The MC-12 is a Hawker Beechcraft 350 with a camera that can supply video to troops on the ground and sensors that can intercept enemy communication. The crew consists of two pilots, an airman who operates the sensors and a cryptologist who analyzes the intelligence the plane scoops up.
MC-12 crews have flown more than 2,000 missions in Iraq, Air Force records show. The first aircraft arrived in Afghanistan last December.
