Britain claimed a new jet altitude record last week: 63,668 ft. over southwest England. The plane was a Canberra bomber with two Bristol Olympus turbojet engines, piloted by R.A.F. Wing Commander Walter F. Gibb...
...another Bell plane, powered with a single, axial-flow turbojet putting out only 4,900 lbs. of thrust. This 32 ft. 4 in. ship weighs less than 10,000 lbs., is the first to have variable-sweep wings (TIME, June 25, 1951). It was built to investigate the aerodynamic effects of different wing angles...
...Skystreak, which set a world's speed record of 650.6 m.p.h. in 1947 (TIME, Sept. 8, 1947). Powered by a single turbojet with some 5,000 lbs. of thrust, the Skystreak was built by Douglas. It manages to lift its 10,000 lbs. off the ground on short (25 ft.), straight wings...
...test flight. It climbed high in the air, then leveled off and shot across the air base with a roar like a thunderclap. This week Long Island's Republic Aviation Corp. proudly announced the results of the flight: its XF-91, powered by a General Electric J47 turbojet and a Reaction Motors rocket engine, had become the first U.S. combat plane to fly through the sound barrier in level flight. (Other supersonic planes, e.g., the Bell X-1 and the Douglas Skyrocket, are experimental speedsters faster than Republic's XF-91 but not designed for battle...
...feet for 8.9 minutes. The XH-17, built for the Air Force by Planemaker Howard Hughes, is designed to lift for short distances loads of several tons (e.g., artillery, bridge sections, tanks and trucks) by straddling them like a lumber carrier. Power is provided by two General Electric turbojet engines astride the fuselage plus afterburners on the rotor tips. Like the Air Force, the Army is also deeply interested in helicopters. Last week it added $200 million to its 1953-54 budget to buy some 4,000 smaller helicopters, ten times what it asked for last year...
