The Lockheed SR-71 Blackbird was a remarkable aircraft that could fly at speeds over Mach 3.2 and at altitudes up to 85,000 feet. It was the fastest manned aircraft ever flown and still holds many speed, altitude, and distance records for a manned aircraft.
Flying in such an extreme environment required special training and equipment for the pilots. The pilots of the SR-71 wore full-pressure suits that resembled those worn by astronauts. The suits protected them from low pressure, low temperature, and lack of oxygen at high altitudes. They also provided protection in case of an emergency ejection.
The pilots also had to cope with the high g-forces and acceleration that resulted from flying at such high speeds. The SR-71 could accelerate from Mach 1 to Mach 3 in less than 15 minutes, which put a lot of stress on the human body. The pilots had to undergo rigorous physical training and medical examinations to ensure they were fit for the mission. They also had to use special techniques to breathe and move their limbs during high-g maneuvers.
The pilots also experienced a unique sensation of speed when flying the SR-71. They could see the curvature of the Earth and the stars in broad daylight. They could also see the shock waves forming around the aircraft as it broke the sound barrier. The SR-71 flew so fast that it could outrun any missile or enemy aircraft that tried to intercept it. The pilots had to rely on their instruments and their instincts to navigate and control the aircraft.
