Amelia Earhart became the first female to fly solo across the Atlantic in 1932, nearly a century ago.
However, just five years after her famous solo flight, the American aviatrix vanished over the Pacific Ocean during an attempt to circumnavigate the globe by plane.
While some researchers who've been on the hunt for what happened to the iconic pilot believe they may have found the wreckage of Earhart's plane at the bottom of the Pacific Ocean, to this day, the mystery behind her disappearance remains unsolved.
Here's what we know: On July 2, 1937, Earhart and her navigator, Fred Noonan, departed from Lae, New Guinea. They were heading for Howland Island, a small island located in the central Pacific Ocean, but they never arrived. By 1939, both Earhart and Noonan were declared dead.
While the case remains unresolved, there are conspiracy theories abound over the late pilot's fate. Here are five of the most compelling guesses behind what happened to Earhart's ill-fated flight.
