Researchers with TIGHAR now theorize that Earhart and Noonan crash landed just offshore from deserted Gardner Island in the Pacific, essentially becoming castaways, and spent days sending out radio messages, including pleas for help, in the hopes of being rescued, and plenty of people heard those broadcasts.
They could only use the radio when the tide was low, TIGHAR researchers theorized, because their Lockheed-Electra aircraft had crashed just offshore, so they only had a few hours every night to broadcast their whereabouts.
Director of TIGHAR, Ric Gillespie, told the Washington Post it wasn't enough, and that he believes Earhart and Noonan died as castaways on Gardner Island.
The theory that the radio messages were heard by dozens, though, runs counter to the official U.S. Navy account, which maintains the pair died after crashing into the Pacific short of Howland Island.
Gillespie says the Earhart and Noonan radio messages form a historical record, and that people just happened to be listening to their radios when they heard Earhart's cries for help, according to the Post.
Here's what the Post reported TIGHAR discovered in its research:
“Scattered across North America and unknown to each other, each listener was astonished to suddenly hear Amelia Earhart pleading for help. They alerted family members, local authorities or local newspapers. Some were investigated by government authorities and found to be believable. Others were dismissed at the time and only recognized many years later. Although few in number, the harmonic receptions provide an important glimpse into the desperate scene that played out on the reef at Gardner Island.”
Not only did naval vessels searching for Earhart hear some of the radio transmissions from Earhart and Noonan, but so did average people including Nina Paxton, the Post reported.
Paxton, from Ashland, Kentucky, said she heard a broadcast from Earhart on July 3, 1937, a day after the aviator disappeared.
She heard Earhart say “KHAQQ calling,” and she heard her say she was “on or near little island at a point near” … “then she said something about a storm and that the wind was blowing.”
“Will have to get out of here,” Earhart said at one point, Paxton recounted. “We can’t stay here long.”
Despite the radio evidence, and other evidence collected over the years, there’s still no definitive answer on what really happened to Amelia Earhart.
