The "crackpot" makes a logical statement

: "Such a policy, of course, is directly due to 'Brookings' -- the official NASA report of almost 50 years ago (1959) -- which warned the U. S. Government that any scientific evidence of extraterrestrial intelligence 'could be destabilizing to terrestrial governmental institutions, if not the future of civilization ... '"

This is logical. I don't know how many people here are aware of the panic induced by the radio airing of "War of the Worlds" back in the 1930's, but that would be a test case proving that what the web author (and NASA in general) had said would be true--the official announcement that we are not alone could prove disastrous.

Ignorance is bliss, as they say. And considering the herd mind of humans, I wouldn't be surprised if everyone went in a mass panic if the government DID say, "Yep. There are aliens out there." So they keep it hush-hush.
