ABSTRACT:
A location and signaling balloon device includes a lifting body balloon, a pressurized vessel of lighter-than-air gas and tethering apparatus for an inflated balloon. The tethering apparatus includes a tether line wound on a friction spool which is attached to a necked-down portion of the pressurized vessel. The friction spool prevents the tether line from freely paying out and snarling.
