J.E.Hoover was once misinformed by his agents about "Death Star" idea as it was done blueprint. Believing it to be in national interest, he ordered confiscation of that work of Tesla. Since Hoover's storm-troopers had no clue what they are looking for, they boxed all of research papers (as well as decorative trinkets and even wall-paintings) they found in laboratory as well as in apartment of deceased scientist.

That plain misinformation later gave rise to notorious theory of "30-40 crates of Tesla's files stolen by G-men". Papers were forgotten until they returned to focus few years ago, ended declassified and made public - by that time, the conspiratorial mythos has already rootedin and bloomed up to that degree that just about every piece of advanced tech that appears can sooner or later be tied to fictional "missed crates" and "Tesla tech".
