A Royal Thai Air Force North American T-28D Trojan is also waiting for take-off. The black-bellied F-4D 66-8738 was equipped with AN/ARN-92 LORAN-D equipment (note antenna) and was one of only two F-4Ds fitted with the AVQ-11 Pave Sword precision attack sensor. However, it was shot down by a North Vietnamese Mikoyan-Gurevich MiG-21 with an Atoll-missile on 5 October 1972. The crew was taken prisoner but was released in 1973. The Thai T-28D (former U.S. Navy T-28B, BuNo 137802) was preserved at the RTAFB Phitsanulok, painted as "46101".
