Base and company officials say the F-21 Kfir aircraft crashed just after 9:15 a.m. Tuesday inside the west gate of the military airfield, about 60 miles east of Reno.
Petty Officer 1st Class Doug Harvey says it was snowy and foggy at the time.
Airborne Tactical Advantage Co. official Matt Bannon in Newport News, Va., says it's too early to say what caused the crash of the single-seat, single-engine aircraft. Bannon says the name of the pilot won't be made public until his family is notified.
The aircraft is one of several types that the company provides under contract to the U.S. military.
