I'd like to know how 617 coped with the sudden and relatively brief use of Mosquitos and a Mustang, from a servicing point of view. Did they simply "borrow" 627 Sqn ground crew for the Mossies? How did they deal with the Mustang (used by Cheshire)?
Did they need to get factory mechanics for the modified Dambusters machines, or were they dealt with by the squadron ground crew?
How much contact did the ground crew have with the flying commanders? Did they feel like mushrooms (kept in the dark and fed ____), or were they kept "in the loop"?
How much contact with flying personnel beyond handing over the aircraft and accepting it back? Pub crawls together? Hit the town together?
Were some aircrews harder to work with than others? What made the difference? What did flying crews need to do to get the best from the ground crews? (Did they even work more with some crews than with others, or was it just "Today do A-Apple, tomorrow Q-Queenie"?)
Was morale an issue for groundcrews? What kept it high or brought it down?
High points in his / the squadrons career? Low points?
Return to civilian life: something to be dreaded or something looked forward to? Easy-peasy or hard?
Any decent books by ground crew (beyond his own)? I sure as heck can only find rare glimpses into groundcrew experiences on Mossie squads.
Were there civilian contractors from Avro etc on the field for heavily-damaged aircraft? If so, did the RAF guys have any contact or was it separate worlds?
I occasionally read about "rogue" aircraft, very difficult to handle in the air. The 23 Squadron blog even states fairly plainly that one of their Mossies was so intensely disliked that it was deliberately belly-landed so crews didn't have to fly it any more. Did he encounter such aircraft? Views on why they were so?
Were there any issues regarding the aircraft and their handling which made the ground crew guys feel they were just

? Could they make their views heard up the chain, or would that have been pushing ____ uphill?
Did he go on a "Cook's tour" at the end of the war? If so, impressions?
Were ground crew given regular leave in the same way as aircrew, or were they more or less permanent fixtures?
Were experienced guys sent off to new squadrons as the bomber force grew, or did they stay with their original unit?
What was their "unit" affiliation anyway? Flight? Squadron? Airfield? Station? Group?
Spares/stores situation? Did they have what they needed or did they have to pilfer from one aircraft to the next, squirrel stuff away?
I've read, in the appendices to one squadron's ORB, of ground crew being put on a charge for misplacing "bits", one poor fellow even had his pay docked for quite a substantial amount. Was this common practice, or only for repeat offenders, or did it depend on the local chain of command?
If the ground crew organisation had been his to set up and run, how would he have done it differently?
All I can think of right now.
