hahahah there is no history on the history channel, period.
None, all aliens and other much ridiculous stuff.
Funny you should mention aliens. On the Military Channel of which I now watch regularly, they had a program on Germany’s highly advanced and sophisticated WWII weaponry. After WWII the German scientists came here to the US. The program suggested that many UFO sightings in the 1940s and 50s were the result of new weapons and rockets and spacecraft developed by the German scientists and engineers.
