Why were people made to "Disappear" who had real UFO experiences in the 1940s, 1950s and 1960s and sometimes after that too?

The main reason was that Eisenhower as president purchased flying saucers so that he could "Repair time" when someone nuked a city a country or this world out of existence. And there was a need to keep this sort of thing secret because Time Travel is thousands of times more dangerous than nuclear weapons for a variety of reasons.

So, it was thought that eliminating ANYONE who was visiting with aliens (and who wouldn't shut up about it) would allow this time travel equipment bought by President Eisenhower to be safe here on earth as long as the general public wasn't sure that it existed. And the easiest way to make sure that people wouldn't be sure that it existed was to eliminate anyone who had any real evidence that all this was actually true.
