The Lockheed SR-71 Blackbird had some mind-blowing technical specs! β
οΈ It was 107 feet long, with a wingspan of 55 feet. It weighed about 140,000 pounds! It was powered by two Pratt & Whitney J58 engines, which allowed it to fly at speeds over 2,200 miles per hour! That's faster than a cheetah, the fastest land animal! The Blackbird could fly at altitudes of 85,000 feet, where commercial airplanes usually fly around 30,000 feet. Its advanced design helped it to stay stable and controlled at high speeds. π
