Not to butt in. Have been considering the SR-71 and it's technological and engineering achievements at the time it was developed and the fact it still stands as the fastest jet ever developed a clear sign that other technologies that supercede it have must have been developed by now. Been thinking about this for a while now since the soft roll out and existence of UFO has been going on the past few years.
Absolutely. No doubt. The question that I always come back to is why did the buck stop there? Why was the bar never raised? The only answer that seems to make sense is that the tech that came after was to sensitive. Maybe challenged the laws of physics and to reveal it to the public would cause too many questions. UFO at this point has been confirmed by Military and Navy. IMHO they have had the tech for decades.
The mig's were developed for speed and maneuverability. The SR-71 was developed for strait line speed only, as a rapid response nuclear delivery system (as I understand it) It would be like comparing a drift car to a top fuel drag car.
