The 1941-Cape Girardeau, Missouri Crash story is related by one Charlotte Mann, whose grandfather was a Reverend. He was called out on a "plane" crash, and after arriving at the scene, he discovered he was misled about what had really crashed. It was actually a UFO, and he was even asked to pray over dead alien bodies.
This case was first brought to investigators by Leo Stringfield in his book "UFO Crash / Retrievals: The Inner Sanctum," and is a mystery that I have worked on for years to obtain more information about, but it has been a tough nut to crack. Read the accounts linked above, and tell me what you think about it.
