(Ex mil now civvie). Trouble is, a lot of folks are taught more or less what to say
but they AREN'T taught what NOT to say.
Yesterday was a bit of a 'mare on the R/T, especially Coventry and Luton as it was extremely busy and very difficult to get a word in edgeways. However, a lot of transitting pilots seemed to be competing to tell ATC just about everything apart from the colour of their socks.
E.G. "G-****. I have now just seen two aircraft pass on my left hand side!" (Under a FIS in Class G).
I wasn't alone in saying "Fer Christ's sake, shut the F*** up!" or "Yes, very nice, thanks a lot for telling us that" more than once without pressing the button.
