Well, Fouché is an author of a (rather poorly written, IMO) science fiction book, and did not, AFAIK, work at Groom. Part of the stuff that you see indicates that the person who wrote it has an active imagination but not much technical knowledge.

For example, he claims that the SR-75 flies at an altitude of 13,000 meters, which is only 42, 650 feet. The U-2, using 1950’s technology, flew much higher than that, and the SR-71 flew even higher. An aircraft flying at the altitude claimed by Fouché , even at its purported speed, would be an easy target for modern SAMs.

Another error is that the so-called Scramp “…is used to place small satellites in orbit and can “…attain speeds of Mach 15, or just under 10,000 kmph ….” 10,000 km/hr is equivalent to 2778 m/sec or 6,214 mi/hr, and yet orbital velocity is about 7800 m/sec or about 17,500 mi/hr. In other words, the Scramp simply can’t go fast enough to do what Fouché claims it can.

Fouché is able to get away with his stuff because most of his readers don’t know much basic physics, but sooner or later, someone with a technical education reads his stuff and debunks it.
