A welcome sight to jet fighters low on fuel is this Marine KC-130F Hercules of Marine Refueler Transport Squadron 152 [VMGR-152], with refueling hoses extended, somewhere over the South China Sea. It’s mission: to refuel thirsty jets returning from strikes over Vietnam (official USMC photo by 1st Lieutenant Joe Collins).
