The early 1960's saw embedded computers advance sufficiently to be used in Apollo spacecraft. By the late 1960s, NASA Flight Research Center (now Dryden) engineers began work to replace mechanical flight-control with digital fly-by-wire technology. Support came from Neil Armstrong who backed the transfer of a U.S. Navy F-8C Crusader to NASA which became the F-8 Digital Fly-By-Wire (DFBW) research aircraft. Proven performance and solid cooperation between NASA and industry translated into use of DFBW systems in new aircraft design in a remarkably short time.
