In late October, two research helicopters from the manufacturer Sikorsky, a Lockheed Martin company, made a dozen test flights over Long Island Sound, Connecticut taking care to avoid other aircraft in the area around them. Except the ordinary-looking helicopters were flying autonomously—guided by NASA-designed software—and those other aircraft were virtual, part of a simulation to test pilotless flight systems. This was the first time two autonomous aircraft were flying at one another using NASA designed collision avoidance software.
