Boeing has managed to transform several Lockheed Martin F-16 fighter jets into pilotless drones. During the unmanned test flight, one of the jets cruised at 40,000 ft and hit speeds of Mach 1.47 while performing a series of maneuvers, including barrel rolls and a “split S”.
The F16 took off from a base in Florida and flew to the Gulf of Mexico while being trailed at all times by two chase planes monitoring its course. According to the project’s chief engineer, Paul Cejas: “It flew great, everything worked great, [it] made a beautiful landing – probably one of the best landings I’ve ever seen.”
