When I was in, had one Lt. Col. Who flew my KC-135. He was a C-47 pilot in Vietnam. Told stories that mirrored yours. Said that they would light up the jungle. He told me about his first sortie, as they were circling, the gunner was yelling at him to continually put in more rudder. When the guns would fire, they would push or drift the aircraft itself off target. Cool stuff!Down in the Delta, before C-130's, they used C47's equipped with Gatlin guns, all mount to one side, we had to give hourly coordinates at night as Puff would make runs on Charlie. He would fly blacked out at about 1000 ft and bank the aircraft in a spiral turn and unleash hell with about 6000rd a minute out of each weapon, looked like a sheet of red rain dropping down. Thank God, I could read a map well, they would vaporize a football field area in seconds. Even today late at night, I look up waiting to hear the engines cut speed..and have flash backs when I eat rice LOL
