Abstract

Disclosed herein is a method and device which provides for the capability of functional illumination by a balloon. This invention includes one or more fiber optic elements within a balloon which are configured to disperse substantial light at its (their) ends. This invention further provides for reliable retraction of signal or illumination balloons during hazardous wind conditions by including a sensor for detecting the presence of such conditions, and providing for retraction of the balloon via its tether, wherein such retraction is either under operator control or automatic.
