Amelia Earhart's plane may have been found.

It's the $1 million Timothy Mellon kicked in for the latest search that he thinks has gone missing.

The son of late philanthropist Paul Mellon is suing The International Group for Historic Aircraft Recovery, claiming it hit him up for the money last year knowing the wreckage from the 1937 flight had been found underwater two years before.

A Mellon attorney says experts examining 2010 photos came to a "definitive conclusion" that it was the Earhart plane, but TIGHAR lawyer and searcher Bill Carter disputes profiting from hiding the discovery. "Just the opposite," he said, "we would want to publicize the finding to ensure that we can protect it adequately."
