What evidence, besides shaky eyewitness accounts, is there these craft ever reached such high speeds? People are very poor observers.
Why do you consider it shaky eyewitness testimony? Could you please divulge exactly what it was about the witnesses which causes you to believe their accounts were not accurate? Or are you using a generalization - since it's a UFO, it automatically becomes shaky evidence?
Especially considering several of the witnesses were police officers. Trained observers, moreso than your average witness.
I think witnesses could tell the difference between 53 mph (top speed of known blimps) or we'll say heck, 80mph.. because it was a super-secret stealth blimp with super technology behind it! One of the police officers who saw this flying by the road, called in because he thought a plane was about to crash or was in trouble. Others reported it moving much, MUCH quicker than your average blimp.. stealth or otherwise.
The size, silence and speed of these objects imo, is what pretty much nullifies the theory it was any governments secret tech. Black projects typically are not flown over public land as well, for obvious reasons. There is a reason they have huge amounts of uninhabited land to test these sorts of things. Maybe a pilot took it for a joy ride? Huge, silent craft moving at those speeds... we don't even begin to have the science behind the tech that would be necessary to make it a reality.


i believe these guys i think what they saw was real wheather it was ufo or super secret airforce test flight of some radar deflecting plane its
legit
