When I was with a law firm in Prescott (AZ) in the 1980's, the older partners insisted on using one guy as the court reporter for all depositions because he was so good. He had been contracted by NASA to transcribe transmissions on the astronauts' non-public line on the Apollo moon missions. It sounds extremely low-tech to be using court reporters, but apparently they did. I asked him if he ever heard anything "weird" (like he would've told me!

). He said a couple of astronauts had what sounded almost like emotional breakdowns, but he had nothing to say about what I meant by "weird" (UFOs! aliens!). Edgar Mitchell did have some sort of mystical awakening and went on to found the Institute of Noetic Sciences,

The rumors that the astronauts encountered Someone or Something that convinced them to go away and stay away strike me as far-fetched, but if someone had told me in 1972 that there wouldn't have been another moon landing 54 years later I would have found that equally far-fetched.
