The thing about the SR-71 is that the top speed of Mach 3.2+ really is pretty bloody vague. I've read multiple accounts from pilots having their top speed runs "called" when the thing was still accelerating like crazy. There is so much we will never know about that plane IMHO. The U-2 being shot down was what really poured the fuel on the final development stages of the SR-71, which had been in the works since 1958. Originally designed as a fighter (hence the YF-12), its final incarnation was simply a spy plane.
God only knows what the true top speed was of a plane that flew at the edge of space; 80K to 100K ft. To experience that? I am sure there is absolutely nothing else like it.
No, Lockheed didn't have a monopoly on innovation, but their Skunkworks were probably the best of the breed. Working with Pratt & Whitney, the unique hybrid turbo/ramjet propulsion, making the impossible possible? The SR-71 is the product of that. It truly is, IMHO, the best of American innovation; The hallmark of what can be done when the brass tacks are down and you sink or swim. And this is coming from a (Canadian) guy that knows all about the Avro fiasco.
The XB-70 came after the SR-71, and didn't incorporate the same sort of hybrid engine technology (they used GE turbines) which, IMHO, was a poor move. The SR-71's propulsion was superior, hence its significant tenure, and the XB-70 project could have benefited from the hybrid propulsion technology.
