Did one some months back. Into LHR, we were told by ATC, "Any speed, any approach, any runway."
Car was waiting on the taxiway, dropped off the Comp A, backtracked and departed dct to home.
Its refreshing to see that there is something that we still do well, without negotiation or compromise. I'd like to think that if I ever needed it then the system would be willing to do the same for me.
