Tonight, National Geographic Channel is airing an all-new documentary called "Hitler's Stealth Fighter."  Apparently in the final months of World War II, American troops discovered a top-secret facility in Germany with an advanced, jet-propelled aircraft like no one had ever seen before.  It was called "The Horten Ho 229."

It was shaped like a massive bat wing... like something out of Star Wars.  But its wooden body was most definitely man-made.  So what did Uncle Sam's army do with it?  Well, they brought back to the United States to be studied, of course.  And everything that they learned about the Third Reich's mystery plane stayed a mystery… until now.

Screen Junkies had a chance to check out an advance screener of the doc, and it's definitely worth watching.  Aside from showing you this prototype of airborne insidiousness inside and out, it also makes you think about what might have happened had Hitler and the Nazis gotten their plane manufactured en masse and into the skies.  It's some scary scheisse.

"Hitler's Stealth Fighter" airs tonight at 9PM ET/PT on National Geographic Channel.
