Because everyone knows from Hilly Rose that Bill Clinton lost the war with the space aliens and our last 335 UFOs are hidden beside a lake in Canada. Hilly let that slip while filling in for Art in the late 90s. This guy must have known.
I must be some kind of neanderfuck for not being aware of that.
Ironically, there was an Italian aero engineer who worked on a number of secret German projects in WWII who wrote a book in 1970 where he claimed "flying saucers" were based in the forests of British Columbia. He said the UFOs were British (captured German) craft being flown by the RAF over the US to thumb its nose at the Americans. Seems the Brits wanted the US to share the secrets of the atomic bomb with them, but the US claimed the UK nothing to trade. Turns out they did, the secret saucer craft the Brits found while the US and Russians were busy looking for rocket technology. Like many books on such topics, there was a degree of historical accuracy about German WWII aeronautical research and development.
