...operate, it must first be accelerated to a speed of several hundred miles per hour by an auxiliary turbojet or rocket engine, or get a lift from a conventional plane. After that, enough air is rammed into the engine's front inlet to set up a pressure barrier that forces the burning gases to escape at the rear, thus providing thrust (see diagram...
After delivering supplies to a space station, say, the scramjet would fire retrorockets, re-enter the atmosphere and fly back to earth. It would be capable of landing at any large airport with the aid of a turbojet engine, which would begin operating at lower speeds after the scramjet engine is shut down and bypassed. A 500,000-lb. scramjet might well be able to carry as much payload into orbit as a 4,000,000-lb. multistage rocket...
...ducted 7-ft. fans that the X-22A uses as props are a futuristic blend of modern metallurgy and plastic engineering-fiber-glass blades with steel cores and nickel edges. The power behind those fans is a Rube Goldberg blend of engineering-four turbojet engines feeding a total of ten different gearboxes. The barrel-like ducts, along with their -big props, can be rotated by separate hydraulic motors. With the ducts horizontal and the props pointing forward, the X-22A should be capable of more than 300 m.p.h. in level flight; with ducts rotated to a vertical position, the ship...

When Soviet Premier Nikita Khrushchev slowly emerged from his TU-104 turbojet in Bulgaria last week, he seemed to lack his usual bounce. He had lost weight, the skin on his neck and face was slack, his eyes lacked sparkle. It took him a full day to recover anything like his old roadshow form. Then, in the Black Sea city of Varna (formerly called Stalin), he planted two small trees, after which he handed the shovel to startled Foreign Minister Andrei Gromyko. "I have helped build Communism," joked Nikita. "Now you've got to work. This...
