Amelia Earhart
Amelia Earhart, Fred Noonan, and the Lockheed Electra, 1937

Today we're going to point the skeptical eye at some of the rumors surrounding one of the twentieth century's great mysteries: The disappearance of pioneering woman aviator Amelia Earhart, when her airplane disappeared over the Pacific Ocean on her famous 1937 flight around the world. Conventional wisdom says that she simply ran out of fuel and ditched into the ocean, but stories have persisted for decades that she might have made it safely to an island, perhaps even survived for some time. Here and there, various artifacts have been found: A shoe, a zipper, a scrap of aluminum. There are even some crazy stories: that she made it back to the United States and lived out her life under an assumed name, or that she was captured by the Japanese and executed as a spy. Let's take a look to see if any of these alternate explanations can withstand scrutiny.

Amelia Earhart and her navigator, the highly experienced and esteemed Fred Noonan, were on the third-to-last leg of their circumnavigating flight in her Lockheed Electra 10E, a 1200 horsepower, state-of-the-art twin engine aircraft. They took off from Lae in Papua New Guinea on July 2, 1937, headed for a remote refueling stop in the South Pacific, a tiny island called Howland. From there they would continue to Honolulu for a final refueling before completing the journey in Oakland, California.

And as everyone knows, they never made it to Howland. A US Coast Guard cutter, the Itasca, was on station at Howland transmitting a radio direction-finding signal, and made sporadic voice contact. Most historians agree that a half-hour time zone difference disrupted both parties' attempts to establish two-way voice communication, and a photograph of the Electra taking off from Lae appears to show that a belly antenna (of unconfirmed purpose) may not have been in place. And to top it off, it turns out that Howland's position was misplaced on Earhart's chart by about five nautical miles, but which would still have kept it within visual range. Whatever role these problems may have played, if any, is unknown; but Earhart's final radio transmission to the Itasca said they were in the immediate vicinity of Howland. And ever since then, the best analysis is that they ran out of fuel, ditched in the Pacific Ocean, and perished.

But one group of historic aviation enthusiasts called TIGHAR (The International Group for Historic Aircraft Recovery) has been tirelessly promoting their hypothesis that Earhart and Noonan flew not to Howland, but by mistake to an island 650 km to the southeast, now called Nikumaroro but then called Gardner, where they crashed and survived for a time as castaways. TIGHAR's hypothesis and claimed discoveries saturate virtually all television and print reports of Earhart for the past decade, but these media outlets almost never mention that TIGHAR's is a fringe theory supported by poor evidence and that has almost no serious support from mainstream historians or archaeologists.

Here's the problem with TIGHAR's findings. Even though they meticulously document and preserve every artifact, they exhaustively research each one to find matches with real objects from the 1930s, and they look exactly like what such an expedition should look like, their overall methodology is fundamentally, fatally unscientific. It's unscientific in that it's done completely backwards. TIGHAR begins with the assumption that Amelia Earhart crashed, camped out, and died on Nikumaroro. They take everything they find — every anomaly in a photograph or in a story, every piece of bone or manmade artifact found on the island — and try to match it to their assumption, rather than trying to objectively assess its origin.

Nikumaroro, this tiny island where TIGHAR has recovered its artifacts, is in Kiribati, a nation of 100,000 people spread over millions of square kilometers of the South Pacific. People leaving artifacts come and go all the time. For example, pearl divers. Fleets of pearl boats have plied these waters since the 1800s. Every island and reef in the South Pacific has been visited countless times by pearl boats, who anchored, made camp on shore, and spent a few weeks free diving for oysters. Their exploits and histories have been published in dozens of books, such as Roy Miner's 1941 volume Pearl Divers, and the many colorful tales in Frank Coffee's 1920 book Forty Years on the Pacific. TIGHAR found evidence of campfires and fish bones on Nikumaroro and concluded "Amelia Earhart" who is not known to have visited the island; but I found no attempt made by them to exclude the pearl divers who are known to have camped there, and to have done so countless times over more than a century. TIGHAR appears to be dedicated to proving the least likely explanation for the artifacts.

They found an object identified as the heel of a woman's shoe. Many pearl divers were women, and they came from Fiji, the Philippines, and New Zealand, where shoes were not unknown in the 1930s. Could the shoe have come from the 1929 wreck of the steamship SS Norwich City that killed 11 of its 35 crew on Nikumaroro? Could it have belonged to one of the sixteen women who settled on the island in 1939 as part of a British colony? Could the shoe have even floated to the island from anywhere else? I find no reason to exclude the women who lived on or visited the island as possible owners of the shoe, or any reason to suggest Amelia Earhart was the most likely owner.

The found the remains of a buckknife. Is Amelia Earhart really more likely to have brought a buckknife to Nikumaroro than pearl divers, the British settlers, the operators of an 1892 coconut plantation, or the 25 crew of a 1944 Coast Guard station?

At its height, Nikumaroro had a population of about 100 people. Half a dozen smaller populations had come and gone over the prior century, and throughout it all, pearl divers camped ashore. Would you expect such an island to be pristine, or would you expect random debris from not just the 1930s but other periods as well? Without exception, every one of the artifacts recovered by TIGHAR should be expected to have been found there whether or not Amelia Earhart had ever even lived.

This even extends to a partial human skeleton that was found on the island in 1940 during its British colonial occupation. At the time, the young officer who found it, Gerald Gallagher, shipped the bones to Dr. David Hoodless, principal of the Central Medical School of the South Pacific on Fiji. Hoodless studied the bones and reported them to be "definitely" male, judging by the pelvis; and from an individual about 5 foot 5 1/2 inches tall, of European heritage and not a Pacific Islander. No clothes or hair were found, and the bones were severely weatherbeaten and in poor condition.

Near the skeleton, Gallagher also found a small wooden box with dovetailed joints, that he determined to be a sextant box. It was delivered to Harold Gatty, founder of Air Pacific, and a good friend of Fred Noonan and familiar with his navigation habits; for example, that he often carried an old-school sextant with him on flights in addition to modern equipment, just to double-check things the way a good navigator should. Regarding Gatty's own expertise, Charles Lindbergh had described him as the "prince of navigators". Another British officer in the area cabled Gatty's findings back to Gallagher:

Mr. Gatty thinks that the box is an English one of some age and judges that it was used latterly merely as a receptacle. He does not consider that it could in any circumstance have been a sextant box used in modern trans-Pacific aviation.

After studying all these results in light of his original speculation that they may have been related to Earhart, Gallagher wrote:

It does look as if the skeleton was that of some unfortunate native castaway and the sextant box and other curious articles found nearby the remains are quite possibly a few of his precious possessions which he managed to save.

Neither the bones nor the sextant box still exist today, but TIGHAR has made their own analysis of them, based on reading these original reports. As expected, TIGHAR has concluded that the skeleton was consistent with that of Amelia Earhart, and that the sextant box was consistent with one Fred Noonan may have used. Essentially, TIGHAR took the original first-hand expert analyses, and rejected and re-interpreted them to support their desired conclusion.

From a navigational perspective, the fundamental assumption of TIGHAR's theory is almost inconceivable. Fred Noonan was one of aviation's top experts in using the latest navigational techniques and equipment, including the then-new E-6B flight computer, which (among other things) corrects for the effects of wind on speed and course. Nikumaroro is a full five and one half degrees of latitude south of Howland. That's a massive, massive error; it's simply not plausible that Noonan could have been that far wrong. Earhart was no slouch of a navigator either. Could they have made such an error without either of them catching it?

Moreover, the bearing from Papua New Guinea to Howland is about 79° true. To Nikumaroro, it's 89° true. Nikumaroro was about 4272 km away, only slightly farther than Howland, which was 4160 km. The Electra's maximum's range did allow them to make it to either island, but only if they flew an absolutely direct course. The TIGHAR hypothesis suggests that they made their entire flight at a full 10° off course, without catching it, while following their compass and homing in on the Itasca's direction-finding signal, and were as much as five degrees of latitude too far south. Even for 1937, this size of an error strains credibility. Either the E-6B or the sextant would have caught either of these errors easily.

Clarification: The above paragraph has given many readers the impression that I've wrongly interpreted Gillespie's hypothesis. Gillespie does not claim the Electra flew 10° off-course, and does not claim they headed straight for Nikumaroro. Gillespie's basic claim is that they arrived at Nikumaroro, one way or another. The fuel analysis makes his hypothesized dogleg path impossible; this straight line off course is mathematically the only way to make his basic claim workable. I didn't mean for it to sound like I was misrepresenting his hypothesis.

Howland Island, the intended destination, is basically just a flat coral sand cay in the middle of nowhere, about two and a half kilometers long and less than a kilometer wide. It's uninhabited and has no trees, and no structures other than an automated lighthouse beacon. It's about as featureless and bleak as a desert island can be. But in 1937, there was a tiny temporary population there. Hawaii's Kamehameha School for Boys had set up a camp where students would spend a few months learning about the plants and animals there. It was called Itascatown, named after the Itasca that supplied it and handled all the transportation of students.

Three unpaved runways were bulldozed in anticipation of Earhart's landing, but since she never arrived, they ended up having never been used at all. The Japanese bombed them during World War II and they were never repaired.

But back on that day in 1937, the airstrips were ready, the Itasca sat on station off the coast of Howland, and drums of fuel had been sent ashore to refuel Earhart's plane. Coast Guardsmen and teenagers from the Kamehameha School stood watching the skies. They watched and waited, the time for Earhart's arrival came and went, and still they watched. The skies remained quiet. Eventually it became clear that there would be no landing that day, and word gradually spread that the Itasca had lost contact and the plane was now well past the point at which its fuel would have run out.

Following the bearings of Earhart's final radio transmission, just northwest of Howland, the search ships combed the ocean for a week. The aircraft carrier USS Lexington, the battleship Colorado, the Itasca, and even a few Japanese ships scoured the ocean's surface, tiny gray dots on an unimaginably vast shimmering blue curtain. But well hidden, deep in the peaceful darkness thousands of fathoms below them, rested what remains aviation's most enduring legend.

David, Jayne,

"...There have been four deep sea expeditions to date that have searched for Earhart in the vicinity of Howland Island. The first three used a towed sonar but in 2009 the Waitt Institute for Discovery used cutting edge technology, scanning around 2,000 square miles of sea floor to the west of Howland Island using 2 Remus 6000 AUVS. The Remus is very much at the forefront of deep sea technology and its sonar was able to pick up pipes and an oil drum thousands of metres down in the Waitt Amelia Earhart search. Stratus want to use the best technology available in order to be sure that the Electra could not be missed if the area that its in is scanned, and the Remus 6000 is but one of the vehicles that would be ideal for a search of this nature."

WT, yes, I'm aware of those expeditions. I was not aware of the SONAR capability, though. If that technology is refined to be capable of detecting small aircraft at the depths we're discussing, then Boeing can keep their unit in the yard. Mr. Branson (Virgin) also developed a similar deep diving vehicle. These types of systems are what will be required to explore such depths.

I won't deal with whether TIGHER found anything or not. This article's
deficiency seems to be that its author is unaware of what Gillespie has written in his book, Finding Amelia, or has purposefully put words into Gillespies mouth. Gillespie NEVER
claimed that Earhart's flight was 10 degrees off. He clearly believes, as does everyone else, that her plane made a relatvely close approach to Howland, which is obvious to everyone because of the strong radio signal the Itasa received. That mean, dear man, that Gillespie did NOT claim what you falsely claim he said. Gillespie clearly is of the opinion that everyone else shares : that Earhart
began searching for the island, and ended up in the Phenix group, for which there is abundant evidence from direction finding efforts made by reliable sources from several locales in Hawaii. It's conclusive from statements by the Lockheed company that Earhart could not possibly have made radio distress calls (which she clearly did) if she had landed in water. Nor is there the slightest doubt about the photographic evidence about the missing bottom aerial nor about the fact that the aerial was a receiving aerial. Nor is there any doubt as to why Earhart could not get a minimum on her direction finding equipment - she was ignorant of its capabilities. If you want to dispute any of Gillespie's claims, first learn what those claims are. This is article has no credibility.

Kerry, I thinking you misunderstood what I meant by "TIGHAR's theory suggests". The only possible way the plane could have gone to Niku was by a direct course; there was not remotely enough fuel for the dogleg route Gillespie claims. If the plane is there, they would have had to fly 10 degrees off course.

Brian Dunning, Laguna Niguel

Kerry,

I'd have to say that Gillespie has zero credibility.

Carefully study the Pan Am Radio Operator reports. They believed they were picking up signals from Russia, Japan, and/or South America, but not from AE. Not one of the so-called Post-lost radio signals can be accepted as authentic.

Brian,

You keep on repeating, over and over that Earhart's plane could not have made it to Gardner, except by a straight line, yet you have not offered one iota of support for that claim.

By contrast, Tighar, has used Lockheed engineering data and historical records to (they believe) show that the plane could do exactly what they claim, fly from Lae to Howland then to Gardner.

Now, I'm not claiming that TIGHAR *is* correct, but at least they have *something* to support their claim. You have nothing, zip, nada. Maybe you do have some reason you believe that their range calculations are incorrect, but so far you haven't presented it. This is not by any means the foirst time this has been pointed out to you, and your response is always the same; ignore TIGHAR's data and calculations and continue to insist without presenting a shred of supporting evidence, that AE's plane could only reach Gardner in a straight line.

Is this not *precisely* the kind if intellectual dishonesty you purport to be against?

Brian, there was some thought given to the idea that she may have 'made it" to Gardner Island. That is why Naval Aircraft overflew the island: to examine the area and determine if the plane landed there.

However, the Naval Aircraft Crews did not see the plane on Gardner Island, nor did the folks who inhabited the island after Earhart and Noonan disappeared.

You might also consider that TIGHAR has not found evidence of Earhart, Noonan or their aircraft after several "Niku" expeditions.

I would venture to guess, after all this research, the over flights and those inhabitants not mentioning artifacts found that prove Earhart landed the plane on "Niku", that she wasn't there.

David Baker, Sacramento, CA
April 27, 2014 8:54am

Dave Baker, this is what gets me with Niku, Lambrecht {sp?} flew over and didn't see the Electra, tighar would have it that she and Fred were well enough, and the Electra on dry land enough to transmit signals, yet it was close enough to the reef edge to sink from sight a week or so later? Really? They hook on the statement of '...recent habitation...' Lambrecht reported, as if it were proof, all it meant was someone had 'lived' on the island sometime in the observable past, they guy overflew the island and it seems pretty certain if he saw something that even remotely looked like lost aviators he would have investigated further. Fact is, even at the time, when he made his report, his superiors didn't think any more of what he found, surely they would have said: "What do you mean by recent habitation?" or something?

@Kerry Bruhart, I've read Gillespie's book a few times, I think I have a copy of most books on the subject, but his cult seem to suffer from the logical fallacy of an appeal to authority, with Ric regarding himself as THE expert in the subject matter.

I'm not saying we know enough to solve the 'mystery', for sure different fuel figures come and go, but the other appeal to authority -the majority of aviation experts in the field- have a consensus that the Electra could not have got to Gardner on a 'dog-leg' as Brian states in this article...and that is aside from the crazy idea that lost over an ocean one stays on a course for, what, 300 miles? Madness.

Pete, UKIP Wales
May 27, 2014 2:37pm

Pete, the naval flyover should have ended this "Niku" theory. Though some claim signals allegedly made by Earhart were "triangulated" to pinpoint the location of the transmitter in the region of Gardner Island, there was no way to verify that those signals were made by Earhardt, nor that 'triangulation' would be an accurate means to locate the signal origin point in oceanic regions. However, the Navy gave this data some recognition and sent aircraft to check the island.

No traces of Earhart, Noonan or the aircraft have been found on "Niku". The more Gillespie and his people monopolize the funding and sponsorships for conducting these "Niku" expeditions, the less funding will be available to research other avenues.
