2 July 2012 Last updated at 07:35 BST

An operation is set to begin off the coast of Hawaii to try to find out once and for all what happened to the American pilot Amelia Earhart.

Researchers will use an underwater robot equipped with sonar and high definition cameras to try to prove their theory that, on 2 July 1937, she crashed near a remote Pacific Island.

The BBC's Stuart Hughes reports.
