Evidence of wreckage of Amelia Earhart's plane

Last month, a $2.2 million expedition to search for the wreckage of Amelia Earhart's plane on an island in Kiribati finished with what they thought were disapointing results. But since returning to the US, the TIGHAR team has reviewed underwater images they say show a debris field which could be evidence that will solve a 75-year-old mystery.
