A banner (1) which can be dragged by an airplane (2) by means of a drag rope (3), comprising a banner rod (5) which is connected to the drag rope (3) by means of a banner spider (4). Disks (10) acting as trailing wheels are arranged on the banner rod (5) on both sides of the banner (1). The banner r od (5) is held at a distance from the surface of the runway prior to starting off, such that the banner does not lie on the runway as a result of the wind produced by propeller of the airplane (2), thereby enabling the airplane (2) to start off with a coupled banner (2) without any problem.
