A fully fueled SR-71 takes off from Air Force Plant 42, Palmdale, CA with a T-38 chase plane. SR-71 pilot: B C Thomas, RSO: J T Vida; T-38 crew: Tom Tilden, Phil Soucy, October 1987, photographed by Mike Relja.

I kept the airplane close to the runway to attain airborne single-engine minimum control speed as rapidly as possible. Single-engine control speed for a fully fueled SR-71 was around 260 knots, whereas the liftoff speed was 210 knots and maximum tire speed was 239 knots. The safest takeoff technique was to establish a level acceleration (speed increase) after main-wheel liftoff to exceed the single-engine minimum control speed quickly. After the minimum control speed was attained, then it was safe to pull up and accelerate away from the ground, finally reaching the climb speed of 450 knots (520 mph) shortly after the pull-up at time 0:21. The SR-71's airspeed at pull-up was 460 mph (400 knots). Everything happened very quickly as the video is only 1 minute, 4 seconds long, from lift-off to climb speed at an altitude of about 8,000 feet.

The SR-71 aircraft is #972 which now resides in The Smithsonian Air and Space Museum at the Steven F. Udvar-Hazy Center near Washington Dulles International Airport.
