It is a no fly zone, unofficailly. What's really wierd is that it does not happen all the time. I've seen people get gutsy and fly in the same place where I lost mine and nothing happens. However I have seen people fly in a different place than I lost mine, and they lose theirs. I know there's not always an explination. I got my plane back and everything worked. There was no other radio at the field that day on my frequency, and my batteries were still charged. And since there are so many stories about the building, I'm sure it has something to do with it, sometimes.
