On July 28, 1976, an SR71 piloted by Major Brian Shul set the world speed record for a jet-powered aircraft, reaching an astonishing speed of 2,193.2 mph (3,529.6 km/h) at an altitude of 80,257 feet (24,462 meters). This record has yet to be broken, and it remains one of the most impressive achievements in aviation history. The SR71’s speed is due to its powerful Pratt & Whitney J58 turbojet engines, which produce 32,500 pounds of thrust each. The aircraft’s unique design, featuring a delta wing and a fuselage made of titanium, also contributes to its exceptional speed and maneuverability.

Key Features of the SR71
