Amelia Earhart Survived. Here’s What the Evi...

Amelia Earhart Survived. Here’s What the Evidence Shows.

Last month, the US government declassified over 4,000 documents about Amelia Heheart’s disappearance.

You’d think after 88 years, we’d finally get answers.

We didn’t.

The release was a complete dud.

But while everyone focused on those files, there was another source sitting in plain sight.

Take a look at this.

When the New York Times covered the declassification, they quoted Richard Gillespie from the International Group for Historic Aircraft Recovery, otherwise known as Tiger.

Quote, “A lot of the really good stuff on Airheart is not in the National Archives.

We have found it in other places and we put it up on our website.

” End quote.

So, I took a look.

Tens of thousands of pages, original radio logs from the USS Itasa, Navy search reports from 1937, forensic analysis, documents publicly accessible for years.

And when you read the primary sources, not the headlines, but the actual evidence, what emerges isn’t a mystery.

It’s a tragedy, a preventable one.

Because here’s what actually happened.

On July 2nd, 1937, the USS Itasca lost contact with Amelia Heheart at 8:43 a.

m.

That’s the official story.

But other radio stations hundreds of miles away kept hearing transmissions for days.

Transmissions that suggest she didn’t crash into the ocean at all.

So, I think it’s time to talk about what the radio evidence actually tells us.

First, some context.

There are two facts that most people don’t know about Amelia’s final flight.

First, this was Airheart’s second attempt to circumn the globe.

Amelia Earhart - American aviation pioneer (1897-1937) – Torgoen

Secondly, there was actually supposed to be two navigators on Amelia’s flight around the world.

Fred Nan and a man named Harry Manning.

On Hehheart’s first attempt to fly around the world, Manning was present in the plane in addition to Nunan.

But very famously, Hehheart had a landing gear collapse during takeoff in Hawaii.

The plane was loaded with nearly 1,000 gallons of fuel.

By all accounts, it should have exploded, but it didn’t.

That was nothing short of a miracle.

After the Hawaii crash, Manning backed out.

He didn’t want to risk his life again.

This incident happened in March of 1937 and delayed Hehheart’s circumnavigation attempt until she could try again a few months later, during which she and Nunan ultimately disappeared forever.

Manning was crucial because he was the only one of the three who was actually skilled in radio communications.

When he found out Hehart was planning a second attempt with only Nunan, Manny was immediately worried.

Here’s why.

Neither Hehart nor Nan had mastered Morse code.

They both preferred voice communication because it was easier.

But here’s the problem.

Voice signals fade.

They get garbled by static.

While Mars code that cuts through interference and bad weather, no problem.

In a life or death situation over the Pacific, that difference matters.

And Manning wasn’t the only one who was concerned.

Eleanor Smith was the youngest licensed pilot in the United States at just 16 years old.

In 1929, she flew with Hehheart during a test flight in Delaware.

At one point, Hehheart took over the controls from the test pilot.

The plane immediately started lurching and wobbling.

Embarrassed, Hehheart signaled for the test pilot to take back control.

Years later, Smith recalled in a memoir, quote, “She knew the basics, I guess, but she didn’t have that much practice.

as sure as God is my judge, she could not keep her nose on the horizon.

” End quote.

After the Hawaii crash, Hehheart’s husband, George Putnham, didn’t have enough money to fully repair the plane.

To save on cost, they scaled back on modifications.

Stronger radios scaled back.

Better direction finding equipment scaled back.

Emergency gear scrapped.

Before her second attempt, Hehart gave an interview to a reporter named Alan from the Herald Tribune.

He asked her why she wanted to do this and her answer was premonetary.

Quote, “I have a feeling that there is just one more good flight left in my system, and I’m hoping this trip is it.

I’ve only got one obsession, a small and probably typical feminine fear of growing old, so I won’t feel completely cheated if I fail to come back.

” End quote.

She asked him not to publish this interview until after the flight.

While waiting, Allan did some digging into what had been done to prepare the plane.

And he noticed something critical was missing from the equipment checklist, the marine frequency radio.

This was the device that lets you send distress calls to ships.

When he asked Hehart about it, she called it dead weight and reminded him that neither she or Nunan knew much Morse code anyway.

Better to leave it behind.

These were warning signs that all pointed to the same problem.

Hehheart didn’t understand her radio equipment well enough to use it when things went wrong.

And she was about to attempt the most dangerous leg of her journey.

2,500 m of open ocean with almost no margin for error.

The flight from Lelay New Guinea to Howland Island was always going to be the hardest part of the journey.

The Pacific Ocean is massive.

Most planes in 1937 had a range of only a few,000 km.

Airheart’s modified Loheed Electra could fly about 6,600 to 7,200 km in perfect conditions.

So the night before on July 1st, Airheart and Nan stripped the plane of any unnecessary weight.

Airheart removed the insulation, making the engine so loud that they had to communicate by passing written notes on a bamboo pole.

Nunin left the smoke bombs meant for a sea rescue under his hotel bed.

Every decision was about shaving ounces to extend range, but in doing so, they eliminated the redundancies that could have saved their lives.

These series of errors turned what should have been a difficult but achievable flight into something impossible.

Theoretically, Hehheart could fly straight to Lelay to Hawaii, but perfect conditions rarely exist over the Pacific.

So, the game plan was to stop at Howland Island, a tiny strip of land about 2 km long and less than a kilometer wide, sitting roughly halfway between Australia and Hawaii.

Finding it from the air would be like trying to spot a grain of rice.

So, the navigation plan relied on two methods.

Celestial navigation using the sun, moon, and stars to calculate position and dead reckoning, which calculates how long it should take to reach the island based on your speed and direction.

Airheart and Nan calculated it would take about 18 hours to reach Howland.

But 20 minutes into the flight, Lei radioed a warning.

Headwinds were stronger than expected.

Airheart didn’t acknowledge the message.

More on why later.

This matters because headwinds change your travel time and celestial navigation alone isn’t accurate enough over such long distances.

Small errors can add up.

In fact, this already happened earlier in the trip when Hehart and Nunan flew 12 hours across the South Atlantic to Sagal.

They ended up landing more than a hundred miles away from their intended destination of Dhakar because of small calculation errors by Nunan.

So to help them along in their most difficult leg of the journey, three US Navy and Coastg Guard ships were positioned strategically along the route.

The USS Ontario halfway between New Guinea and Howland.

The USS Swan between Howland and Hawaii.

And the most important one, US Coast Guard Itasa, which was stationed right by Howland Island.

These ships were supposed to act as radio beacons, like lighouses that Hehheart could home in on using her direction finder.

The Itasca was also supposed to send up smoke signals when she got close to help her spot the island.

But this is where everything started to go wrong.

Between Miami and that final takeoff from Lei, Airheart made three critical mistakes.

Each one survival on its own, but together proved fatal.

In late June, while Hehheart was in Java, a radio specialist sat down with her to plan the beacon frequencies for the three ships.

His plan expressed in wavelengths was Ontario 750 m, Swan 900 m, and Itasca 750 m.

These were perfect frequencies for Airhart’s loop antenna direction finder.

But here’s the catch.

In 1937, radio waves were described in two different ways.

You could express them as wavelength in meters or as frequency in kiloycles or kilohertz as we call them now.

The specialist was speaking in wavelengths.

So Airheart needed to convert them into frequencies.

The math is straightforward.

Wavelength time frequency equals speed of light which is a constant.

So 750 m equals 400 kHz.

900 m = 333 kHz and so on.

But on June 27th, 1937, Hehheart sent this message to the ships.

Ontario 400 kHz, Swan 900 kHz.

She used the wavelength number without converting and Itasa 7.

5 mega cycles or 7,500 kHz, which is catastrophically wrong.

Ultimately, Airhart appeared to mix up the wavelength and frequency.

Now, why does this matter? Loop antennas like the one on Airheart’s plane can only take accurate bearings on frequencies up to about 1,800 kHz.

So, by specifying 7,500 kHz for the Itasa, the most important beacon, she asked them to broadcast on a frequency more than four times too high for her equipment to work.

However, in her message, Hehheart said that if the frequencies were unsuitable, she should be informed.

But nobody on the Itasca questioned it.

They just assumed she knew what she was doing.

So Itaska turned up its transmitter to 7,500 kHz and waited for a message that would never arrive.

That was mistake number one.

But weeks before this moment, Airheart had already made another decision that would prove just as catastrophic.

In late May, when Airheart reached Miami, she had the trailing antenna completely removed, a 250 foot wire used for Morse code transmissions on 500 kHz.

Since neither she or Nan were proficient in Morse code, she considered it once again dead weight.

But what she didn’t understand was that by removing this antenna, she eliminated her ability to communicate with ships on 500 kHz, the one frequency the ship’s direction finders could actually use to locate her.

With only the tiny fixed antenna on top of the fuselage, her transmitter could radiate only about a half watt of power.

For context, that’s less than a Christmas light bulb.

She was essentially trying to communicate across the Pacific Ocean with the radio equivalent of a whisper.

The short antenna also caused another problem.

It created a mismatch with the transmitter that made her voice sound distorted and hard to understand.

What operators described as over modulated.

There was supposed to be a backup.

A direction finder had been set up on Howland Island specifically to take bearings on Airheart’s 3105 kHz transmissions.

That direction finder also used a loop antenna which just like hers couldn’t accurately track frequencies above 1,800 kHz.

Everyone involved thought it would work because they didn’t fully understand the technical limitations of the equipment.

So that’s two critical failures.

But remember Harry Manning, the radio expert who backed out? He’d warned Airheart about the third mistake from the very beginning.

By choosing to rely entirely on voice communication, Hehheart eliminated her most reliable backup system.

In the high static environment of the tropics with a weak antenna and an over modulated transmitter, this would prove to be a grave error.

Okay, now back to the video.

Okay, now let me walk you through what actually happened on July 2nd, 1937 using the radio logs and timestamps.

About 7 hours into the flight at 7:20 GMT, the Itasca started hearing her transmissions, but could barely make out what she was saying.

They tried calling her back numerous times.

She never responded.

This suggests her receiving system had already failed.

The most likely explanation is that lightning or static discharge damage what’s called the send receive relay.

A switch that connects the antenna to either the transmitter when you talk or the receiver when you listen.

If it got stuck in transmit mode, she could send, but she couldn’t hear anything coming back.

9 hours in, Heart expected to pass the USS Ontario.

She listened for Morse code ends on 400 kHz, but heard nothing.

The original plan was for the Ontario to wait for Airheart to request transmissions, but without the trailing antenna, she could only send high frequency signals and not the low frequency needed to contact the Ontario.

Realizing her problem, Hehart sent an urgent telegram asking the Ontario to start transmitting every 10 minutes, but the message didn’t reach them in time.

at A15 GMT about half an hour later.

Quote, “Please take a bearing on me now and report it to me in half an hour.

We’re about 100 miles out.

” End quote.

Airheart likely meant to say, “On the half hour rather than in half an hour.

” Then at 1912 GMT, Itasa receives the transmission that makes your stomach drop.

Quote, “We must be on you now, but can’t see you.

Running out of gas.

Only 1 half hour left.

been unable to reach you by radio.

We were flying at 1,000 ft.

” End quote.

This is where you can hear the panic setting in.

The Itasco was right there, transmitting so powerfully that even San Francisco picked up their signal.

Airheart signal was coming in loud and clear to the ship, but she couldn’t hear anything from them.

She thought the radio had completely failed, and she only had 30 minutes of fuel left.

At 1925 GMT, Hehheart tried something different.

She tried to home in on the ship’s beacon herself.

Quote, “We are circling but cannot hear you.

Go ahead on 7500 now.

We’re on the schedule time on half hour.

” End quote.

She was asking them to activate the beacon at 7500 kHz.

The Itaska immediately started broadcasting Morse code A on that frequency and Airheart responded right away.

We received your signals on 75 but unable to get a minimum.

Please take bearings on us and answer 3105 with voice.

End quote.

Okay, let me explain what unable to get a minimum means because this is the crucial moment.

When you use a loop antenna for direction finding, you rotate it in a circle.

The signal gets louder, louder, loudest, quieter, quieter, then silent.

That silent point, the minimum or null, tells you the direction the signal is coming from.

Airheart could hear the beacon clearly, but when she rotated her loop antenna, she couldn’t find that null point.

She couldn’t get a bearing.

Why? Because again, 7500 kHz was far too high for her loop antenna to work properly.

She was literally listening to the signal that could save her life, but her equipment couldn’t tell her which direction to fly.

And here is the cruel irony.

There was a workaround.

There was a switch in the cockpit that could have bypassed the broken relay.

She could have manually switched the receiver to use the loop antenna while keeping the transmitter on the fix antenna.

If she had done that, she would have heard the Itaska’s voice transmissions, but unfortunately she didn’t know her equipment well enough to try it.

At 2013 GMT, Airheart transmitted her final message.

Quote, “We are on line 157 337 running north and south shifting to 6210 kilycles.

” End quote.

This was a line of position.

Airheart was telling them she was flying along the navigation line, but didn’t know where on the line she was.

Then she switched frequencies to 6210 kHz.

And that was the last time the Itasca heard from Amelia Heheart.

But the Itasca wasn’t the only station listening.

Right after Hehart’s plane went missing, the US Navy put out an urgent bulletin.

Listen to frequencies 3105 and 6210 kHz.

Those were Airheart’s channels.

Her plane’s radio was only designed to work within a few hundred miles, but radio waves can bounce off the ionosphere and travel thousands of miles if you’re listening at exactly the right time.

And some people were.

A 15-year-old girl in St.

Petersburg, Florida, frantically transcribed what she heard.

Water’s high.

Water’s kneede.

Let me out.

Help us quick.

A housewife in Toronto.

We have taken in water.

We can’t hold on much longer.

Nina Paxton in Kentucky heard Airheart’s actual call sign KH AQQ followed by we’ll have to get out of here.

We can’t stay here long.

The Coast Guard and Navy logged 120 known reports.

Most were dismissed as hoaxes or static, but Tiger went back through those logs and found 57 reports they consider credible.

All recorded between July 2nd and July 5th.

But there was something strange about these transmissions.

Tiger analyzed the signal strength from all of them.

Only Baker Island, the station closest to Gardener Island, heard clear voice signals with Airheart’s call sign.

Every other station just picked up what’s called a carrier wave.

You know someone’s transmitting, but you can’t make out the words.

In other words, the farther from Gardener Island, the weaker the signal got.

And if you notice, the island just above Baker is Howland Island, the very same island that Hehheart and Nan were supposed to land at to refuel, but never arrived.

And eerily enough, Hehart’s final radio message to the US Coast Guard vessel at 8:43 a.

m.

was her stating that she was on the line of position 15737 running north and south.

And what other island happens to be on this line of position? Nikamora Island, also known as Gardener Island.

But here’s what’s even stranger.

The messages came in at odd times, not continuously, but in a specific pattern.

When Tiger mapped those transmission times against historical tide data for Gardener Island’s reef, they found something striking.

Every single credible transmission occurred during low tide.

But why would that matter? Here’s the hypothesis.

If the plane was partially submerged on the reef, Airheart would have a problem.

Her radio needed the plane’s battery, but so did the engine starter.

She couldn’t just leave the radio on, otherwise she drained the battery and never be able to restart the engine.

But if the engine was in the water, she couldn’t run it at all.

She’d have to wait until low tide when the propeller cleared the water, then start the engine to power the radio to send out a message.

That would mean Airheart and Nunan were stuck on a schedule dictated by the ocean, seeking shelter during the day, returning to the plane at low tide to try the radio again.

If true, this means they survived the crash and were alive for at least 3 days, waiting for rescue that never came.

But if Hehheart made it to Garder Island, there should be physical evidence.

And 3 years after her disappearance, someone found it.

In 1940, a British officer named Gerald Gallagher found human bones on Gardener Island along with a woman’s shoe, a sex tint, and a jar of 1930s era freckle cream.

The bones were examined by a doctor in Fiji declared to be male and discarded.

This wasn’t unusual for the time.

Forensic osteology, or the study of bones, barely existed as a discipline.

But it means we can’t do a DNA analysis.

The bones are gone.

But what we do have are the measurements.

In 2018, forensic anthropologist Dr.

Richard Jans reanalyzeed the original measurements using a modern program called Forisk, a software that estimates sex and ancestry from skeletal dimensions.

It’s widely used by forensic anthropologists today, though it has its fair share of critics.

Jance compared the bone measurements to Hehart’s known measurements from photographs and her pilot’s license.

His conclusion, the bones matched Hehheart’s proportions more closely than 99% of individuals in his reference sample.

Now, what’s interesting is that Gallagher wrote in his report that the bones were also found near remains of fires, turtles, and dead birds.

Signs that whoever died there has survived for quote some time.

I want to be clear, none of this is definitive proof.

The bones are gone.

The plane hasn’t been found.

But here’s what we know for certain.

Multiple people reported hearing distress calls days after the Itasca lost contact.

Documented by both the Navy and Coast Guard.

Garner Island sits on that 15737 line of position from Airheart’s final transmission.

Human bones were found there in 1940.

Modern forensic analysis suggests they could have been heharts.

Does that solve the mystery? No.

But it suggests something far more haunting than a quick crash into the ocean.

That Amelia Heheart made it to land, survived, and sent desperate messages while the world searched thousands of miles away.

She died waiting for someone to hear her.

Before her final flight, she told that reporter she had one more good flight left in her, and she was right.

But it wasn’t the flight she planned.

88 years later, we’re still trying to bring her home.

Look, I know what you’re thinking.

If Tiger has all this evidence from 30 years investigating, why hasn’t the mystery been solved? I had the same question.

So, I flew to Pennsylvania and asked Richard Gillespie directly and had him show me everything.

the artifacts, the expedition footage, the forensic analysis.

And I asked him the hard questions.

Why hasn’t the plane been found? What do you say to people who think you’re wrong? And what convinced you after all these years that you’re even searching in the right place? His answers are next.

You don’t want to miss that.

Thanks for watching.
