aviationgreats: I fulfilled a childhood dream this past weekend. I stood next to the baddest looking plane ever made. The SR71 Blackbird! The Blackbirds could cruise at Mach 3+. Mach 1 is the speed of sound, on the order of 1,100 feet per second. The muzzle velocity of most rifles is 1,500 to 2,000 feet per second. The Blackbirds routinely flew faster than a rifle bullet! -- source link
