Phantom in the Sky is the story of a Radar Intercept Officer (RIO) in the back seat of the supersonic Phantom jet during the Vietnam War—a unique, tactical perspective of the “guy in back,” or GIB, absent from other published aviation accounts. During the time of Terry L. Thorsen’s service from 1966 to 1970, the RIO played an integral part in enemy aircraft interception and ordnance delivery. In Navy and Marine F-4 Phantom jets, the RIO was a second pair of eyes for the pilot, in charge of communications and navigation, and great to have during emergencies. Thorsen endured the tough Platoon Leaders Course at Quantico and barely earned a commission.

He participated in the Tet Offensive before being removed from the front lines for political reasons. When North Vietnam launched the 1972 Great Offensive, he was brought back to the field and eventually promoted to commander of an Army Corps Task Force along the Demilitarized Zone.
