gene certainen, of course, was my backup. the funny story about cernen. we were at the point, i think we were approximately four or five days away from liftoff, scheduled liftoff. we were all in quarantine, of course, on the cape. at that time we had to do 21 days before, 21 days after routine, because of the bug stuff. and cernan was out early in the morning flying helicopters. because we all -- the commanders used helicopters to train. and, you know, the last few hundred feet of the landing. so, we're having breakfast, and we knew gene was out flying helicopter. all of a sudden, the door opens, and in walks cernan. he is absolutely covered with soot. he's got scars on his face. we said, cernan, what happened? he had been flying the helicopter over the river which was absolutely calm that early in the morning, like a mirror, and he had been distracted by something or other, because he was looking at the land instead of the water, and he flew that helicopter right into the water. nosed over, blades all over the place, tail, rotor blades all over the place
