Bristol Type 170 Freighter Mk 31
Deployed for heavy-lift cargo operations to conquer the rugged terrain of the New Guinea Highlands, transporting bulky freight such as trucks, bridge girders, bulldozers, and heavy machinery that exceeded the capabilities of the Douglas DC-3. The aircraft were eventually withdrawn in 1967 after the completion of major infrastructure projects and sold to Air Express.
