You do it infrequently and when you're scheduled to do it.
Well, once or twice a day - not record-breaking, but not infrequent either. And I always get the casting vote in both when I fly and what type of sortie I do, as well as being able to generate sorties on my own behalf if I'm not doing enough flying already. Please don't tell me that this is not the case - the fact that you can't comprehend my freedom of action, or the enjoyment it gives me even after 20 years in, says more about you than me. In the rotary world, this is now (with the demise of the UK SAR Force) unusual, but I find much the same at the AEF where anyone can enjoy the same (sure, the range of profiles is somewhat more limited - just flinging the aircraft around the sky again and again...).
In the unlikely event that anyone is still reading this thread, I would simply say that to me it is still fun, in particular since many of the bitter blinkered has-beens like Prooney (callsign Wayne?) have long since f**ked off to sulk somewhere else.
