The author talks about the air force making a aircraft secretly known as flying saucer.

The disc shaped craft-- which comes complete with an ejector seat and was powered by a "ram jet"-- was designed to reach a top speed of Mach 4 and reach a ceiling of 100,000 ft, according to a lengthy document, titled "Project 1794, Final Department Summary Report," and dated 1956.

"Six Armstrong Siddeley Viper turbo jets-- 1900 lb. thrust, 22.0" overall diameter, 525 lb. weight each-- mounted ridally in the wing, exhasting inwards; uses gas generators to drive a pair of contra-rotating centrifigual impellers.

"The efficiency of the airframe at supersonic speed appears, good and the engine reasonable, so that a long supersonic cruise range is also forcast."

I've heard of flying saucer's from outer space, but never would have thought americans would build an aircraft thought to be from out of this world.

If we can ever get a ship built like that we can be able to go out to space without space suits or rockets, just this flying saucer aircraft.
