From Mach 2.5 to Mach 9.6 — The Fastest Aircraft Ever Built

From Cold War spy planes to NASA's hypersonic rockets, these are the 10 fastest aircraft ever built — ranked by the maximum speed they actually reached. We count down from Mach 2.5 interceptors all the way to a scramjet that hit nearly 10 times the speed of sound. Some were experimental rockets with wings, some outran every missile ever fired at them, and one still holds a speed record that has stood for over 50 years. #FastestAircraft #SR71 #X15 #AviationHistory #Aircraft
