There was yet another mysterious incident regarding Amelia’s plane. Even though the Lockheed Electra aircraft was never uncovered, a group of explorers did find something which they assumed to be a part of the aircraft back in 1991. Tighar, or The International Group of Historic Aircraft Recovery, discovered the aluminum sheet on Nikumaroro. Tighar’s executive director Ric Gillespie was certain this was a part of Earhart’s plane.
