I have heard of the fire hose treatment for retiring pilots. (it's for their last flight) They get cooperation from the firetruck to hose down the outside of the plane, specifically towards the nosecone/windshield area. I am not sure of the origin or significance but it would sure be interesting to find out. Perhaps it's something like cutting off the shirt tail of the pilot when he/she first flies solo.
