General Atomics Aeronautical Systems Inc. (GA-ASI), a provider of aerial vehicles and radar solutions, is expanding its Flight Test and Training Center (FTTC) at the Grand Sky Unmanned Aircraft System (UAS) Business Park near Grand Forks, North Dakota. The company says the growth of the facility from 5.5 to 20 acres will help meet its increasing demand from U.S. and international customers for flight crew training and sensor system testing.
