ABSTRACT:
The present invention relates to a device for use on airplanes to permit visual identification and location by pilots of other aircraft in the vicinity so as to avoid mid-air collision. The device receives light from any light source and reflects it to all points within at least a defined hemispherical area normal to the device, so as to make the plane visually observable by pilots, any other aircraft in the area. The device is formed as a tape and attached to various parts of an aircraft. The reflecting elements redirect and intensify each light source creating a readily recognizable shimmering image.
