Abstract
A non-rigid aerodynamic balloon having integral stabilizing tail fins is provided. The balloon is most useful in tethered applications, such as for advertising. The balloon is formed from a plurality of flexible skin-like gores which are joined together with a plurality of longitudinal seams running lengthwise of a main body of the balloon. Each gore is a continuous piece of flexible skin-like material which forms a portion of the body and a side wall of one of the stabilizing fins. The longitudinal seams join adjacent gores along outer edges of the stabilizing fins so that seams are not required to join the stabilizing fins to the main body of the balloon.
