NASA-UAP-D6, Apollo 17 Technical Crew Debriefing, 1973
Apollo 17 was the ninth crewed U.S. mission to the Moon, and the sixth to land Astronauts on the lunar surface. This document is an excerpt from the Apollo 17 Technical Crew Debriefing on January 4, 1973, in which astronaut Harrison Schmitt reported seeing light flashes. • Page 24-4. [Lunar Module Pilot Harrison Schmitt]: “We had light flashes just about continuously during the whole flight when we were dark adapted. I had one which I thought was a flash on the lunar surface. That one period of time when we had the blindfolds on for the ALFMED [Apollo Light Flash Moving Emulsion Detector] experiment there were just no visible flashes, although that evening, that night, before I went to sleep, I noticed that I was seeing the light flashes again.”

Way down the tunnel, way back behind, I could see the fireball. CERNAN The only unusual sighting I can recall during landing or recovery -is when the CMP looked out the window and saw the superstructure of an aircraft carrier and said, "Oh, we've got a tin can with us." EVANS Well, it was kind of foggy on the windows. SCHMITT Transearth we had only a small crescent of an Earth and it was not feasible to do any extensive weather observations. We had light flashes just about continuously during the whole flight when we were dark adapted. I had one which I thought was a flash on the lunar surface. That one period of time when we had the blindfolds on for the ALFMED experiment there were Just no visible flashes, although that evening, that night, before I went to sleep I noticed that I was seeing the light flashes again. So, it just seemed to be that one interval either side of it where the light flash was not visible to myself or to the other two crewmen.
