Tac,
I nailed a P-51D's wing with my Lanc's top turret yesterday. Probably hit the wing with a good 25-30 rounds. You know what happened? Nada, zip, nothing. That's what happened.
If a Lanc's top, or nose, turret can blow a fighters wing off when the fighter does a high speed slashing dive, I'd love to see it because, frankly, I don't believe it. I bet the twin 50s in the tail were involved as well as a good dose of luck on the part of the Lanc.
