It has been 72 years since famed aviator Amelia Earhart and navigator Fred Noonan disappeared while attempting to fly around the world. But the mystery remains unsolved: Nobody knows exactly what happened to Earhart or her plane.
Now researchers at the International Group for Historic Aircraft Recovery, or Tighar, say they are on the verge of recovering DNA evidence that would demonstrate Earhart had been stranded on Nikumaroro Island (formerly known as Gardner Island) before finally perishing there.
