Amelia Earhart, the first female pilot to attempt to circumnavigate the world in 1937, was legally declared dead in 1939. Although her remains were never found, it is widely believed that Earhart's mysterious disappearance was caused by a plane crash. However, a new image discovered by The History Channel may prove otherwise. Sean Henry, a former FBI executive assistant director, told Today that in light of the new image, he believes Earhart survived the crash. "When you see the analysis that has been done [on the new photo], I think it leaves no doubt to the viewers that that's Ameila Earhart," he said in the clip ahead.

The remains of Earhart's navigator, Fred Noonan, were similarly never found. But the new photo, taken in 1937, appears to show Earhart and Noonan together on Jaluit Atoll in the Marshall Islands, which were settled by the Japanese until their defeat in World War II. The theory is that both Earhart and Noonan survived the plane crash and were held as prisoners until they died. According to facial recognition expert Kent Gibson, the receding hairline, teeth, and nose of one of the men in the photo matches up with other photos of Noonan. And as for the woman in the photo with the short hair? Well, Gibson says his side-by-side comparison of body measurements proves the possibility of the woman in the photo being Earhart is "very likely."
