Do you have vulnerability on?

Vulnerability? How can you fit the vulnerability issue if i'm talking about AI planes that go sliding along the ground at 300Km/h and breaking into pieces?
1st of all you cant set an AI to be invulnerable and 2nd i didn't say they couldn't break apart, they can but once the sliding stops the planes don't actually stop they keep jumping and bouncing.
