Lockheed SR-71A Throughout its nearly 24-year career, the SR-71 remained the world's fastest and highest-flying operational aircraft. From 80,000 feet, it could survey 100,000 square miles of Earth's surface per hour. On July 28, 1976, an SR-71 set two world records for its class -- an absolute speed record of 2,193.167 mph and an absolute altitude record of 85,068.997 feet. #avgeek #history #sr71blackbird | National Museum of the U.S. Air Force
