I found that if you do the /hide animation, which is provided in gl_actions.pwn, inside a plane, you won't die if you crash your plane to explode. However, your camera will be fixed at the plane's position, and your character will disappear too.

Edit:
I know I can script it to stop people from using that animation in vehicles, but it also has bug when you do that animation and use /kill to commit suicide. You won't have the death screen.
