Nobody but me seems to have the imagination to understand the ending. The iceman doesn't fall from the helicopter. At first he seems to but then he ascends into the sky. The moral of the story is that the doctors and scientists think that they'll make a fantastic medical breakthrough by callously using the iceman to understand how he survived being frozen. The think that they'll find a way to prolong peoples lives through cryogenics. The ending shows that if they had learned about his spirituality and his religious beliefs he could have taught them the way to eternal life.
