TACE lays down foundation for future UAV test safety
Engineers prepare an unmanned jet-powered aircraft for a flight test
at Edwards Air Force Base, Calif., July 25. The flight tested a software
suite called TACE, Testing Autonomy in a Complex Environment,
developed by John Hopkins Applied Physics Lab.
