Sadly, I have been unable to source the original video. All that I know, it that it has not been 'debunked' as a re-creation.
I'll remind you that it doesn't have to be debunked. What needs doing by those who claim it is genuine is for those people to provide evidence to support such a claim.
As my (and other's) extensive research into it has never managed to find any verification or provenance for this footage, I don't believe this footage is mentioned in Blue Book along with the UFO report and no reference to it is mentioned on any of the FoI releases concerning this incident, we can safely assume it is not actually a piece of evidence but a representation of what some people claim to have seen (even though reading the witness statements in Blue Book I can not find a single one who mentions a formation of UFOs flying over the Capitol Building).
Also, I've not found any photographs on the front page of any papers.
That's OK, it's because there aren't any. At the time, this story was about radar returns and the USAF sending planes out to investigate. It had nothing to do with a formation of flying saucers over Capitol Hill. That footage only appeared much later (though to my knowledge no one has dated it, no reference of it appears contemporary to that time).
That said, the most convincing evidence that these sightings WERE of an advanced technology, are the jet pilot reports and the radar tracking information.
If you read the Blue Book statements from ATC radar operators, they are talking about random AP returns over a period of a few months. Yes there were certain nights where the returns were more frequent but as far as I saw reading the original blue book statements and documentation, non of the returns were ever confirmed with pilot sightings.
Moreover, that the event happened TWICE, and not again since...
It happened (the radar part) over several months.
The "Mass Hysteria" explanation IGNORES the reports from the radar tracking stations and the jet pilots who were unable to catch them.
If the radar tracking stations were seeing AP, of course the pilots wouldn't be able to catch them. If the pilots were looking for something in the air and there was actually nothing there. Of course some pilots could have seen a light in the distance and given chase, but nowhere are any of the radar returns verified with a positive sighting.
This event IS the most credible evidence that 'they' exist, I am prepared to both accept and present as such.
Only if you use Wikipedia and UFO websites as your source of information.
Looking at the original documentation tells a slightly different and less sensational story.
