Records
The SR-71 remained the world's fastest and highest-flying operational manned aircraft throughout its career. From an altitude of 80,000 ft (24 km), it could survey 100,000 square miles per hour (72 square kilometers per second) of the Earth's surface. In addition, it was accurate enough to take a picture of a car's license plate from this altitude. On 28 July 1976, an SR-71 broke the world record for its class: an absolute speed record of 2,193.1669 mph (3,529.56 km/h), and a US "absolute altitude record" of 85,068.997 feet (25,929 m). Several planes exceeded this altitude in zoom climbs but not in sustained flight. When the SR-71 was retired in 1990, one was flown from its birthplace at United States Air Force Plant 42 in Palmdale, California to go on exhibit at what is now the Smithsonian Institution's Steven F. Udvar-Hazy Center (an annex of the National Air & Space Museum) in Chantilly, Virginia. The Blackbird, piloted by Colonel Ed Yielding and Lt. Col. J.T. Vida, set a coast-to-coast speed record at an average 2,124 mph (3,418 km/h). The entire trip was reported as 68 minutes and 17 seconds. Three additional records were set within segments of the flight, including a new absolute top speed of 2,242 mph measured between the radar gates set up in St. Louis and Cincinnati. These were accepted by the National Aeronautic Association (NAA), the recognized body for aviation records in the United States.
