I give you an exact quote that says it looked like a large flying wing and a film of a flying wing from that time period and you call it "irrelevant"? Why? What logical reason can you give that makes you so sure?
Just because Kelly Johnson said it "looked like" a flying wing, that doesn't mean that it
was one. Remember that his eyesight was not perfect.
Showing us a film of a flying wing doesn't prove anything.
Here's a video of a couple cute little bonobo chimps hugging each other. Does that prove it was a bonobo chimp?
Astrophotographer has given the excellent, logical reason that it's humanly impossible to visually discern an aircraft of 200' wingspan from the alleged distance.
Stray Cat has not only
given, but also
demonstrated that the eyewitness accounts cannot possibly have been accurate, due to major inconsistencies among them.
Stray Cat has also rightly pointed out that no object could possibly have been visible to both parties simultaneously and be observed by both parties moving in the way both parties described at the distance they reported.
He pointed out that for any object to
appear to be moving in a general direction away from both parties simultaneously, the rule of parallax indicates it would have had to be far more distant than their own estimates, on the order of 10x or more. That of course would have rendered their own size estimates off by orders of magnitude, far, far larger than the reported 200' wide.
Yet you ignore all that objective, mathematical evidence in favor of cherry-picking bits and pieces of the eyewitness accounts that support your preferred conclusion.
Those are the logical reasons and objective evidence that indicate that it was probably a very distant, strangely-shaped cloud many hundreds of yards (or even a mile or more) across, and not an extremely rare experimental aircraft all but one of which crashed, and which had been canceled from production and testing years prior to this sighting.
