This is an interesting take on the subject from Barry Goldwater, who during his 30 years in the Senate chaired both the Armed Services Committee and the Intelligence Committee:
I think Goldwater's avoidance of the words "Roswell" and "crash" was intentional.
That clip reminds me of a joke told by John McCain that has stuck with me for many years. For those of you who don't know this about him, he was smartass and renowned joke teller. Not all his jokes went over well, but he didn't get too flustered about that. One of his staffers told me about a visit to a retirement home near Mesa called Leisure World when he made a joke about it being Seizure World that didn't go over too well with the elderly residents.
Anyway, in 2000 I was at a small event where he was speaking during his first campaign for president and he made a joke about the Democratic frontrunner (and eventual nominee) Al Gore. He had been speaking for a while already and was in full bombastic McCain mode. He started the joke by saying "You've heard about Roswell, right?" That's a paraphrase, but it's not off by more than a word or two. But then, his tone shifted down, his voice became much softer, he lowered his eyes and looked down, and said again "Everyone knows about Roswell, right?" He may have used the words "crash" and something like "alien" or "flying saucer" in conjunction with the word "Roswell," but I don't remember specifically. I'm very familiar with the story so that part didn't stick with me. Then he looked back up at the crowd gathered around him (and I do mean
around; this was in the backyard of a private house in the Virginia suburbs of DC and there was no stage or arranged focal point for a speaker, people just surrounded him on all sides while he spoke), raised his voice to the previous volume and said you can check for yourself, but "Al Gore was born nine months to the day after the Roswell crash!"
I have checked, and Gore was actually born 8 months and 24 days later, but who's counting?
Why this joke has stuck with me for more than 20 years is the way he lowered his eyes and his voice when he repeated the "everyone knows" part. The only way I can explain it is that it seemed obvious to me that he was reassuring himself that he wasn't improperly divulging classified information, that the story was so well known that he wasn't saying anything not already in the public domain.
Just one small data point in a very large subject, but I found it compelling and still do so I thought I'd share.
