The support beam has a coupling end and a free end. The coupling end has a pivot pin. In this manner the collapse of the beam is allowed for take off and landing of the aircraft. Also provided is a sign of a durable fabric material. The sign is adapted to display indicia. The sign has a top edge, a bottom edge, a front edge, a rear edge and a pair of faces on either side. The top edge is coupled to the bottom portion of the body of the aircraft. The front edge is coupled to the support beam.
