The current world-record for highest cannon projectile flight is held by Project HARP’s 410 mm (16 in) space gun prototype, which fired a 180 kg (400 lb) Martlet 2 projectile to a record height of 180 kilometres (590,000 ft; 110 mi) in Yuma, Arizona, on November 18, 1966.
The previous record was 14,938 meters (49,009 feet). It was set in 1986 by Robert R. Harris, flying from California City and reaching his record height over Mount Whitney, California. [6] This may be near the limit for standing mountain waves in temperate latitudes, although in unusual meteorological conditions much higher altitudes may be ...
6,400 metres (21,000 feet) This height was recorded over Nevada; [1] [4] [5] This record occurred when a Lockheed L-188 Electra turboprop airliner operating a Western Airlines flight suffered a bird strike at cruising altitude. [8] Bar-tailed godwit: Limosa lapponica: Scolopacidae: 6,000 metres (20,000 feet) [5] [9] It can reach this height ...
The SR-71 was the world's fastest and highest-flying air-breathing operational manned aircraft throughout its career and it still holds that record. On 28 July 1976, SR-71 serial number 61-7962, piloted by then Captain Robert Helt, broke the world record: an "absolute altitude record" of 85,069 feet (25,929 m).
It has already surpassed the sub-sonic altitude record set in 1989 by a Lockheed U-2. The program also hopes to beat the 85,069 ft altitude record set in 1975 by a Lockheed SR-71 Blackbird. [3] The aircraft is made from composites. Its 83.83 ft (25.55 m) span wing has a high aspect ratio of 27.1 and is equipped with airbrakes.
The X-15 set speed and altitude records in the 1960s, crossing the edge of outer space and returning with valuable data used in aircraft and spacecraft design. The X-15's highest speed, 4,520 miles per hour (7,274 km/h; 2,021 m/s), [ 1 ] was achieved on 3 October 1967, [ 2 ] when William J. Knight flew at Mach 6.7 at an altitude of 102,100 feet ...
