"On September 19, 2008 TIGHAR received a request from the television production company that films the PBS series “History Detectives” for assistance in evaluating an artifact alleged to be a piece of Amelia Earhart’s Lockheed Electra. According to a document submitted with the artifact, it was obtained as a souvenir by a member of the U.S. Army Air Corps 50th Observation Squadron at Luke Field, Oahu on March 20, 1937 following the accident that ended Earhart’s first world flight attempt. The serviceman sent the piece of debris home to his mother who received it on April 3, 1937. She kept it 'as a reminder of her admiration for Amelia Earhart.'"
