The Lockheed YF-12 is an American Mach 3+ capable, high-altitude interceptor prototype, developed and manufactured by American aerospace company Lockheed Corporation.. The interceptor was developed during the late 1950s and early 1960s as a potential replacement for the F-106 Delta Dart interceptor for the United States Air Force (USAF).
The Pratt & Whitney J58 (company designation JT11D-20) is an American jet engine that powered the Lockheed A-12, and subsequently the YF-12 and the SR-71 aircraft. It was an afterburning turbojet engine with a unique compressor bleed to the afterburner that gave increased thrust at high speeds.
The YF-12 program was a limited production variant of the A-12. Lockheed convinced the U.S. Air Force that an aircraft based on the A-12 would provide a less costly alternative to the recently canceled North American Aviation XF-108, since much of the design and development work on the YF-12 had already been done and paid for. Thus, in 1960 the ...
August 12 - Air Inter Flight 2611, a Vickers Viscount, crashes into a farmhouse near Lyon in poor weather conditions, killing 16 including one on the ground. August 21 – Aeroflot Flight 366 , a Tupolev Tu-124, ditches in the Neva River in Leningrad after engine failure; there are no fatalities among the 52 on board, but the aircraft is destroyed.
This is a list of aircraft produced or proposed by the Lockheed Aircraft Corporation from its founding as the Lockheed Aircraft Company in 1926 to its merging with Martin Marietta to form the Lockheed Martin Corporation in 1995. Ordered by model number, Lockheed gave most of its aircraft astronomical names, from the first Vega to the C-5 Galaxy.
Both aircraft then made near zero-visibility approaches relying nearly exclusively on the flight engineers and aerial gunners inputs for precision navigation. Following the successful survivor contacts and recovery by the Flight's Pararescuemen, Jolly 11 and Jolly 12 were individually engaged by separate multiple surface-to-air missiles attacks ...
The "Electra Junior" name did not catch on in the way that the original Electra's name had. Most users simply referred to the aircraft by its model number, as the Lockheed 12. [3] The original Lockheed 12 version, with Wasp Junior engines, was the Model 12A. [4] Almost every Lockheed 12 built was a 12A or derived from the 12A.
About 1 p.m. Mountain Time in Campbell County, Wyoming, a Pilatus PC-12/47E single-engine aircraft crashed north of Gillette, about 223 miles north of Cheyenne, the capital of Wyoming. The crash started a wildfire which firefighters contained to an area smaller than one square mile.
