Mine's long gone into the mail.
SteveR is absolutely right - the more letters, especially subtly different ones, received, the more our arguments have to be listened to.
You may be sure the antis/trolls/AEF and the like will be doing their darndest to ensure nobody gets to fly. And there are a heck of a lot less of them than there are of us pilots.
Trouble is, while we're up flying and having fun, they are down in their dumps writing letters to try to get us stopped.
