Possible clues to Amelia Earhart's disappearance

A team of researchers detected an anomaly on the ocean floor near an island in the south Pacific where historians believe Amelia Earhart may have disappeared in July 1937 during her quest to circumnavigate the globe by plane.

Ric Gillespie, executive director of The International Group for Historic Aircraft Recovery (TIGHAR), said his team believed Earhart landed her plane on the island of Nikumaroro, about 2,000 miles southwest of Hawaii, and that the plane was swept to sea with rising tides.

Using underwater sonar, the team discovered an anomaly about 22 feet long near the island and believed it might be a section of Earhart's Lockheed Electra, which was 38 feet long.

TIGHAR has received approval for further research and investigation into the discovery, and though the development is promising, Gillespie suppressed his excitement and said it could end up just being a section of coral reef.
