo 10, 20 and 30 years ago. It is highly doubtful the wreck photo can ever be definitively identified as a certain aircraft on a certain island.[33]

This essay should be construed as an exhortation to acknowledge that something different, perhaps very different, happened on the reef with the airplane than what those who have considered it have traditionally been willing to acknowledge.

That acknowledgement for some could mean an airplane that was never on Nikumaroro. But for those who still consider the evidence, the acknowledgement might productively involve investigating new approaches (water-penetrating LIDAR, for example, if such a thing has existed, or will exist), and - perhaps - revisiting some old approaches, by way of some old, discarded evidence, such as devoting some of the resources in time and money to the village and Nutiran that have up to now been poured into the ocean.

Such an effort would not be wasted. We would learn much more than we do about the life ways of a hardy and indomitable people, the colonial village denizens of Nikumaroro. In the process, we might also find an artifact, or two, that tells us more about the fate of a hardy and indomitable explorer who unwittingly may have found herself unrescued on this beautiful but forbidding place the islanders called home.

I am indebted to Pacific historian Scott Russell for providing me with the U.S. Navy's 1945 report on the Agrighan search and rescue operation for the crashed B-29. 

This paper is dedicated to the memory of Lt. Col. Northrop, USAAF, missing flyer from the B-29 that crashed on Agrighan on the morning of 27 April, 1945.

[29] Bruce Yoho stated that while visiting an island in the Phoenix Group in 1970 he spotted a single-row radial engine on its reef. He persuaded his helicopter pilot to fly the engine as a “sling load” back to his base on Canton. While other servicemen remembered the “engine in the shop” while on Canton, and were able to offer various opinions on what the model of the engine may have been, none remember recovering the engine from another island. The story lacks corroborative documentary evidence and supporting anecdotes. It is mentioned here only because it could, if true, help explain why nothing so obvious as a large radial engine has been found on Nikumaroro. It would, however, require the assembly of an intricate timeline or rationale to explain why, if the engine was from Nikumaroro, no colonists reported seeing such a thing, either. The story does, however, eerily correlate with the 1946-47 wreck photo, which depicts a single radial engine, and which also leaves unanswered the question of why such an engine, if from Nikumaroro, went unreported.

Lost Norwich City Crewmen: Potential Sources of the Human Remains Discovered on Gardner Island (now Nikumaroro Island) in 1940

By Kenton Spading

Earhart-Noonan Researcher

Photo by Jane Powell


Tom King's Preface: NIBBLING AT NIKUMARORO’S NULL HYPOTHESIS
As used in statistics, a “null hypothesis” is the proposition that there’s no relationship between two variables. In the more forgiving vernacular of the social sciences and humanities, the term is often used to mean simply that the hypothesis we’re testing is not correct. Since we hypothesize that Amelia Earhart and Fred Noonan landed and died on Nikumaroro, the null hypothesis is that they didn’t.

A fundamental part of the scientific method is to determine with as much rigor as possible whether the null hypothesis is correct. Ideally – and however little fun it may be – one should try very hard to find evidence that confirms the null hypothesis. If you can’t find it, then with a degree of confidence you can reject the null hypothesis and say that, yes, in all probability your preferred hypothesis is correct.

In the paper that follows, Kenton Spading explores a body of historical evidence that may support the Nikumaroro null hypothesis with reference to the human bones and artifacts reportedly found there in 1940. In simple terms, Spading asks himself, and the data: “If the null hypothesis is correct, and the bones and artifacts do not represent Earhart or Noonan, whose were they?”

An important possibility is offered by the missing crewmen of the SS Norwich City, most of them Yemeni, lost on Nikumaroro’s northwest shore (Nutiran) in 1929. The Norwich City wreck site is about four miles away from the site where the 1940 bones and artifacts were found, at the opposite end of the island, but at least two ways to account for this spring readily to mind:

1. A crew member, thrown off the exploding freighter or abandoning ship, is swept by the storm through Tatiman Passage into the lagoon, and down to its far southeast end. Perhaps he’s unconscious, or disoriented, but if so he comes to and staggers inland, up to the crest of the surge ridge we now call the Seven Site, and there expires – perhaps after living for a time on the local fish, birds, and turtles. His body is then dismembered and its bones scattered by crabs, rats, and birds.

2. A disaffected crew member takes advantage of the opportunity afforded by the shipwreck to get ashore and hightail it. Avoiding detection by his shipmates, he walks to the far end of the island and camps, lying low while the other survivors are rescued. Belatedly realizing that the island lacks water, he eventually succumbs, and is taken apart by the local fauna.

I feel another novel coming on.

I don’t personally much like the Nikumaroro null hypothesis. It’s messy, and it doesn’t easily account for much of our Seven Site archaeological evidence – the compact, the zipper pull, the freckle crème jar, and so on. Our working hypothesis that the Seven Site represents Earhart’s campsite is more elegant than the null; it doesn’t require us to challenge the immortal words of William of Occam, that “plurality should not be posited without necessity” (Occam's razor). But, as physicist Richard Muller has recently noted in a very different context: “Occam’s razor is often a poor guide to truth” (Muller 2016:140).

I think Kenton Spading has done us all a service by gathering and organizing a plethora of data bearing on the Nikumaroro null hypothesis, on which we can productively chew for quite some time. -TFK

For a variety of reasons summarized elsewhere (TIGHAR.org, King 2012, 2018, Jantz 2018, Gillespie 2018) these bones are suspected to be those of Amelia Earhart.

The purpose of this paper is to compile and summarize the available data pertaining to the 1940 discovery, with reference to a possible source of the bones other than Earhart – the crewmen lost when the SS Norwich City grounded and exploded on the island’s northwest reef in 1929.

The 1940 Bones Discovery
Nikumaroro, then known as Gardner Island or Kemin’s Island, was inhabited in the 1890s during an effort by John T. Arundel to operate a coconut plantation there. When the Norwich City ran aground in November 1929, however, the island had been uninhabited since approximately the mid-1890s. It remained uninhabited until December 1938.
   
From October 13 to October 15, 1937, a British Western Pacific High Commission (WPHC) party explored the island with the intent of assessing its suitability for colonization as a component of the Phoenix Island Settlement Scheme (PISS). One of the colonial officers involved in this assessment visit, Eric Bevington, wrote in his journal that he saw “signs of previous habitation.” In 1992 he stated that it looked “like someone had bivouacked” (camped) on the island.[1] His colleague Harry Maude opined that this site represented debris left by Arundel’s workers.[2]

On December 20, 1938, a second WPHC expedition, which included Mr. Maude and Cadet Officer Gerald Gallagher dropped off the first Gilbertese [3] colonists on the island (a ten-man working party under government contract). On December 22, Maude and Gallagher departed to deposit workers on other islands in the Phoenix Group. The Nikumaroro (aka Gardner) colonists began preparing a village and coconut plantation.

In April 1940, while clearing land, the colonists discovered a human cranium and buried it. In early September 1940 Gallagher returned to Nikumaroro to set up his headquarters as the WPHC Acting Officer in Charge of the PISS. The colonists informed him that a human skull had been found and buried. Gallagher stated it was found “on the Southeast end of the island about 100 feet above [the] ordinary high water springs.”

Gallagher visited the site, and in a “thorough search” he recovered more bones and various artifacts. He excavated the buried cranium, and all the bones and artifacts were eventually shipped to the WPHC headquarters in Fiji. His notes and those of Dr. Kingsley Rupert Steenson, senior medical officer, Gilbert and Ellice Islands Colony in Fiji, can be summarized as follows [4][5]:

1. A total of 13 bones were found “lying under a 'ren' tree.” These included the cranium, which had been found and buried before Gallagher arrived in September 1940. “Ren” is the I-Kiribati (Gilbertese) word for Heliotropium foertherianum, formerly (until 2003 ) known as Tournefortia argentea.[6] 

2. “Remains of [a] fire, turtle and dead birds” were also noted.

3. “Part of” [a shoe] “sole” [that] “appears to have been a stoutish waking shoe or heavy sandal” was found, along with a Benedictine bottle “alleged to have been found near [the] skull.” During later discussions of artifacts found with the bones, Dr. Kingsley R. Steenson in Fiji mentioned “corks on brass chains [that] would appear to have belonged to a small cask.”

4. “[A] sextant box [with] two numbers on it 3500 (stenciled) and 1542” was located, but “……no sextant was found.  Only part discovered was thrown away by finder but was probably part of an inverting eyepiece.”


Dr. Hoodless Examines the Bones
Gallagher shipped the bones and artifacts from Nikumaroro to the WPHC headquarters in Fiji. There the bones were examined and measured by Dr. D.W. Hoodless, principal of the Central Medical School. The bones, along with all the artifacts collected at the time, were subsequently lost, but Dr. Hoodless' notes have survived, including the measurements and methods he used to estimate the sex, age and stature of the individual whom the bones represented.

Dr. Hoodless estimated the height of the individual using Karl Pearson's formula for stature [7] to be 5'5.5". Pearson's 1898 formula was based on Manouvrier's French sample, consisting of only 50 individuals of each sex. These were individuals whose birth years would likely have been in the early 19th century and who were substantially shorter than modern Americans or even Americans of the late 19th century. Various sources state that subsequent analyses have shown Pearson's formula to underestimate actual stature.[8]

Dr. Hoodless arrived at the estimated height by averaging height extrapolations from the three long bones recovered, namely the humerus, radius and tibia.

Richard Jantz, professor emeritus of the Department of Anthropology at the University of Tennessee, Knoxville and Earhart-Noonan researcher Joe Cerniglia have discovered errors in Hoodless' analysis. These analyses, although worthwhile to note, do not significantly alter Hoodless' height estimate. A further explanation of these errors by Cerniglia may be detailed in a forthcoming report on this blog.

Hoodless opined: "It may be definitely stated that the skeleton is that of a MALE." [emphasis in the original] "...it is probably not that of a pure South Sea Islander - Micronesian or Polynesian. It could be that of a short, stocky, muscular European, or even a half-caste, or person of mixed European descent."

Re-analysis of the Hoodless Measurements
In 1998 the late Karen Burns and Richard Jantz employed the discriminant function program FORDISC 2.0[9] to analyze Hoodless’ cranial/skull measurements to estimate the castaway’s race and sex.[10] They concluded the skull was more likely European than Polynesian, although it could not be excluded from any population. The FORDISC analysis indicated the individual was most likely female, but the level of certainty was very low (.65/.35).

In the same paper Burns and Jantz estimated stature/height by employing formulae derived from a modern sample (Ousley 1995) in the forensic anthropology data bank at the University of Tennessee. This analysis determined that the “best estimate” for the individual’s height is: 

If female: ca. 5'6.1" to 5'7.6"
If male: ca. 5'8.0" to 5'8.4"
Confidence Interval (male and female): ca. 5'4" to 5'10"

These estimates were updated in December 2018 as discussed below.

Burns and Jantz noted that Amelia Earhart gave her height as 5'8"; however, there are indications that she was closer to 5'7". A regression analysis of bone length from stature for women of 5'8" and 5'7" indicated that the 1941 bones fit Amelia Earhart’s stature very well.

The paper concluded that it is “impossible to know whether the bones inspected by Dr. Hoodless in 1941 were in fact those of a white female and if anything even less possible to be sure that they were those of Amelia Earhart.”

In 2015, Pamela Cross and Richard Wright published a challenge to the Burns, Jantz et al. analysis.[11] In brief, Cross and Wright argue that: “A critical review of both investigations and contextual evidence shows that the original [Hoodless] osteological analyses [Pearson’s formulae] were made by experienced, reliable professionals, while the cranial [FORDISC] analysis is unreliable given the available data. Without access to the missing original bones, it is impossible to be definitive, but on balance, the most robust scientific analysis and conclusions are those of the original [Hoodless] finding indicating that the Nikumaroro bones belonged to a robust, middle-aged man, not Amelia Earhart. Hoodless’s methods were sound and therefore his [male] sex estimate was likely correct.” 

In February 2018, Dr. Jantz published a response to Cross and Wright, including a detailed re-analysis of the Hoodless measurements employing FORDISC 3.1 and other data. The first part of Dr. Jantz’s paper, which examined “the methods Hoodless used and which were so vigorously defended by Cross and Wright,” stated:

“Cross and Wright (2015) argue that Pearson’s formulae are still in use today. I am not aware of any contemporary forensic anthropologist that uses Pearson’s formulae. By any reasonable standard, the height of 65.5 inches (5'5.5") presented by Hoodless and supported by Cross and Wright must be considered an underestimate. I will also show [in this Feb. 2018 paper] that estimating sex from the half subpubic angle supported by Cross/Wright is by no means foolproof.”

The second part of the paper reconstructed Amelia Earhart’s “height, weight, body build and limb lengths and proportions” to “allow explicit evaluation of the bones found in 1941 against Earhart to determine whether or not she can be excluded or included.”

The paper noted that the estimated lengths in millimeters of Earhart’s humerus (321.1), radius (243.7) and tibia (372) are very close to the corresponding castaway’s bones measured by Hoodless (325, 245, and 372).[12] 

Earhart’s estimated bone lengths were compared with the 2,776 individuals in the FORDISC 3.1 database. Her ranking numbers were converted to likelihood ratios as described by Gardner and Greiner (2006), resulting in ratios ranging from 84 to 154. Those likelihood ratios, quoting the paper, “would not qualify as a positive identification by the criteria of modern forensic practice where likelihoods are often millions or more.” However, the paper stated they do qualify as a “preponderance of evidence” and “if the bones do not belong to Amelia Earhart, then they are from someone very similar to her.”   

Jantz noted certain caveats, however:
“It should be mentioned that a sample of Micronesian or Polynesian bone measurements was unavailable to test against the Nikumaroro bones. I consider it highly unlikely that inclusion of such a sample would have changed anything. As Figure 3 [in the original paper] shows, the Nikumaroro bones are more similar to Euro-Americans than they are Micronesians or Polynesians, which suggests they would produce even fewer nearest neighbors.”

“[In the case of the Nikumaroro bones] it is impossible to test any other hypothesis, because except for the victims of the Norwich City wreck, about whom we have no data, no other specific missing persons have been reported. It is not enough merely to say that the remains are most likely those of a stocky male without specifying who this stocky male might have been” (emphasis added).

As discussed below, some data are now available regarding the Norwich City wreck victims.

The SS Norwich City
The Normanby, later renamed Norwich City, was christened and launched on July 12, 1911, by the British shipbuilding company William Gray and Company of West Hartlepool, England. She was assigned yard number 792. She was registered out of London by the London and Northern Steamship Company as ship number 132596. The 397-foot bulk carrier had a beam of 53 feet 5.5 inches.

The London and Northern certificate was cancelled on April 24, 1919, when the ship was re-registered at Bideford, England to the St. Just Steamship Company, Limited. Sir Reardon Smith Lines, Limited was assigned to manage the vessel.

On July 2, 1928, nine years to the day before Amelia Earhart and Fred Noonan disappeared in 1937, St. Just was absorbed into the Sir Reardon Smith Lines, Limited. After William Reardon Smith started managing the vessel, her name was changed to the Norwich City by the Board of Trade (minutes No. 2544).

Last Voyage: Wrecked on Gardner Island (Nikumaroro)
The Norwich City departed the Australian City of Melbourne, in the state of Victoria, with a crew of four (4) officers and thirty-one (31) crewmen (35 total) bound for the City of Vancouver in the Canadian province of British Columbia. She was scheduled to lay over in the City of Honolulu within the United States territory of Hawaii. At approximately the halfway point en route to Honolulu, she encountered a cyclonic weather disturbance with powerful westerly winds and heavy seas. Strong currents threw the ship off its course. Shortly after 11:00 p.m. on the night of November 29, 1929, while facing torrential rain, high winds, and heavy seas, the Norwich City ran aground on Nikumaroro’s fringing reef. She ended up hard aground north of what would later come to be known as Tatiman (pronounced “TASS-i-mun“) passage, the main inlet to the atoll’s lagoon.

Abandoning Ship
Captain Daniel Hamer had the bridge watch when the Norwich City grounded. He gave the order to don life jackets and prepare the lifeboats. After three hours, radio contact was made with Apia, Western Samoa. Apia Radio attempted to contact vessels in the vicinity of Nikumaroro, but none could be located closer than 850 miles from the atoll. At 4:00 a.m. smoke was streaming from the engine room. The wireless operator reported the fire to Apia. After lowering the starboard boat to the gunwale, Captain Hamer and the chief officer went to the port boat to lower it. At this point a wave slammed into the weather side of the ship carrying the lifeboat away. Captain Hamer was thrown into the sea 40 feet below and given up for lost although he in fact survived and struggled ashore. Chief Officer Thomas was swept inboard but was not seriously injured. At 5:15 a.m., Thomas ordered the starboard lifeboat lowered, which contained the remaining crew. When they let go the lines, the lifeboat was swept away aft and capsized by waves. All of the men were now in the water at the mercy of the seas. The men were repeatedly swept onto the island’s reef and then back out to sea.

The Fate of the Crew
Twenty-four of the Norwich City crew members, including Captain Hamer and First Officer Thomas, made it to shore and were later rescued. Exhibit 1 lists their names and titles, extracted from newspaper accounts.

Eleven crewmen were lost, identified as John James Leslie, John Thomas Jones, James William Horne, Thomas Edward Scott, Francis Sumner, Redman Yousef, Saleh Ragee, Said Metanna, Ayed Naif, Ahmed Hassan, and Ali Hassan. All of these were listed in the official records as "deceased, Norwich City."

Three of the eleven lost sailors’ bodies were recovered and buried on Nikumaroro by the survivors. Two of them were identified in various reports as Mr. Leslie and Mr. Jones; the latter stumbled ashore, collapsed and could not be revived. The third man buried was one of the six Arab crewman listed in Table 1; his name is to date unknown.

Eight crewmen were not recovered by the survivors. Screams were heard from one of the Yemeni seamen, leading to the surmise that he had been attacked by sharks.

Yousef's CR1 height data field is blank. For Yousef, and the others, the search for additional records, such as CR10, crew agreements and lists, is ongoing.
4. In addition to Leslie and Jones, one of the six Arabs listed in this table was buried on the beach on Gardner Island. Jones' birthdate, height, eye color and hair color were obtained from a CR10 card.
5. A Welsh newspaper listed the address for the 6 Arabs as: 132 Commercial Rd, South Fields, which is perhaps a boarding house.

In summary, eleven men were killed in the wreck of the Norwich City. Three bodies were recovered and buried near the wreck site – i.e. on the northwest shore of the island about four miles from the location at the southeast end where bones were subsequently found. The remaining eight men were all missing and presumed dead.

After the Wreck: Reports of Bones on Nikumaroro
In addition to the officially reported 1940 discovery and recovery of the thirteen human bones, human bones were reported on the island on several occasions after the Norwich City wreck [13]:

1938, USCG Taney

The U.S. Coast Guard Cutter Roger B. Taney visited Hull Island in the Phoenix Group (now Orona) in 1938.[14Captain J.W. Jones lived on the island as a coconut plantation manager for Messrs. Burns, Philp, (South Sea) Company Limited. The following passage is from the report written by the U.S. Department of Interior representative aboard the Taney:

"Mr. Jones told us of the wreck of the Norwich City on Gardner Island. She struck in 1919 [sic: 1929], and the [ship] Makoa saw her [Norwich City] recently and stated there was much good material aboard her such as anchors, winches, etc. The bodies of nine [sic] men lost in the wreck, drowned or killed by sharks (he said) were buried ashore, but wild pigs dug them up and their skeletons now lie on the beach. The survivors were taken off the island."

Author Notes: The Norwich City wreck is on the end of the island opposite to the “South East [sic] corner” where Gallagher describes recovering human bones in 1940. Jones is quoted as saying that someone aboard Makoa saw human bones on the beach, presumably near the Norwich City wreck. Note the similar references below by Bauro Tikana and Emily (Segalo) Sikuli. There is no historical record of wild pigs living on Nikumaroro prior to its settlement as part of the PISS in 1938-39; Jones’ description of the bodies having been excavated by wild pigs appears to be conjecture. Erosion is the more likely culprit followed by the scattering of the bones by coconut crabs.

1941, Dr. Kingsley Rupert Steenson
Dr. Steenson, senior medical officer, examined the bones and artifacts after they were delivered to Suva, Fiji. In addition to his aforementioned reference to “corks on brass chains,” he noted in the official file: “they appear to be parts of shoes worn by a male person and a female person.”

Author Notes: Dr. Steenson is suggesting the castaway site contained two different pairs of shoes demarcated by gender. This is suggestive, but it does not prove there were two castaways. As noted in Table 2, the bones recovered by Gallagher are likely from one person. The potential pitfalls of determining gender based on how a shoe looks are discussed elsewhere in this report.

1960, Floyd Kilts
The U.S. Coast Guard operated Loran Unit 92 on Nikumaroro Island from 1944 to 1946 inclusive. Floyd Kilts was on duty there in 1946. In July 1960 an article written by Lew Skarr appeared in the San Diego Tribune.[15Skarr quotes a story Kilts said he was told in 1946 through an interpreter by a “native” on the island. Quoting Kilts in the news story:
“It seems that in the latter part of 1938 there were 23 island people, all men, and an Irish magistrate planting coconut trees on Gardner….”
“They were about through and the native was walking along one end of the island. There in the brush about five feet from the shoreline he saw a skeleton.”
“What attracted him to it was the shoes. Womens shoes, American kind. No native wears shoes. Couldnt if they wanted to—feet too spread out and flat. The shoes were size nine narrow. Beside the body was a cognac bottle with fresh water in it for drinking.
“Farther down the beach he found a mans skull, but nothing else.”

Author Notes: Elements of the Kilts story resemble, and presumably reflect, the story documented in the Western Pacific High Commission files. There were 23 colonists on the island at one point in time, and a skull, shoe parts and a bottle were found while preparing to plant coconuts. Gerald Gallagher was of Irish descent, and was nicknamed “Irish.” The possibility that the colonists first found a skeleton and then later a skull is a perspective to consider.

1991, Bauro Tikana
Mr. Tikana was Gerald Gallagher’s clerk and interpreter in 1940. The following is excerpted from a facsimile (fax) dated August 12, 1991 that Mr. Tikana sent to Ric Gillespie, executive director of The International Group for Historic Aircraft Recovery (TIGHAR):
“When we first arrived (in 1940) I saw the [Norwich City] shipwreck and asked Mr. Gallagher about it. He told me that it was the Norwich City. Later when the laborers were cleaning (clearing the bush) they told me they found bones near the ship. I do not know if Mr. Gallagher knew about the bones as I didn’t tell him about it. The laborers also told me they found bones on the other end of the atoll when they were cleaning the land in that area. I don’t believe Mr. Gallagher knew of these as he was the only white man there and most of the laborers didn’t speak English and were afright [sic] to talk to him and Mr. Gallagher didn’t speak Gilbertese. I did all the interpreting for Mr. Gallagher and pass on all his instructions to the laborers.”

1999, Emily (Segalo) Sikuli
Mrs. Sikuli was the daughter of the Nikumaroro carpenter. Emily does not claim to be a witness to the finding of bones near the Norwich City, but in interviews with TIGHAR personnel [16she states that bones were found near the Norwich City wreck by fishermen. They were turned over to Teng Koata, the Native Magistrate, who then restricted access to the area. She said the bones were turned over to Gallagher and placed in a box.
   
It may be that Mrs. Sikuli’s recollections are not accurate reflections of events in 1940. But it is reasonably clear that bones were discovered somewhere near the Norwich CityA 1999 interview with Otiria O’Brian [17], who lived on Nikumaroro for a short time, corroborates some of Emily’s recollection. 

Could the Bones Discovered in 1940 Represent One of the Lost Norwich City Crewmen?
In November 1998, while conducting research at the National Archives in Kew, England, the author obtained the heights of two of the Norwich City crewmen  Thomas Scott and Francis Sumner. This information was obtained too late to be considered in the Burns et al. December 1998 paper [18], which was published a few weeks later. In January 2018, the data were forwarded to Jantz, who had not previously seen them, but it was too late to include in his February 2018 paper.[19]

In August 2018 the author uncovered the heights for two missing Yemeni/Arab crewmen named Saleh Ragee and Said Metanna; these were also provided to Dr. Jantz. Given that Ragee’s height was very close to the “best estimate” for the castaway’s height listed in the 1998 paper, Jantz re-employed FORDISC 3.1 and other methodologies. See Exhibit 5During the ensuing years additional data points had been added to the FORDISC database on top of the program, which improved its ability to estimate height from bone length. Jantz re-estimated the castaway’s stature based on Hoodless’ measurement of the skeleton’s humerus, radius and tibia. Francis Sumner's height (5'3") places him below the 90-percent confidence interval; thus, it is probable that he is not a candidate to have been the Nikumaroro castaway. Said Metanna (5'4") and Thomas Scott (5'9"+) are near the lower and upper 90-percent confidence limits, respectively, and thus are candidates with a low probability to have been the Nikumaroro castaway. Saleh Ragee's height (5'6") is close to the most likely height range estimate and thus is a good fit for the Nikumaroro bones. See Table 2. Ragee and the other five Yemeni/Arabs listed in Table 1 have a one-in-six chance of having been buried on the beach.

Shoe Parts: Did Gallagher Find a Norwich City Arab's Sandal
Gallagher stated the following about the shoe parts he collected in association with the bones:

“[We found] part of [a shoe] sole [that] “appears to have been a stoutish waking shoe or heavy sandal ... My conclusion … [that the] Shoe was a woman’s… [is] based on sole of shoe which is almost certainly a woman’s ... probably size 10." The senior medical officer in Fiji, Dr. Steenson added: “they appear to be parts of shoes worn by a male person and a female person.”

Five of the lost Norwich City seamen were Arabs from Yemen. Arab seamen, like almost all non-European sailors aboard steamships, were referred to as lascars,[20] and often wore sandals and sometimes went barefoot. This was due to economics, Arabic tradition, and the extremely hot conditions below deck in the engine room where they often toiled. Another reason to wear open sandals or to work barefoot was, for example, to provide a better grip on the decks of dhows.[21] Lascar sailors hailed from backgrounds and cultures that included Arabic, Cypriot (Cyprus), Chinese, Indian and East African.[22] Sandals are common footwear in all of these locales.

Sandals are an essential part of the tradition and lifestyle of Arabic nationals. Sandals, often open-toed, are the preferred footwear of both Arabic men and women in regions such as Yemen, where heat and humidity make this style of "cooler" footwear preferable.

Arabic tradition does not allow for people to wear footwear/sandals on carpets/rugs or in places of worship; footwear is not usually worn in living quarters. Sandals are popular in part because they are easy to take on and off before entering and leaving living quarters or places of worship.

Heavy-soled sandals are commonly worn by men in the Middle East, Asia, North Africa, and surrounding locales. That was true in 1929, and for centuries before that, as it is today. Arabic sandals are worn at work (in office, agricultural, and industrial settings), and in both formal (e.g. weddings) and informal (e.g. relaxing) contexts.

Norwich City seaman/Arabs Redman Yousef, Saleh Ragee, Said Metanna and Ayed Naif worked in the engine room as firemen/stokers, with Yousef and Naif also serving as trimmers. See Table 1, Exhibits 3 and 4. Firemen shoveled coal into the Norwich City's boiler to produce superheated steam for propulsion. The trimmers delivered coal to the firemen from the ship's coal bunkers. These engine room jobs were dirty, low-paid and dangerous. It was not uncommon within the shipping industry for a fireman or trimmer to collapse while laboring in the engine room, where temperatures could reach as high as 120 to 160 degrees Fahrenheit. There are recorded instances of engine room workers becoming temporarily insane, rushing to the deck and jumping overboard to escape the heat.[23]

Men’s Arabic sandals can have a distinctive look that might appear feminine to the eyes of a westerner such as Gallagher or Steenson. The soles of Arabic sandals often have elaborate stitching patterns, as do the uppers. In the Arabic sandals, shown below, note their "feminine" look to the western eye/culture and their thick "heavy" soles. The soles themselves often have intricate designs sewn into them unlike, say, shower sandals or casual sandals worn by men in the western world.

Corks on Brass Chains: Norwich City Provisions?
The senior medical officer in Fiji, Dr. Steenson, stated after observing the artifacts Gallagher forwarded with the bones: “corks on brass chains would appear to have belonged to a small cask.”

Early 20th century ships such as the Norwich City used wooden casks to contain water and other liquids; these often had corks as stoppers, attached by chains. Water casks were often standard issue in lifeboats. The Norwich City’s Second Officer, Mr. Lott, reported that there were small water casks (referred to as “breakers”) stored aboard the Norwich City lifeboats. Lott stated:

“[After swimming ashore] we then gathered what stores we could from the lifeboat. Both boats were washed ashore. … I found a pool of fresh water on the morning of Saturday. By next morning [it] was turned to salt water and undrinkable. We had the breakers from the lifeboats.”

Sextant Box, Two Numbers on it, 3500 (stenciled) and 1542
Earhart-Noonan researcher John Kada, with input from fellow researcher Lew Toulmin, published research in October 2018 regarding the aforementioned sextant box Gallagher described. Kada’s data indicate that the box, and presumably the reported apparent inverting eye piece, likely belonged to a U.S. Navy survey crew.[24The USS Bushnell’s survey crew camped on the island for seven days, November 28 to December 5, 1939 inclusive.[25A four-page memo dated November 15, 1938, lists sextant instruments from the Bushnell, which were to be sent to the Naval Observatory for maintenance. Item 12 on the list is “Sextant, Brandis N.O. [Naval Observatory] 1542 General Overhaul.” The sextant box found on Nikumaroro was marked with the numbers 3500 and 1542. See Exhibit 6

Summary
In 1929, the SS Norwich City ran aground on the then-uninhabited Nikumaroro Island within the Phoenix Islands. In 1937, Amelia Earhart and Fred Noonan disappeared in the Pacific presumably somewhere in the region of the Phoenix Islands. In April 1940, colonists supervised by Gerald Gallagher, a British Western Pacific High Commission (WPHC) officer, recovered thirteen human bones on Nikumaroro Island.

Evidence found with the bones (remains of a fire, bird bones) indicated the deceased had lived as a castaway. Artifacts collected with the bones included: parts of shoe(s) that appeared to be a stoutish walking shoe or heavy sandal, a Benedictine bottle, a sextant box and corks attached to brass chains. It was suggested in 1940 that the shoe parts belonged to a woman “based on [the] sole of [the] shoe,” It was suggested the bones might belong to Amelia Earhart. The WPHC had the bones examined by a doctor in Suva, Fiji in 1941. The doctor concluded they belonged to a male about 5'5.5" inches tall. He went on to say the person was “a short, stocky, muscular European, or even a half‐caste, or a person of mixed European descent.”

Analyses published in December 1998 and February 2018 posited the bones may have belonged to Earhart. The 1998 analysis presented evidence that Earhart’s height was 5'7" to 5'8". A December 2018 analysis of the 1941 bone measurements indicates that the most likely height for the castaway was 5'6" to 5'8".

Eight crewmen from the Norwich City shipwreck were not located. Heights for four of them have been obtained. Three of them are not likely to have been the castaway; each was either too short or too tall (though none is impossible as a match). The height of the fourth seaman, Saleh Ragee, is listed as 5'6". Ragee is thus a candidate for the skeleton found in 1940.
   
The missing crewmen, including Saleh Ragee, included Arabs from Yemen. Arabs traditionally wear heavy-soled sandals with elaborate stitching, which to a person from a western culture would look feminine.

The lifeboats from the Norwich City contained wooden casks filled with water that very likely would have had corks on brass chains attached to them.

A 2018 paper provided evidence that the sextant box mentioned in the WPHC correspondence was likely from a November to December 1938 U.S. Navy survey of Nikumaroro.

Exhibit #3:
British Merchant Seaman Records: Summary of CR Cards
The Merchant Navy Seamen (see Exhibit 7) (1918-1941) records include Central Indexed Register of Seaman Cards which is sometimes referred to as the Fourth Register of Seamen Index Cards. The term “Central Register” is abbreviated CR (i.e. CR cards). The United Kingdom’s (U.K.) Registrar General of Shipping and Seamen used the index between the two world wars to produce a centralized index of merchant seamen serving on British merchant vessels. The U.K.’s Board of Trade issued these cards. This report discusses three types: CR1, CR2 and CR10. There are two or more cards for some individuals. The CR cards are in volumes within the U.K.’s National Archives record series BT 348, BT 349, BT 350 and BT 364. The originals are held by the Southampton Archives. The Central/Fourth Register was started in 1913; however, the records for 1913 through 1917 were destroyed.

CR1 cards have data fields for, among other things:

Discharge Assigned No. (Dis. A. No.), birthdate/place, sailor’s height and eye/hair color. Each sailor was assigned a unique “discharge assigned” number (Dis. A. No.), similar to a social security number, and a Seaman’s Discharge Book (SDB). The SBD contains a record of the sailor’s sea time, certificates the sailor earned and the ships on which he served.

CR2 cards have data fields for only: Dis. A. No., Certificate of Competency No., birth year/place, rank/rating, ship and date of engagement (no physical characteristics of the sailor). Certificate of Competency is a form of license granted to mariners to work on ships.

CR10 cards are similar to CR1 cards. They have data fields for among other things: Dis. A. No., birthdate/place, sailor’s height and eye/hair color, nationality and next of kin information.

The seaman CR1 cards containing height information for “lost” Norwich City sailors were located for Scott, Sumner, Ragee and Metanna (see Table 1). “Lost” seaman CR cards for Horne (CR2), Yousef (CR1 and CR2) and Naif (CR2) were located but those CR cards do not list their heights. The CR cards that have been located to date are below in Exhibit 4. Note that John Thomas Jones, who was buried on the beach, is the only sailor so far with a CR10 card. Locating Horne's, Naif's, and the two Hassans’ CR1 or CR10 cards, if they exist, may reveal their heights.

When this research was started in 1998 the records were accessed on microfiche at the Public Record Office in Kew, England. Many of the CR records are now available at www.findmypast.com.

Exhibit #5:
Statistical Methodology Used for Table 2
(The following exhibit is derived from personal correspondence with Dr. Richard Jantz.) 

The Norwich City crewmen were male, so male samples were analyzed for this report. Three samples were analyzed for this report: Forensic statures for 20th century males, measured statures World War II males (Trotter), and cadaver statures for 19th century males. Three bone lengths (Humerus (H), Radius (R), and Tibia (T)) and four cumulative bone lengths (H+T, H+R, R+T and H+R+T) were plotted on the x-axis versus height on the y-axis (i.e., seven sets of x-y data within each sample, 21 total). A confidence interval with upper and lower limits was calculated for the 21 sets of x-y data.

The bone length values for the Nikumaroro castaway were tabulated: H=324 mm, R=245 mm, T=372 mm, H+T=696 mm, H+R=569 mm, R+T=617 mm and H+R+T=941 mm. The castaway's bone length(s) were marked on the x-axis of the plots that represented that x-axis variable. For example, the castaway's humerus+tibia value of 696 mm was marked on the three x-y plots representing humerus+tibia versus height (one H+T plot for each sample). A vertical line above that bone(s) length (e.g., 696) revealed three points on the sample's x-y plot: i) upper and ii) lower 90-percent confidence limits (CL) and iii) a best height estimate (point estimate) for a person with the castaway's bone length(s). A prediction interval (PI) was then calculated for those three points (i.e. 21 PIs total). The PI equals the absolute value of the difference between the upper and lower CL divided by two, which is the distance between the castaway's best height / point estimate and the CL limit above or below the point estimate. PI is a measure of dispersion. Lower PIs indicate estimates that are less dispersed. These are generally given greater weight than estimates with higher PIs, which are more dispersed.

With PIs obtained from a combination of the x-y sets of data and the castaway's bone length(s) in hand, the lowest PI from the seven possibilities was identified within each of the three samples. Any PI within the sample that shared the lowest PI was also selected. For example, the T and H+T PIs were equal within each sample. This filtering process led to 11 PIs corresponding to CL limits associated with a best height estimate. From this filtration process, a global minimum lower 90-percent confidence interval value and a global maximum upper 90-percent confidence interval value from the 11 choices were selected. These CL values were then adopted as the overall 90-percent confidence interval (64 to 71 inches) for the height of the castaway. In addition, a most likely height estimate range for the castaway (66 to 68 inches) was determined from the aforementioned 21 best height estimates (point estimates) for a person with the castaway's bone length(s). See Table 2.

Exhibit #6: 
Sextant Box Paper Excerpt (with added details)

Derived from John Kada’s weblog posting titled “The Probable Origin of the Nikumaroro Sextant Box”

Date of original weblog: October 26, 2018
Gallagher stated the sextant box had two numbers on it 3500 (stenciled) and 1542. Sextants (and their boxes) in the early decades of the twentieth century were often marked with two numbers. One is the sextant manufacturer’s serial number. The other is a number assigned by the U.S. Naval Observatory, which had the task of inspecting and maintaining sextants to include those used by the U.S. Navy.

From November 28 to December 5, 1939, roughly four months before the castaway’s remains were found, the USS Bushnell, a U.S. Navy submarine tender, visited Nikumaroro [Gardner] Island. She was outfitted as a hydrographic mapping vessel sent to survey the island, its lagoon and surrounding sea bottom. The Bushnell made a short trip to McKean Island during this period leaving the lagoon survey party camped on the island. Maps of the survey illustrate that a network of reference points were established throughout the island. The work included measuring water depths from boats making transects across the lagoon.

Earhart-Noonan researcher John Kada uncovered a hydrographic surveying manual published by the U.S. Coast and Geodetic Survey in 1931. It illustrated that sextants were used to triangulate/determine positions on land-based reference points when making transects of this sort.

In December 2016, Kada visited the National Archives and Record Administration (NARA) in Washington D.C. to view Bushnell records. He confirmed through the Nikumaroro survey notes that sextants were utilized on the island in 1939. The notes did not include sextant numbers.

Kada’s second trip to NARA in August 2018 also did not uncover any information on the Bushnell’s sextants. The trip was prompted by a sextant box-related paper that fellow researcher Lew Toulmin presented at the May 2018 Earhart-Noonan Symposium during the Archaeology Channel Conference on Cultural Heritage Media in Eugene, Oregon.

Toulmin’s research also included an earlier trip to NARA. At NARA Toulmin examined an index card catalog for NARA’s holdings of the U.S. Naval Observatory’s correspondence for the period 1909-1925. The card catalog was organized by subject, and included a card for sextants. 

Kada’s third visit to NARA in October 2018 revealed a four-page memo from the USS Bushnell dated November 15, 1938, listing sextant instruments to be sent to the Naval Observatory. Item 12 on the list is “Sextant, Brandis N.O. [Naval Observatory] 1542 General Overhaul.” A note penciled into the margin indicates that this sextant was returned to the Bushnell on January 17, 1939. This documented that a Brandis sextant with N.O. number 1542 was refurbished by the Naval Observatory in late 1938 and returned to the Bushnell by January 1939, about one year before the Bushnell crew surveyed Nikumaroro. It is probable that the sextant box found on Nikumaroro marked with the numbers 3500 and 1542 was a Brandis sextant box that a Bushnell surveyor lost.


Exhibit #7: 
Definitions

90-Percent Confidence Interval The upper and lower height values between which 90 percent of the estimated heights of a given sample are expected to fall. It is assumed that an unknown data point, such as the bones discovered on Nikumaroro Island, will fall within these limits, as long as it is drawn from the same or similar population used to estimate the confidence limits.
The term "90-percent" indicate that 90 percent of the experiments, in this case measuring heights of many individuals, include the true mean/average, but 10 percent will not. So there is a 1-in-10 chance (10 percent) that the confidence interval does NOT include the true mean. So the interval could shift upwards or downwards over the course of many experiments.
Able-Bodied seamen perform general maintenance, repair, sanitation and upkeep of material, equipment, and superstructure areas in a ship’s deck department. Maintenance can include chipping, scraping, cleaning, priming, and painting a ship’s metal structures.
Aft is the rear (stern) of a ship as you face forward 
Apprentices typically work in the deck or engineering departments of a ship. Apprentices can advance to be officers or other higher-ranking seaman.
Boatswains are in charge of hull maintenance and related work. The hull is the watertight body of the ship.
Breaker: As a nautical term: A small water cask often used in lifeboats. Credit to Richard Gillespie, executive director, The International Group for Historic Aircraft Recover for reviewing this report and alerting me to Second Officer Lott’s quotation regarding breakers.
Cabin Boys wait on the officers of a ship and run errands for the captain.
Chief Engineer is responsible for the engine room and maintenance and other machinery and support systems on a ship, both above and below the ship’s deck. The chief sometimes has a rank similar to the master/captain.
Chief Officer is second-in-command after the ship's master/captain.
Confidence Limits: These are the numbers at the upper and lower end of a confidence interval.
Donkey-men are in charge of a donkey-engine, a small steam-engine, usually for subsidiary operations on board ship, as in feeding the boilers of the propelling engines.
Fireman or stoker is a seaman whose job is to tend the fire for the running of a boiler to power the steam engine. On land-based steam locomotives, the term fireman is usually used, while on steamships and stationary steam engines, such as those driving saw mills, the term is usually stoker (although the British Merchant Navy did use firemen). Much of the job is hard physical labor, such as shoveling fuel, typically coal, into the boiler's firebox.
Forward means toward a ship’s bow.
Fourth Engineers work in the engine department. They are responsible for electrical, lubricating oil, bilge and other tasks. They are sometimes referred to as assistant engineers or third engineer.
Galley Boys assist in the ship’s kitchen.
Gunwale: The gunwale is the top edge of the side of a boat or ship.
Master is the highest grade of licensed mariner, who is qualified to serve as the captain of a merchant ship of any size, of any type, operating anywhere in the world. In the British Merchant Navy a master mariner, who has sailed in command of an ocean-going merchant ship, is titled captain.
Merchant Navy is a term given to commercial (civilian) passenger and shipping fleets in the United Kingdom (U.K.). The United States' “Merchant Marine” is equivalent to the U.K.’s Merchant Navy. In the U.K. the military/naval fleet is called the Royal Navy.
Mess Room Boy duties are many and varied. They include: coffee, assistant cook, pantry, waiter, dishwasher, bedroom steward, and porter.
Population The broader group of individuals for whom you intend to generalize your height estimates in an analysis of the sample. For example, the population might be all the Arab males living in Yemen. The sample is a subset of the population.
Port is the left side of a ship as you face forward.
Sample A group of individuals for which, for example, heights were recorded. For example, the height of 2,000 male Arabs living in Yemen. 
Second Officer is the third-in-command on a merchant vessel.
Starboard is the right side of a ship as you face forward.
Third Officer is customarily the ship's safety officer and fourth-in-command.
Trimmers ensured that the coal was evenly distributed within the holds of the ship as it was fed into the boilers. This ensured that the "trim" or level of the ship was not adversely affected. Trimmers fed coal to the firemen through chutes or often in carts, which were dumped near the boilers.
Wireless Operators operate the radio transmitter on a ship.
