This was on this kind of flying you really appreciated a competent navigator...Dead Reckoning skills have a tendency to become scarce in the western part of the world, due to abundance of navaids but in large land masses like Australia, Africa or South America, and the north and south poles, this is the only way to get home if your GPS is letting you down...

Thanks for the info. I have tried my best to research the map. Many of the flights are from Hemswell so this map is either from a time when Hampdens were being flown out of there by RAF or maybe Wellingtons possibly by a Polish squadron.

One day I will travel down to the museum and ask them.
