About 10 years ago I wrote a history of the National Aerospace Plane Program, published by the USAF. It was restricted, expensive, and difficult to obtain. I guess the USAF decided to make it more available, releasing it in paperback. I just discovered it, but I've talked about this project with many of you:
Since the definition of hyper is exactly the same as super, could you please tell me the difference between supersonic and hypersonic?
“Since the definition of hyper is exactly the same as super, could you please tell me the difference between supersonic and hypersonic?”
Five or more times the speed of sound.
Book looks like it belongs in my library, next to all the other USAF books an NCO collects over the years.

You’re the author and they didn’t tell you there was going to be a new edition? Do you at least get royalties?
Are we the only two two letter members?
Is there a place where I can get a pirate copy heh heh.
No, no royalties on this because I was hired to produce the work as a program historian. And no, they didn’t tell me about the new edition.
hypersonic is super x about 10, but usually the term means Mach 5 or above.
That’s a shame. Do you keep up with the developments on the subject? Are we any closer today than we were 10 years ago?
Wow~! DOCTOR LS- thats way cool
Distribution and rights? Available on kindle readers, or only through Amazon as paperback?
Transonic Mach 0.8 to Mach 1.23 (at sea level)
Supersonic Mach 1.0 (768 mph) to Mach 4.99 (3,804 mph or 6,123 kph at sea level)
Hypersonic Mach 5.0 (3,805 mph or 6,124 kph, at sea level) or faster
LEO (Low Earth Ordit) speed 17,450 mph

USAF X-51A Waverider
Is that the Aurora or whatever it was called, that story in the late 80s/early 90s? I can recall stuff like ‘it had a contrail like donuts with a string through the holes’ and it made a pulsing ripping noise or something.

The X-51A Waverider is an unmanned scramjet-powered demonstration aircraft, capable of achieving hypersonic speeds five times the speed of sound. At that speed an aircraft could travel across the U.S. in under an hour.
I like to think an Aurora or two is flying around out there somewhere. The NASP was ambitious as a mach 25 vehicle (low earth orbit) and great strides were made to achieve that end. There were six enabling technologies to make that happen and I know at least three had been completed by 1997. I slipped up in a meeting once and called it Hyperspace, boy the laughs I got on that one. Streaking across the sky like a meteor sure seemed like Hyperspace to me. Thay called us Naspeteers, welcome to the club Dr. Schweikart. Thanks for the history and links everyone.
Thank God for gutenberg and the Internet Archive, where more than a lifetime could be spent reading free and excellent books without spending a penny.
