Developed for the USAF as reconnaissance aircraft more than 40 years ago, SR-71s are still the world's fastest and highest-flying production aircraft. The aircraft can fly more than 2200 mph (Mach 3+ or more than three times the speed of sound) and at altitudes of over 85,000 feet. As research platforms, the aircraft can cruise at Mach 3 for more than one hour.
