I found a clip once on utube it had I think a resto going on with an ME-109 engine they sent the crank to Rolls Royce to check the engine out. Nope I remember now it was on the history channel Wings of the Luftwaffe.The chap from Rolls Royce who was tasked with the engine said on film he cautioned the people working on the plane not to damage the crankshaft.
Why you ask? he said during the war Germanyproduced about 20,000 engines for 109's all the while being bombed 24/7 allowing for weather interludes. The spokesman said its tolerances were smack bang in the middle of what they should have been and if you break it we cannot produce another one. I put the ME 109 main gear in the same realm as the ME-262 nose wheel as I wonder how many 262's collapsed being towed by a Kettenkrad over the airfield.
Until they figured on a system that evened the load from the nose wheel onto the main gear even then they had to be careful.
Of all the books I have read on both sides of the conflict some chivalry did exist between fliers the love of flying, seldom have I read where they deliberately targeted the pilot.
Most of the Schrage Musik night fighters went for the wing tanks on the bombers though I am not saying there weren't pilots who deliberately concentrated their fire on the canopy.
Some top Britishaces thought only to bring the plane down and not think about the pilot.
Just recently on our news an AustralianWWII bomber pilot had written to certain towns in Europe apologizing for the civilians he killed whilst bombing the cities.
It had been troubling him very much over the years, all the cities wrote back from Germany thanking him and they understood that at the time he was carrying out his duty.
The plan was called "Point Blank" it is contained in a 3 volume set The air offensive against Germany it was derived at between the powers that be.
With Winston and Bomber Harris pushing to bomb the civilian population to make them lose faith and their support in the continuation of the war.
