In his ten trips to Nikumaroro, Gillespie has brought back a rusted pocket knife, bottles, zippers and pieces of a shoe, any of which could have belonged to Earhart and Noonan, but also to the people who lived on the island between 1939 and 1963. Gillespie and Elgen Long have been arguing for decades over the piece of aluminum found there. Long says the piece obviously comes from the wing of a PBY, a U.S. military seaplane. “I think if Ric proved anything, it’s that [Earhart and Noonan] never were close to that island,” says Tom Crouch, senior curator of aeronautics at the National Air and Space Museum. “Otherwise he would have found something definitive. Ric is in the business of taking wealthy people on an archaeological adventure, Indiana Jones-style.”
