OxfordFlyer, an excellent post.
I hope some of the anti brigade read it and realise that the world doesn't revolve around their monstrous egos!
The only time I've ever had call to do something about a transmission on 121.5 was when we heard an EPIRB signal whilst over the North Sea. It turned out to be nothing and had already been reported by other traffic, but it shows it pays to listen out!
Hearing practice pans etc. is just part and parcel of life. Getting steamed up about it is totally unnecessary, if listening to a few practice pans is whats required to get people happy using D&D, then so be it. It's a small price to pay.
