A magnificent job which I think can only be fully appreciated by another mechanic.
One question which always puzzled me> Why did they opt for contra-rotating props on the Shackleton? Not needed for torque problems as in a single-engine aircraft. Surely, it would have saved considerable weight in the engine gearbox and prop to go to a single prop. If fuselage or ground clearance was an issue I would have thought a four-bladed paddle-bladed props serve. All that takes nothing away from a truly unique aircraft.
