Bristol Frightener
For me, the ODDEST was the Bristol Freighter. Not only the oddest, but also the dirtiest. Powered by two Bristol Hercules 2000 HP Oil Pumps they leaked as much oil as they burned. Remember a Nav being a bit anxious to open the clam-shell doors while still taxying. Result, two chopped up doors and two damaged props. Maybe he was affected by the Carbon Monoxide which used to leak into the cockpit area through the wing roots.
