Did you know that an airplane can fly faster than a speeding bullet? The Lockheed SR-71 Blackbird, a US Air Force reconnaissance aircraft, reached speeds of Mach 3.3, or over 3,500 kilometers per hour. It became legendary for flying so high and fast that it was undetectable.
The Soviet MiG-25 Foxbat interceptor was not far behind, reaching Mach 3. Developed in the 1960s, it had a top speed of 3,000 km/h to counter the threat of American bombers, becoming one of the symbols of the Cold War.
Modern fighter jets, like the American F-15 Eagle, can reach speeds of up to Mach 2.5. Its 2,655 km/h (1,655 mph) allowed it to dominate the skies, achieving over 100 aerial victories without a single combat loss for decades.
But the absolute record belongs to NASA's X-15 rocket plane, which reached 7,274 km/h—that's Mach 6.7! Piloted by Joe Walker in 1967, it demonstrated the speed limit for manned flight at the time, reaching an altitude of 108 kilometers.
These machines are engineering masterpieces that broke the sound barrier with astonishing ease. From the SR-71 to the X-15, they forever changed the concept of speed. What supersonic technologies await us in the future? Subscribe to find out!
