Let me help you fellas out here.
The '70-'71 research project you're referring to was the genus of Expanded Dianetics which supposedly handled, amongst other things, "psychosis". It involved may a couple of dozen Cases at the very most. There were virtually no public on board the Apollo during that time. I have no knowledge of the Fenninger incident you cite.
The "Introspection Rundown" which supposedly handled "psychotic breaks" and ended the need for Psychiatry was almost solely based on one Case in Dec. '73-Jan, which happened to be that of a 19 year old Flag Officer named Lt. Geoffrey Quentin McCaully Hubbard. '74.
