ON a previous trip they found an aluminum panel in the lagoon that matched up about 90% with one the panels of a Lockheed Electra.
They couldn’t make a definative match because of a rivet pattern differing slightly or something, but the difference was explainable through repairs or something — but (always another but in this story) there was also no proof that repair had ever been made to the plane Earhart was flying.
Wish I could remember the whole story, it was from 4-5 years ago I think. Same group too I believe (Gillespie)
