Now i have a helicopter with the player in it. The helicopter has a waypoint: the ground. It will crash. It works and all, but how would i make it so that when it hits the ground it goes to a different scene?

If your helicopter and the ground have colliders attached to them, you can use

http://unity3d.com/support/documentation/ScriptReference/MonoBehaviour.OnCollisionEnter.html

This function will be called whenever a collision appears and you can then check if the collision is in fact with the ground (by checking the name or tag of the other collider).

Once you have the collision, you can use this function to load another scene

http://unity3d.com/support/documentation/ScriptReference/Application.LoadLevel.html

Sth like this

void OnCollisionEnter(Collision collision) 
{
    if( collision.gameObject.name == "Ground" )
    {
        Application.LoadLevel( "youAreDeadLevel" );
    }
}
