German scientist Von Braun was at Roswell during UFO crash

Dr. von Braun explained how he and his (unnamed, for now) associates had been taken to the crash site after most of the military were pulled back. They did a quick analysis of what they found. He told me the craft did not appear to be made of metal as we know metal on earth. He said it seemed to be created from something biological, like skin. I was lost as to what he indicated, other than thinking perhaps the craft was "alive."
