Mission: Blackhawk is an add-on for Microsoft Flight Simulator X from the flight sim specialists at Abacus Software, Inc. The game puts players at the helm of Blackhawk helicopters, the utilitarian choppers from Sikorsky that are used by the U.S. military and governments around the world. Desktop pilots can fly simulated versions of the UH-60L Blackhawk, SH-60 Seahawk, HH-60G Pavehawk, and the HH-60J Jayhawk. Each aircraft is available for use in the Flight Simulator X world and for helicopter-specific missions like anti-terrorist training, natural disaster rescue, and special ops team insertion training. Mission: Blackhawk requires previous installation of Flight Simulator X or Flight Simulator 2004.
