Still waiting for this to happen:
"Airline XXX this is Joe Smith, I will be your Air Traffic Controller for this vectoring for ILS APCH RWY10, the weather today is fine with....."
Than after you're established:
"Airline XXX how do you rate this vectoring for the final?" "Contact TWR, it's been a pleasure "flying with you", hope you'll choose us next time for your vectoring."
What's the history behind "captain" on an aircraft? I fly a Piper in my sparetime, am I a "captain"? As far as I'm aware most CAA's refer to "Pilot in command", not "captain".
