I knew Klass when I was stationed in DC in the 1960s. I would go to the monthly luncheons of the American Institute of Aeronautics & Astronautics. There was always some big name speaker from the government or industry. Klass always sat at a table just under the head table, and unlimbered his tape recorder during the speech. He insisted on complete silence at the table, so as not to get extraneous noise on his recording. I recall being shushed by him once.
The link mentioned McDonald, who was a professor of meteorology at some university in Arizona. He had taken a sabbatical, and investigated UFOs. He had become convinced we were getting visitors from other planets. He gave a briefing on his conclusions at the Pentagon. I wangled myself an invitation. As a Major I was sitting in the back row. The 4-stars were all in front. After McDonald gave his briefing, one of the 4-stars asked him, if we're being visited by vehicles from outside, how come they never crash? How come there's never any wreckage? McDonald stood there with the blandest smile I've ever seen on a human face, and said, "Maybe their Zero Defects Program really works." That brought the briefing to an end.
As an aside, the AIAA luncheons would always be attended by at least one person from the Soviet Embassy. I had interesting conversations with several of them. I'm sure they thought I was spying on them, since I was in uniform. It would be interesting to see what reports they submitted on me.
"Maybe their Zero Defects Program really works."LOL! Thanks JoeFromSidney.
