I'm not persuaded we made alien contact in 1947--I'm not convinced the evidence from Roswell is sufficient to conclude that. However, the government was certainly interested in widespread reports of unidentified aircraft at that time--not just at Roswell but all over the country and even abroad--and these reports were actually viewed in the context of the Cold War by the military and the intelligence agencies. There was concern that the Soviets might have gotten an edge in extrapolations from German wartime aircraft/rocket advances (there had also been UFOs of various types spotted during the war, notably the foo fighters), which was particularly alarming because there was a high concentration of UFO sightings around US nuclear research facilities, plus the Japanese were known to have attempted to use balloon bombs as bioweapons during the war (fortunately they didn't work). There was also concern over the Soviets exploiting UFO panic for propaganda purposes, as some of the leaders of the citizens' UFO groups had Communist associations (as some still do IMO--I'm quite suspicious of the the Disclosure Project because it seems to have an anti-SDI agenda and to be oriented towards getting into files on classified US/UK military research). There is some interesting discussion of the FBI's investigation of early UFO sightings in:
Bruce Maccabee, UFO/FBI Connection
As a sort of "barf alert" note, I'll that Maccabee's political perspective seems to be a bit different than mine and I'm interpreting some of the documents he discusses differently than he does. Nonetheless, the documents he discusses are quite interesting, particularly if you're familiar with some of the military and scientific figures he mentions. Some of the scientists assigned to investigate UFOs were also prominent in atomic research, and a few of them also come up in discussions of Soviet espionage at that time.
Understandable perspective.
I guess at this point--and, for several years, really, I've accepted as fact that there were "ET" bodies and probaly one survivor at Roswell.
I've read the pros and cons for decades but that's how I've come down. And, given the increasing death bed testimonies, I've only strengthened that conviction.
I think Greer is delluded that ET's are benign and harmless. I don't trust the puppet masters either by a longer shot. I see it all as being used of satan to usher in the Biblically predicted world government. Nothing else makes sense. But what that means about what races; what percentages of the whole ET panorama will end up on the side of evil--should be interesting. It seems to me at present that a lot of them will be--I expect more than 90% of them will be on the side of evil.
I think we already have more SDI type stuff already deployed but under the firm grip of the puppet masters than a lot of people could conceive of existing.
I ran across one supposed senior military type recently retired or some such who asserted rather startlingly that we were 50 years ahead of everyone else in arial craft and actually, that in terms of technology--if it could be imagined, we could do it. An incredible statement when one considers SG-1.
