During my training at a certain London airport with 2 runways I was told not to use "follow" on GMC because pilots might take this a bit too literally and follow the a/c all the way to and possibly on to the runway-I know this sounds a bit far fetched (but I saw it happen (and was duly b@*?cked by the Deps controller!)) and in the context of this thread is obtuse but if we can't credit pilots with at least a little common sense and accept that some will occassionally try and extract the michael then we may as well start moving one plane at a time!! If someone tries it on with me, then for about the next 2weeks that operator tends to be No. 2 when all other things are equal; unprofessional and petty maybe but it serves to balance the scales for those who do do things properly!!
