declassification of the conversion only occurred in March, providing less than two months for open actions to implement the transition. Although the first F-105 arrived at Tinker on 14 April, the reservists were not prepared to accept the aircraft, and a special team from Tactical Air Command arrived to inspect the aircraft and place them in temporary storage until aircrew and maintenance personnel could be trained on the fighter. The following spring the Reserve reassigned its tactical fighter squadrons directly to the 301st Tactical Fighter Wing. After two years the group was once again activated. It trained for tactical fighter missions, participating in numerous tactical, joint, and combined exercises until September 1994. In 1978, the 507th became the first Air Force Reserve group to participate in a Red Flag exercise], and two years later it was the first to deploy to Turkey for its annual tour of active duty.
