An old SAR pilot with a royal surname once told me about a ferry flight of 5 Wessex from here to Cyprus many moons ago. Apparently two of the aircraft made it more or less as planned, another two experienced some problems but turned up within a reasonable timeframe, and the fifth one took 67 days to complete the journey! Perhaps someone can elaborate?

There's a remarkable account of one man's experience of this, flying a Hurricane, in 'Out Of The Blue' by Laddie Lucas. Well worth seeking out if possible.
