>but it wouldn't surprise me if a bulk load of ufo sightings were black projects being tested.

Sure, I'd bet a lot of "black triangle" sightings are exactly that. But if the "tic-tac" lore is to be taken at face value, the implication is that the US military has invented antigravity technology, or reverse engineered it from alien spacecraft. I really don't think that's plausible. If the US had that kind of technology we would be so far ahead of the rest of known science that there would be no value in keeping it secret.
