Read Jane's Nick Cook's The Hunt for Zero one and mentioned is one Hans Kammler, one of the most camera shy Nazi who started off as a mere (aeronautical?) engineer grad working menial tasks in their Ministry of Works or Labor and rose up the ladder.
The Skoda motor works got involved in whatever secret aerospace projects Kammler was looking at. Also the allied 'T' Forces discovered list as long as your arm with futuristic projects (at the time) either in the planning or experimentation stage found such as lasers to shoot down aircraft, devices to stop enemy vehicles engines from a distance, amongst others.
Nick Cook had gone to Wenceleas Mine in Poland and whatever its called , and discovered what could have been remains of a strange structure that could imply either what was a nuclear reactor or housing / test platform for a saucer shape craft.
Ah its friday night must stop reading too much and head down the pub
