Most people today are familiar with History Channel's "Ancient Aliens" series and other assorted pseudo-history programming; however, this sort of thing has been around for a long time.
This particular example of woowoo dates from 1975, and it certainly won't disappoint. It has UFO's, ancient astronauts and the Bermuda Triangle. I recommend it, not for it's insightful themes, or revelations of hitherto unknown knowledge, but rather as something of a guilty pleasure. If you've seen "Chariots of the Gods" and other assorted TV programs, or if you're curious as to where TV programs such as the aforementioned "Ancient Aliens" got their start, hopefully you'll find this particular example of such things entertaining.
