I really sympathize with Flying Tiger. It's really painful when you lose your pride and joy, especially if you have nothing else ready to fly. But I have to go along with Redneck Shaun here. If you have a frequency board and people flying, then by all means, you should have your pin or card displayed so there is no mistake what frequecies are being used at the time. The kind of thing that scares me is what happened at our flying field last weekend. It was late afternoon and three of us were there. One was flying. I was busy filming his flight. I overheard the third guy talking to somebody that had pulled up in his vehicle. I heard him ask the guy something about frequencies, but didn't pay much attention, figuring he had it handled. Later, the guy told me that the stranger had pulled up about 50 feet away. He had pulled out a small electric full-bodied foamy, and immediately turned the radio on. Fortunately, the guy didn't shoot anybody down. When asked what frequency he was on he responded, "Frequency, what's a frequency"? Turned out that he had flown a few times, a couple years ago, with a guy way out in the country. They had never discussed frequency, so this guy had no idea of frequency protocol, even though it was clearly explained in the manual for the new foamy he had. We explained it to him, so I'm hoping that the next time he shows up there, or at another flying field, he will ask around before he starts turning on his radio. The thing that scares me is that this kind of thing can happen anywhere, regardless of the frequency board, how strictly it is adhered to, or how prominently it is displayed. If this kind of thing happens, and the guy shoots down a $5,000 plane, do you think he is going to pay for the plane? I don't think so. This guy has spent $160 at a department store, buying a toy for his son, and he looked until he found what he figured is a suitable place to try it out. Not very likely is he going to feel sufficient responsibility to pay for a $5,000 plane. The owner is just out, regardless of how upset he gets or how much the other fliers side with him. After a short discussion, we decided that every time a stanger pulls up, we need to immediately approach him to see what his intentions are. We intend to be friendly, of course, but we intend to do all we can do to prevent a repeat of what happened last weekend. No harm was done, but the potential was certainly there.
