Final Conclusions

The aluminum sheet with the “ALCLAD” marking, allegedly from Amelia Earhart’s Electra aircraft, is actually from a 1940s aircraft — precisely as the aluminum markings predicted. The artifact’s unique rivet pattern matches exactly the top of the wing of a surviving Douglas C-47B Skytrain built in the 1940s. (This is especially significant since a C-47 crashed on Sydney Island in the Phoenix Group.)

Case closed.
