HONOLULU - A team of researchers trying to solve the mystery of aviator Amelia Earhart's 1937 disappearance said on Friday that underwater video from a Pacific island has revealed a field of man-made debris that could be remnants of her plane.

The footage was collected in July by The International Group for Historic Aircraft Recovery (TIGHAR) during a $2.2 million expedition to Nikumaroro in the Republic of Kiribati.

Unsolved questions about Earhart's fate have long heightened her legendary status as a pioneering aviator, and TIGHAR's voyage to seek clues in her disappearance gained interest far beyond the shores of the remote island where the team searched.

The search was plagued by technical issues in what researchers described as challenging ocean conditions off the Nikumaroro reef, where they believe Earhart's plane landed and was then swept away into the sea.
