How to make a plane crash into the ground?

I want to let my plane crash in the ground after it reaches 0 health.
I have no idea how to make my plane crash into the ground. Disabling the movement etc isn’t a problem but making the plane fall like a bad paper plane is bit hard and i have no idea how to do that.

My plane also flies thru walls.


With PlaneMesh i make my plane move like this:

Have you tried to applied mass, then active gravity when plane reach 0 health? Bigger mass = heavier. You should also consider block or limit your control when it falling.
Ps: nice plane, nice control mate, really impress with the clip.

Thank you (^_^)
