Speaking of Merlin engines and Spitfires, I once lent out a book with a whole bunch of Pilot Officer Prune cartoons in it from WWII era, but never got it back. I always thought those cartoons were excellent. The book had an excerpt from the RAF Pilot's handbook from the mid-1930's which stated something like 'if you are to crash land - pick the softest, cheapest crash site'.
Pilot Officer Prune says 'A good landing is one you can walk away from'.
