In July of 1937, Amelia Earhart and Fred Noonan never arrived at Howland Island in the Pacific Ocean, on their trip around the world.

In September, the Deep Sea Vision team, funded privately by Tony Romeo, began scanning 5,200 square miles in search of Earhart and Noonan's Lockheed 10-E Electra aircraft - and they think they have location it.

Their proof are sonar images of a plane-shaped object 16,000 feet down, under miles from Howland Island, where Earhart and Noonan were supposed to refuel.

Will this finally solve the mystery? Lots of planes have gone down in lots of places, and others believe they crashed on or near Gardner Island, a few hundred miles from Howland — and there were reports of radio SOS before the plane went underwater. So only a more in-depth investigation will tell us for sure.
