You are so right. The program DID get a) liquid hydrogen-—we made it, pumped it, stored it, and got it to be an effective fuel; b) VERY advanced materials, including some that are still classified; and c) computational fluid dynamics-—which can take SOME of the place of testing. But the biggie was the scramjet-—the rest of it was meaningless if we couldn’t get the scrammie to work.
I follow it a little. First, the USAF has two programs related to the scramjet and fuels that have been successful. They got a scrammie to work up to Mach 10. We could have begun testing the NASP with a Mach 10 scramjet. Second, the developments in the private sector will easily overtake government work in the next 10 years and probably do what NASP was supposed to do anyway.
Sorry. You’ll have to pay through the nose like everyone else.
Go to the link and you’ll know as much about it as I do. As I said, I get nothing from this.
I figured that unless my local library carries it.
Do we have an orbital plane currently?
Consider that the SR-71 Blackbird created almost 50 years ago was capable of mach 3+. It would stand to reason that newer technologies have been developed in the last 50 years that could easily have pushed the envelop for jet powered aircraft to mach 6 and beyond.
No. The last one was the Space Shuttle, which was problematic as you know.
Do you know if they published it in e-book format?
Thanks, Doc!
Sorry, I don’t know much at all. Just found out about it and don’t even know who to contact.
No problem. Thanks again!

Oooh, Larry, I’m headed off to the bookstore, or if need be, the online bookstore!
Truly amazing pics and story. They had to do some amazing things to get those things through, shaving down banks on either side of the road.

That was a great read on the A-12. That was way before the age of computer aided drafting, the draftsmen in those days were GODS. Companies today think some rookie engineer out of college can do drafting, design, and engineering analysis all by his lonesome. You don’t know how such a “fail” concept this is.
Thank you! Modern World is simply a great book. Next to PHUSA the best I’ve ever written. My favorite parts are on the car culture in America and the copycat Russians.
SAo, the B-52 gravity-dropped drones and X-15’s, which then rocket-boosted upwards in “space” - although few (if any ??) had a large enough booster to do more than coast up, get data, then drop back.
The SR-71 launched drones into Chinese airport at mach + speeds. Those were horizontal flight only.
The B-58 Hustler could drop loads at Mach + speeds, so we know the physics and aerodynamics of Mach+ separation pretty well, even back in the mid and late 60’s. Didn’t always work though - the SR-71 drones did have at least 2 failures that I know of.
Could the Valkyrie bomber - which could carry loads internally as large and as heavy as the B-52 could but do it supersonically and to much higher altitudes - carry a meaningful boosted-rocket payload into space? Seems that getting a payload to 75,000 feet and Mach 1. to 2.0 - even if the flight itself were short-ranged - would be a substantial improvement at the cost of refurbing the plane now museumed into oblivion.

No.
Online. No bookstore would carry this one.
You’re everywhere dude! Excellent.
