Danny, your latest post perfectly illustrates the value of this thread, for not only do we get the main story (of your WWII experiences) but get to learn the mechanics of operational flying (in this case dive bombing) from someone who did it for a living! As for "out of hand", you alone are the decider of its pertinence or not. As a captivated recipient I am forever grateful for the "By the way..." asides that put us in your aircraft, in your basha, or even your charpoy (figuratively speaking of course, you understand!)
As to Captain Brown, indeed a renowned and respected aviator. Is it possible that the Vengeance that he tested was the A-35 and not the A-31? The latter, with its zero incidence wing, was the superior dive-bomber you tell us because it could indeed deliver from a 90 degree dive.
Did the Stuka share this attribute, or did its "automatics" somehow override the tendency to "track" horizontally towards the target rather than diving vertically on it? If so how could it overcome its own intrinsic aerodynamics? I understood that the automatics only extended to bomb release and recovery, or were there other features? We are all ware of the vulnerability it suffered in a hostile air environment, but when the Luftwaffe had air superiority it was a truly devastating and highly accurate weapon system.
