Indicates that a lot of the 'damage modelling' is visual and not reflected in the flight model.
I'm sure it did fly...but it shouldn't have.
But the visuals are good - I was going to say there should be a wing spar running out of that damaged wing, and a failure of the spar should have caused the wing to fail, but actually it looks right
This article shows the Hurrican wing construction, matches CloD.
