National Liberation Front soldiers stand guard on captured VNAF C-7A Caribous belonging to the VNAF's 431st Transport Squadron based at Da Nang. This photograph was taken at Phu Cat air base in March 1975. C-7B s/n 63-09741 can be clearly seen. The planes are not in flyable condition as evidenced by the lack of engines, missing stabilizer control surfaces, and sealed windows. (photo: Kiem Collection)
