During the attempted landing by Jolly Green 43, fire was seen coming from a semi-submerged Swift Boat that had been shot up by an AC-130 the previous day, A-7 aircraft were called in to destroy the boat with their 20 mm cannon. At 16:20 hours, Nail 68, an Air Force OV-10 forward air control (FAC) aircraft, arrived and took over the direction of air support. At 16:23 Nail 68 called on Wilson to use its 5-inch gun to destroy the semi-submerged Swift Boat.
