Today in History, December 22, 1964:
The SR-71 “Blackbird” reconnaissance aircraft has it’s first test flight from Air Force Plant 42 in Palmdale, California.
The remarkable first “stealth” aircraft’s defense against missiles fired at it…was to simply outrun the assault from it’s ceiling of 70,000 feet at Mach 3…2,200 miles per hour. The skin of the aircraft was designed to expand with the heat of the speed.
