A grainy sonar image recorded by a private pilot has reinvigorated interest in one of the past century’s most alluring mysteries: What happened to Amelia Earhart when her plane vanished during her flight around the world in 1937? Tony Romeo now believes his new South Carolina-based sea exploration company captured an outline of the iconic American’s Lockheed 10-E Electra. Archivists are hopeful that Romeo’s Deep Sea Vision is close to solving the puzzle — if for no other reason than to return attention to Earhart’s accomplishments.
