There is a readers Digest story of an Allied bomber crewman falling, no streamer, no chute at all in fact, nearly 18,000 feet, and landing behind German lines in a marsh.
The german troops in the area found him alive, and upon turning him over to whoever gets prisoners, these Germans declared him PNG, an act of God or whatever, and sent him up through the lines back to Allied forces.
It's been probably 10 years since I've read it, and I never had the interest in WW2 then that I do now, so I'll have to do some checking to find the story.
