I'm not saying these guys are genuine, they may be liars, who knows, But I can refute points from both your scenarios:
#1 that captain, who is retired now, gets pulled back into active duty and is court martialed and goes to prison for the divulging of national secrets in a public forum. all of the film and any records of the event are seized and those who put him up to this devulgance are charged as co-conspirators soon to be doing 5 years in prison themselves.
Why would the military brass bother pulling him back for a court martial? This would only lend credence to his story, when, if they just ignore it completely they know that 80% of the public will simply think he is a crazy nutjob and the story dies out quickly. Imagine if the military does pull him in for a court martial, then the media is all over the UFO story because it suddenly has new found credibility.
#2 UFO hounds find some former officer or soldier who was stationed in a possibly interesting place, such as a nuclear weapons facility, and they make a monetary offer to this person to corroborate some story that someone else allegedly told to the UFO hounds.
Cause I'm sure that all these wacko UFO hounds are rolling in the $$$$ and have hundreds of thousands to throw around bribing USAF personnel.
now this former officer or soldier has no idea about any of the alledged events and has never been ordered to keep his/her mouth shut on the matter nor have they been required to sign a secrecy agreement on the matter. they do some general checking on the possible secrecy status of the story to be sure they are not breaking any laws first, when they realize its all just BS and they wont get into trouble they take the free money and spit out whatever story they were asked to corroborate because they are not looking at prison time.
But why? Why would these UFO conspirators do this. They're not coming forward themselves, they get no notoriety. What is there motive for supposedly bribing folks to corroborate fake stories? Money? nope, you say they are losing money. Power? nope, they get no position or esteem from it. Ego? nope, the folks they bribe get all the attention. Your logic is missing a key element.... motive.
Lastly, I said before I met a man who was a lowly MP at Minot, ND in the 80's during a UFO incursion. He told me about it around the campfire one night. I trust him because I have no reason not to. He is not selling his story, he's never been on late night AM radio, he gets no notoriety from it, he is not a wacko or mentally ill, (he is a civilian DOD contractor now.) After the incident he said there was no threatening to keep quiet, or men in black, or secrecy acts to sign. It happened, it was weird, they talked about during their long boring shifts for a while, eventually there was nothing more to talk about, end of story.
Anyways, I respect your, and your father's opinions, and I feel they have some validity, like I said most of it is probably is BS phony stuff.
But I don't think it all is. Look at the JAL 1628 incident, did someone bribe all those pilots, and radar operators too? The FAA obviously thought it had some credence. Or the police officers, they had to have been all bribed beforehand to set it all up, since their radio calls as they chased it are all on tape. What about former AZ governor Fife Symington, he already has lots and lots of money, they must have given him a really humongous bribe. And what about what I personally saw? No one bribed me, and I have been mocked for it, oh well, I'm over it.
In this instance I will concede that it is entirely possible that these guys made it all up for the attention or whatever reason. But still you just can't dismiss all UFO phenomena as liars or wackos.
