Here’s what you’ll learn when you read this story:A deep sea exploration group has restored a radio identical to the one used by Amelia Earhart in her final flight. The organization behind the study, Nauticos, has conducted three previous expeditions to try and locate Earhart’s plane. Amelia Earhart’s disappearance in the summer of 1937 has remained one of aviation’s greatest mysteries for nearly 90 years. On July 2, 1937, Earhart and Noonan took off from Lae, New Guinea en route to Howland Island. That’s why Nauticos’ radio experiment could prove crucial.
