While some kinds of artificial intelligence (AI) spend time chatting with people online, others are piloting jet fighters. Aerospace company Lockheed Martin recently revealed its VISTA X-62A tactical test aircraft was flown completely autonomously for the first time. The test aircraft, essentially a modified F-16D, was flown for a staggering 17 hours across 12 different flights above Edwards Air Force Base in California. The computer combined two different autonomous systems to pilot the plane: the Model Following Algorithm (MFA) and System for Autonomous Control of the Simulation (SACS). It's not clear exactly what kinds of activities were peformed by the AI, but it's safe to say it was a little bit more than an average flight on autopilot.
