This stuff always gets me.
Professional shaman/conspiracists such as Graham Hancock exclaiming that it's 'arrogant' for humans to think that we're the only life in the Universe, and that, by extension, it's arrogant to not believe that Earth has been visited by sentient, superior beings from other worlds.
No, the argument goes something like this:
The odds are very good that there are other sentient beings, perhaps far in advance of humans in terms of technical and spiritual development. However, the distances (and the time it would take to cross them, even at the speed of light) involved are so incomprehensibly enormous (given the relative shortness of individual human lifespans) that it's effectively impossible that anybody has been able to do it.
Maybe, just maybe, airborne anomolies might be one-off top military aircraft capable of a performance envelope not generally accepted as being possible.
Maybe some of these craft are made of exotic materials and processes that are also done on a one-at-a-time basis.
Maybe some of these craft are automonous, and are capable of extreme manueverability that would crush a human pilot with tsunmi-like G-Forces.
Maybe some of these craft are 17 plus billion dollars apiece, a price the media would use to flame citizen outrage.
Of course, it might be a little more comfortable to say that we've been, uh, 'visited' by aliens, intelligent beings from Tau Ceti, who have mastered the science of faster-than-light technology with the specific purpose of dissecting Earth cattle, making funny pictures or obscene graffiti in Earth wheat fields and performing ad hoc anal/rectal exams on some of the locals.
Aaarrrgggghhhh.... quit thinking linearly....
This is what a wormhole is ... I KNOW you've heard it mentioned countless times on Star Trek, and you have had to have heard of 'Hyperspace'. You 'simply' fold normal space, create the wormhole, hop a relatively SHORT distance to your destination, and then allow the wormhole to collapse (ie normal space to 'spring' back). Now, as for the near infinite amount of energy required to do this .... that's a totally different subject.

My Pop saw something weird over his airbase that was flying then took an immediate 90 degree turn and moved faster than any missile he had ever seen. A true UFO--he had no clue what it was, he doesn't think it was alien, but it was unidentified and definitely flying. That's about all he had to say about it.
I could see test machines in the 1990s doing this or maybe even earlier. But in 1962? We must have had one heck of a research division.
