Unfortunately you lot have picked a day to which I cannot attend.
However I will be at Heathrow Airport until 12 midday on June 12th, then if you see an American Airlines 777 take off that'll be me on my way to San Diego (via New York).
Heathrow ATCO's probably work unlike Cardiff Tower, or should that be "Cardiff Flower"? Flower will know the joke there... ;-)
Okay before I get flamed, I know Cardiff ATC do work very hard, but, well... flower do you want to comment? ;-)
