I saw a British test video of a 20 mm ff canon doing just that. Breaking a spitfire's main spar.


Yes, thanks Brealistic, that is a pretty interesting link. Good find.

Your very welcome buddy

The test was done right at the wing root and took the wing off. The 20 mm is a "mine shell" It's thin walled and filled with explosives.
