Each curtain has a rubber or plastic sponge pad stitched between inner and outer layers of nylon fabric, with fabric sleeves or tunnels stitched on the outside and in which an elastic cord is placed, such as a "bungy" cord. One sleeve and its enclosed elastic cord is positioned generally parallel to the front edge of the curtain, so that when the side of the plane is engaged by the front of the curtain, the front of the curtain will fold and gather against the plane. The other cord and its sleeve are arranged angularly, extending from points adjacent the ends of the front cord and a point adjacent the rear edge of the curtain at its greatest width, with the rear cord also stretching the curtain.
