1, 2, or max 4 Pings with 20mm is the End of the Fun for any Plane.
That clearly true.

40mm or 37 a single Hit is enough
1 engined Planes comes apart with a such Shell und you can collect a Jigsaw Puzzle on the Water Surface..

No, there's something wrong with the way the game was made in the first place. As I think I said earlier, in the stock game you get attacked by dozens of planes and could shoot down a bunch of them before they finally got you. The armor values are for the whole aircraft, not individual parts. The only way to make it so one plane is dangerous was to up the armor value.

Talking about how protected the pilot may or may not have been is irrelevant. What is relevant is that single aircraft attacked u-boats and sank them. Sunderlands and especially B-24s were the bane of the u-boat.

The fact is that 250 u-boats were sunk by aircraft in WW2. They shot down a lot of planes as well, but the trade-off was never worth it.

Now,explain how B-17's came back home with several machine gun and 20mm shell impacts practically everywhere and even maybe a flak round or two,or even a ramming.
I tell you,I've seen a photo where the radio room was absolutely so ripped apart by a 150mm flak round that 4 men could fit in the hole,and still made it back home.
Or maybe you mean any smaller planes.
Typhoons could also take several 37mm shells in the fuselage without flinching...or maybe simply getting the radio fried.
