Flying Tiger Line adopted the Canadair CL-44 swing-tail aircraft in 1961, becoming one of the first carriers in the world to offer aerial pallet shipping service. In 1965, Flying Tiger Line began operating jet aircraft when on September, 27, the first (as N322F) of four Boeing 707 was delivered. The Boeing 707 remained in the fleet only few years, and later sold, upon arrival of the higher-payload Douglas DC-8, the largest civilian airliner until the Boeing 747 entered service. The first Douglas DC-8-63F registered as N779FT was delivered to the airline on June 26, 1968 and the other eighteen followed until 1972.
