The Vienna (Virginia) Wireless Society has had several balloon launches. Our last, on May 1, 2010 reached 117,877 ft. We use a Garmin GPS-18, which works at these altitudes. Information on our flights can be found at <http://www.viennawireless.org/balloon/missions/>, and some pictures from the latest flight are at <http://www.wherry.com/photos/2010-05-01-balloon-vws8/>.
