It was the 1940s and the allied air campaign was in full swing over Italy. German forces were entrenched around a small church and five allied bombers went in for the bombing run. All five planes malfunctioned after seeing what appeared to be a man in a black outfit hovering in the clouds waving the planes away.
The pilots turned around and flew in for a second run, saw the mysterious hovering man again, and again all five planes malfunctioned and the bombers returned home still fully loaded.
