There have been a lot of very polite answers so far. I am not ATC (married one though).
On some occasions the answer has got to be YES.
As you must have listened to yourself there are some wonderful "funnies" broadcast, but there are some cringe-making, embarassing to listen to, howlers where the individual is simply just too ignorant of the correct basic procedures / phraseoligy to be allowed out with an aircraft. I do not mean the new PPL / trainee who is just making an honest error through lack of experience. What really grips my s~~t is the can't be ar~~ed to learn to do it better dudes
. To put my mini-rant into perspective - yes I am a pilot, thousands of hrs (mil and GA) and I fly for the fun of it and firmly believe that the R/T should be used as often as possible where it can provide a service / improve awareness.
