Ulsterman's reference is to an event in early 1972 (probably just prior to the Easter Offensive). I was working a night shift on the radar scope at the 619th Tactical Control Squadron (my call sign was Paris 33), at Tan Son Nhut. A helicopter checked in on our frequency formally and about 2 minutes later checked out. Then about 5 minutes later, he repeated that process. Another few minutes passed and he was back to repeat this process again. On a night shift, with little happening, a controller was happy to talk to almost anyone, so I asked him what he was doing. His response was that he was "filling out Air Medals". He had been tasked to load up short-timers who were just below the required missions for their Air Medal and get them those missions. So he was taking off from one side of Hotel 3 (the helipad at Tan Son Nhut) and flying to the other side, where he landed. By checking in and out with a control center, he had completed a sortie. Everybody on board got their numbers for an Air Medal, I got credit for a few sorties controlled (among the 10,100 I handled that year), and all was well with the world. From one perspective, it was gaming the system, but it was also a case where a commander understood how things worked and took a few steps to see that his troops got a ribbon to wear home.
