Hurricane and Mossie were both capable of absorbing lots of damage. In the Hurri's case because much of the fuselage was fabric covered and canon shells would pass clean thro without exploding.
In the Mossie's case, it was one of the first monocoque (stressed skin) a/c and could survive big holes being punched in the wings.
But with the uberack in AH....
Btw, is there any chance of the AI giving me some tips on how to shoot in an Ostwind?
