While the X-15 was an amazing aircraft, it was a totally different technology. When scramjets are perfected, it will be as much of a jump in aviation tech as going from props to jets.

You got that right, the X-15 was a rocket with a range of less than 300 miles. The Scramjet is a air breathing engine. You want to talk top of the mark, there is the SR-71, 2900 miles at Mach 3.3+, it has out run rockets fired at it. The Scramjet is leaps beyond that even, in air breathing engines...........

The Blackbird did 31+ once that is known about. Now that is an amazing aircraft. It is retired but still holds every record out there. Wonder what they have now--must really be something.

You can bet they didn't retire the SR-71 unless they had something better already deployed.

If they're willing to talk about the wave rider, it's very near deployment, (Or already in limited deployment) and it's replacement is on the drawing boards.

You left out the part where it ran into its own cannon shells. Apparently if you're gonna fire cannon shells from a perfectly good airplane it's a good idea to make sure that the BB's are flying substantially faster than the aircraft they're shot out of. Apparently those slide rules don't help when you misplace a zero somewhere.

It's pretty funny that they were worried about it being shot down with a missile. It would've taken the Russians longer to track and acquire a lock on it than it would've been inside the engagement envelope of anything they had to launch at it.

I also like the fact that it was made with Russian Titanium. Nothing like building weapons with the material that the enemy makes for you.

They retired the SR-71 because Keyhole was providing better imagery once the camera (lens technology, actually) was of sufficient quality to negate the utility of the airplane.

That said, it was a damn impressive feat of engineering and science.

The one that has me wondering is the X-37, I really wonder what it was doing the 6 months or so it was up in space on the 2 missions it has flown.

It's flown three missions, so far as I know.

My guess is simple spying, which is what the Air Force, CIA, and NSA are traditionally most interested in.

Possible it was keeping a close eye on Iran or something, seems it would be easier to move it into place than moving one of the spy satellites

That could be. Short term orbits compared to the satellites means it could burn more fuel moving around.
