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 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.
