Maj. Grant Pennington, Marine Corps Air Station Yuma, Ariz., Marine Aviation Training Systems Site officer in charge, performs tests run of the new AV-8B Harrier simulator May 19, 2009. The simulator, which can run both day and night missions, is scheduled to be available to pilots Aug. 31, 2009. MATSS plans to receive two F-35 Joint Strike Fighter simulators and possibly one unmanned aerial vehicles simulator within a year or two, and have them linked on a local network with its two Harrier simulators. MATSS also plans for the simulators to eventually be linked to a joint, nationwide network by 2012, allowing pilots here to fly simulated scenarios with other services and their respective aircraft.(Photo by Lance Cpl.
