Be nice to see the odd aircrew in ATC too because, with great respect, most pilots don't understand our Black Arts. During 31 years as a Heathrow controller I saw less than couple of dozen crews in ATC, and several of those were foreign. Where I worked abroad, local pilots regularly visited ATC so most of them understood what we were about..
