Al was a Flight Commander on No 1(F) Sqn at the time of the Tower Bridge incident. Following the feat he then returned to West Raynham leaving an angry trail of complaints behind him from the airfields in East Anglia which he had 'taken out' inverted at about 200 ft on his way home. His rejoin at Raynham was from an inverted run-in to the break from about 200 ft. The painting of the event used to hang in the 1(F) Sqn museum, and probably still does.
