Nazi Germany built saucer-shaped aircraft, reveals UFO files

A trove of declassified UFO files has suggested that Nazi Germany secretly developed saucer-shaped aircraft capable of reaching speeds of 2,414 kmph and hovering motionless in the air. The documents quoted a man identified as Paul L Peyerl, who claimed the aircraft had a 50-foot diameter. He said he saw it in 1943, two years before World War II ended.
