Oh, I remember one time waiting with running engine for our gate at T4 to be cleared. It was occupied by a BA 744 which was obviously ready to be towed but according to GMC BA had no tug. While waiting though (for 45 minutes !), we could see several other BA aircraft towed away from their gates just in time for another Speedbird (which all had just touched down) to dock.
Still waiting for my chance to send a Speedbird in the G/A, just to make things even
