He isn't an idiot and he isn't crazy.
So that leaves 2 options: He's either lying OR he's telling us what he believes to be the truth. I say "what he believes to be the truth" because there is a chance that, even with his scientific pedigree, he is somehow mistaken. BTW, he is one of many scientists who say they are working with exotic material from "crashed" UFOs. I didn't say this...he did.
As an aside, his statement isn't new. He and other scientist have been saying this for a short while now. Some folks call his comment the first announcement of "disclosure."
What do I think? I think I'll wait and see what comes next.
BTW, the general consensus from that part of the scientific community that is involved with this matter is that the Pentagon will NEVER disclose anything related to UFO/UAPs. The DOD isn't in the business of "disclosing" anything.
Then let him produce one!
You left out a third option !
He could be crazy!
