Tank Smashing. Only a few hours before, desperate battles had been fought at the Maria Theresia barracks, at the Communist Party headquarters, and at the steel mills at Csepel island. With their heavy 76-mm. guns, the Soviet tanks had attempted to blast the rebels out of their hiding places, but the "incredible youngsters" had evolved their own technique for dealing with the mighty 26-ton tanks. First they would fire on the tanks from upper-story windows, then as the big T-345 rumbled up, their great guns elevated, a small boy would leap out of a doorway, fling...
Supersonic speed has brought a new hazard for jet-plane pilots: shooting themselves down with their own gunfire. Last week the Navy told how Test Pilot Tom Attridge was trying out the 20-mm. guns of a Grumman F11F-i fighter off Long Island. He put the airplane into a dive, speeded up to 880 m.p.h. and fired a four-second burst (about 70 rounds). Then he went into a steeper dive and fired another burst. As the last bullets left his guns, something struck and shattered his windshield. Pilot Attridge thought he had run down a bird. He headed...
Examination of the airplane proved that Pilot Attridge had hit no bird; he had overtaken and run down the fire from his own guns. A nonexplosive 20-mm. bullet (used in practice) had gone through his windshield. Another had hit the engine, a third had punctured the nose. If the projectiles had been explosive, Pilot Attridge would not have got home alive...
...Producer Todd took his picture on the world's largest film-exactly twice as wide (70 mm.) as the normal Hollywood stock-and has projected it on one of the world's largest indoor screens-a vast concave gullet that opens almost as wide as Cinerama, and possesses much of the same power to suck the spectator out of his seat. Not content with that, Todd flooded this huge surface with a light almost twice as intense as any ever seen onscreen before, and so hot that the film has to be refrigerated as it passes through...
Calm and brainy, Bell lost no time striking out into the fields he liked best-research and development. His first fighter plane in 1937 was a flying machine-gun nest ; it had twin engines, a 300-m.p.h. top speed, bristled with two 37-mm. cannon, four .50-cal. machine guns. No sooner was it aloft than Bell was busy with a radical single-engined fighter, the P-39. It was the first single-engined U.S. fighter with tricycle landing gear, had a 37-mm. cannon firing through the hollow prop hub. Expanding from 100 workers to 55,000 at five...
