<<Air France to ATC: "What iz zee reason for ze delay?"
ATC: "Aeroplanes">>
That was always my response 30 years ago!!
If Virga flies big jets there obviously is no reason why he should be delayed for a clockwork mouse...
<<why should we worry about when the other aircraft get to go?>>
But pilots DO - they jolly well DO; "Why is Speedbird going ahead of us?", etc, etc.
