UFO's? I thought Adolf Hitler was more interested in occult artifacts like the
Ark of the Covenant, the
Holy Grail, and the
Spear of Destiny? Or, barring that, objects from
Odin's treasure room in
Asgard to reinforce his image as a descendant of the gods?
Then again, some people believe that those artifacts are of extraterrestrial rather than occult origin.
But I have to admit: programs like that are fun watching as long as you take the theories expressed by those taking part in it with a healthy dose of skepticism and imagination.
