SR-71 picture gallery
SR-71 Blackbird, a high performance airplane which is the
fastest ever. 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. This operating environment makes the aircraft excellent
platforms to carry out research and experiments in a variety of areas -- aerodynamics, propulsion,
structures, thermal protection materials, high-speed and high-temperature instrumentation,
atmospheric studies, and sonic boom characterization.
