The South Vietnamese government felt at this stage that the VNAF B-57 program should be given some more visibility, and to celebrate Vietnamese Armed Forces Day, on 29 October 1965, five B-57s from the 8th Bombardment Squadron, then based at Da Nang AB, were repainted with VNAF insignia and carried out an air strike against a suspected Viet Cong stronghold and landed Tan Son Nhut Air Base. After landing, the planes took off again and joined other VNAF aircraft in a formation flyover of Saigon. Although manned solely by American crews, this attack was heralded as the introduction of VNAF B-57s into combat.
