That name Dave McCollum is spookily similar to Dave McGollum (sp?), who was copilot of the flight test Canadair that was lost over Edwards in about 1980. The FTE bailed ok; Dave bailed almost too late, and was in hospital six months recovering from broken legs, etc. The Capt didn't get out. I met Dave in about 1983, when he was FAA pilot DER.
