I've heard about the professor bet he was a real intresting fella, he reminds me of a guy local to me that up until 18 months ago rode a Honda 90 at the ripe age of 97. During the war he at first flew Lancaster bombers then later was commissioned to repair and rebuild the Merlin engine until the end of the war. He is a mechanical and electrical genius, he also built a few engines in the mid 50's that raced at the Isle of Man. Sadly he's in a nursing home but in good fettle, and still keeps an eye on the results of the racing.
