Thanks for posting this. There's a widespread belief uttered by the snearing crowd that UFOs are reported to only land in the boonies and abduct rednecks, and if UFOs were real, they would land on the White House lawn.
As one of the snearing skeptics, I will however admit that the mass wave of UFOs over D.C. in the 50's and the more recent report by multiple witnesses around the Brooklyn Bridge, including the U.N.'s SecGen at the time, of a woman being floated out of her 10th story apartment into a hovering disc, tends to quash the fallacy that UFO sightings are a Cletus The Slack Jawed Yokel phenomenon only.
For my own part, I have seen a hovering boomerang over I-84 I believe that, based on the work Dr. Brown was doing 50 years ago, we do have military aircraft capable of hovering silently, and which use gravitics, rather than conventional thrust propulsion, to get around.
We'll probably find out about them in another 10 years, just as we found out about the SR-71 only in the 70's, and the F-117 in the 90's.
Whether all UFOs are attributable to black military projects, I don't know. If it's a holographic universe, then anything is possible.
