But would you admit that given the nature of what we know of past military projects like the Spirit, Nighthawk, the SR-71, the U2, the Aurora project, and the scramjet, that it is a scenario that is 1000% more likely than anything extraterrestrial or supernatural?
With the absence of any other credible explanation, I think it is safe to say that what these people are seeing are a varying mix of optical illusions, natural phenomena, misidentified landmarks, and top secret military projects.
Do these aircraft not appears as typical aircraft more or less?
You seem to be suggesting that witnesses, such as professional pilots, design engineers, cops, and military personnel are not capable of distinguishing between a modern, man made aircraft, and an unidentified object...
Is this what you're suggesting?
