If you want my take on it...
They probably do not blast off like old times. If one dives deeply
into the UFO stuff-Nazi's and all, the anti-gravitic propulsion
has come a long way. Heck, I met a fellow Security guard(my source
of income) that worked at 51 (so he calls it) that has gone up in
a saucer. And let me tell ya, if that old arrogant SOB has gone
up in one I wouldn't doubt that there are "missions" going all over
the place determining engineering limits, etc. of the technologies
being perused by the various adjendas. No big deal. UFO Disclosure
is the answer to that-may GOD speed(coffee, please.)
