In light of the recent whistleblowers coming forward, you have this campy home video interview with Lt. Col. Philip J. Corso basically admitting his knowledge of the existence of NHI and reverse engineering by the US.

Honestly, on what grounds could we not believe the former Chief of Foreign Technology Division of the Department of Defense? What motivation would Corso have to lie about anybody this so late in life?

He also gets right to the point in a manner that to me is telling of someone not really prone to elaboration, ie, lying. Who knows.
