I understand what you are asking for, but in your initial post, you only make reference to your wing being shot off.
Correct me if I am wrong, but I don't think that the JUG had any armor in it's wings and 6 .50 cals, at convergence, on a P-51, will slice just about any wing off. So, asking for more armor will not fix your wings being sliced off.
While Armor wasn't present, it was a very, very strong structure. Guys rant into telephone poles and brought back pieces with 'em.
Engine and Pilot armor however really do need to be looked at, as well as self sealing tanks.
But, as the game is, you're right- he talked about a P51 takin his wing off.
Kinda brings up the whole "new damage model" argument. We've been forever playing with ailerons, wings, elevators all popping off and not really trying to recreate damage as it happened.
Some argument could be made for "gameplay consilation", but I think gameplay could be vastly improved.
Rather then have the items "pop off", could we possible have them "damaged" to the point of not working?
Wings would still pop off if catastrophic damage occured, though.
What I'm imaganing is, here's Pannono in his Jug, he gets bounced by a P-51. The P-51 gets a very good shot at convergence at the wingroot- which buckles under the pressure and rips free.
Alternatively, the P-51 fires outside of convergence, and peppers the entire wing with just a series of pings, however 10 bullets find their way into the flap.
When the pilot next lowers that flap, the flap doesn't work and you get the same effect as in game currently.
What I'm thinking of is planes belching smoke and fluid, and losing control rather then planes losing entire parts of their superstructure.
Also, if you kill the pilot, why not keep the plane around rather then having it just "pop"? Why not let it fall to ground?
