Apollo Astronaut Speaks on UFO, Alien Claims : Discovery Cha
- Apollo astronaut Edgar Mitchell returned from his mission to the moon a changed man. He has spent the last 35 years trying to use the tools of science to figure out what happened. Along the way, he says that people knowledgeable about an alleged crash of an alien spaceship in Roswell, N.M., shared the information with him. He's been speaking out ever since, most recently on a radio talk show that tripped off an unexpected wave of media attention. In a telephone interview with Irene Klotz, Mitchell sets the record straight -- as he sees it.
