If TIGHAR’s approach to scientific inquiry does not fit the accepted mold, then what would it look like for the group to hold itself to the same standards as other scientists? Rebecca Ackermann, an archaeologist at University of Cape Town in South Africa, identifies the first major obstacle: “Ideally a study of the skeleton would include the skeleton,” she tells Popular Science. Due to poor record keeping back in the 1940s, the skeleton that Gillespie and his associates at TIGHAR suspect to be Earhart’s has not been seen in decades. Therefore, their analyses have all been performed with measurements taken by D.W. Hoodless of the Central Medical School of Fiji. When the bones were first discovered, Hoodless proclaimed that they belonged to a man, so no one jumped at the opportunity for evidence in the Earhart cold case. As far as anybody knows, they’re still lost.
