Here are five of the strangest aviation-related crashes and disappearances the world has known:
1. Amelia Earhart
The first woman to fly solo across the Atlantic Ocean, Amelia Earhart disappeared during an attempt to fly around the world in 1937.
She and navigator Fred Noonan were last heard from near Howland Island in the central Pacific Ocean.
In her last known transmission at 8:43am on July 2, Earhart broadcast “We are on the line 157 337. We will repeat this message. We will repeat this on 6210 kilocycles. Wait.”
But nothing more was heard from the American aviation pioneer.
No definitive wreckage has ever been found.
