HERE IS THE PROGRESSION of the building of the "Haunebu". The German WWII Black Sun organization started building the Haunebu Flying Discs in about 1940 -1941 and before that is was the Vril. The two Haunebu IV was finished in 1945, and one was sent to Mars. They knew it was a one way trip, and no one knows if the craft was heard from again. The German war machine made 163 known Flying discs, and most were flown out to Antarctica and South America before the end of the war.
