For decades, pioneer aviator Amelia Earhart was said to have “disappeared” over the Pacific on her quest to circle the globe along a 29,000-mile equatorial route. Now, new information gives a clearer picture of what happened 75 years ago to Ms. Earhart and her navigator Fred Noonan, where they came down and how they likely survived – for a while, at least – as castaways on a remote island, catching rainwater and eating fish, shellfish, and turtles to survive.
