On an October 1972 visit to the offices of NICAP, Vallee met John L Acuff. "Acuff had a letter from Sturrock on his desk, so he asked if I knew him, which showed how uninformed he was. I urged him to cooperate with Peter's project." (p.159.)
Feb 1973. "Over lunch with Sturrock and Harder on Thursday I was finally able to see and touch the famous sample of tungsten silicate that got Allen so excited he wanted to start a new company." (p.180.)
March 1974 saw a joint meeting of the AIAA's UFO sub-committee and Cufos. Present was Peter Sturrock. "Sturrock suggested organizing a workshop of academics at Aspen. We spoke of international cooperation. " (p.241.)
Aug 1974. "A symposium on UFOs and radio astronomy organized at Stanford University by Peter Sturrock and Ron Bracewell has gathered a select group of specialists for the last three days." (p.265.)
Jan 1976. "Peter Sturrock, who came over to our house for breakfast, is preparing a UFO questionnaire aimed at scientists. Cufos proposed to publish it. Peter wisely prefers his independence. 'There is a need to separate this research from Cufos, which promotes a belief in UFOs,' he said. He argues that professional scientists are more likely to respond to a questionnaire from Stanford." (p.324.)
Apr 1976. "Peter Sturrock, who is quietly setting up a real scientific group as a committee of the AIAA, sought my advice about the agenda. I said I would stress physical effect cases and avoid pointless quarrels with Menzel and Klass. " (p.332.)
Although the last three posts may seem old history to some, I find they help me understand where Peter Sturrock was coming from.
