Anyone else find it quite sad that people can list every sortie a pilot flew, every aircraft they flew, intricacies of their uniform, what they ate and even what their dog was called, yet a simple question about the number and composition of groundcrew required to service an aircraft leads to replies littered with ‘I think’ and ‘probably’.

WWII groundcrew (or any groundcrew!) are a sadly neglected part of the war and the lack of information and decent books about them is a quite sad affair.

I think – as JDK and myself have alluded to previously…there are too many possible variable circumstances to give a really simple answer,any RAF Unit/Sqn would have its own local Regulations and Orders and the manner in which daily inspections/turn rounds etc were accomplished might vary considerably,and of course much would simply depend on how many skilled tradesmen were available,trade boundaries in the RAF have always been flexible and at a stroke of a pen you might find yourself ‘qualified’ to work outside your trade.
As Creaking Door posted earlier…as the war progressed some RAF units went to a more centralised system,but I would imagine there was much local variation even then.
In my ‘career’ as a Rigger…I have always been impressed by the variation in local working practices/procedures etc at the various units/stations where I have worked.
