The pilot will attach a supplied wooden bomb to the plane in either a cup attached to the top of the plane; or in a bomb drop device on the plane.  The scoring will be the sum of the distances from where the bomb drops and the distance to the nose of the plane where it stops from the target after landing.  If the bomb is lost in the air, then the pilots score will only be the landing and will only be compared to other fliers who loose the bomb.
