The U.S. Army has flight-tested the Sikorsky Autonomy Research Aircraft (SARA), a Sikorsky S-76B modified as an optionally piloted vehicle (OPV) demonstrator. This marked the first time that non-Sikorsky pilots had operated the SARA as an OPV aircraft. For the Army’s mission software flight demonstration, the SARA aircraft was controlled from the ground and was also "flown" by onboard pilots using a tablet and mouse-like inceptor. The flights were undertaken as part of a collaboration between the U.S. Army’s Aviation Development Directorate, Sikorsky, and DARPA (the U.S. Defense Advanced Research Projects Agency).
