David Adair was a child prodigy in the realm of engineering. At 17 years of age he became what is probably the youngest ever "rocket scientist". Since the end of the Cold War he has joined Stephen Greer's Disclosure Project and has come forward with a startling revelation: He was involved with Black Budget projects relating to Area 51 and UFO's in the 60's and 70's. He has had contact with a device that covers the realms of both machine and living alien! This is very rare indeed.
I find his testimony very compelling. It's hard to see what he could gain from making this up. Unlike Bob Lazar, he has no need of sensationalist "fame claim". His work in rocketry and jet engines was prestigious enough.
