wow, 15 minutes from leaving the stand until brakes released. I know the taxi routes are long at MAD, wonder if there was a takeoff queue? I was convinced one time where we had a short taxi and the HP757 was taking rwy 32L at ORD that a friendly AA F100 crew told my sleepy pilots to maybe throw down a little flap. Guess it saved them from the horn, but if it was malfunctioning.....
I always thought of other more alert crews as a bonus last safety check, but only when there's queues.
