The prototype Zeppelin NT (SN 01), "D-LZFN, Friedrichshafen", was intended to be used for training pilots for special flights and for presentations. During the Oktoberfest of 2002 a Zeppelin NT was used for radio experiments in connection with the European Galileo positioning system project for the German Aerospace Center and the ESA. It was intended that all further ships would be used commercially or sold. As a tribute to the days of Zeppelin mail, a number of mail-carrying flights were planned. Steve Fossett and Paul Stroehle set the current speed record for airships over a distance of one kilometer on Wednesday, October 27, 2004 in Friedrichshafen, Germany with a Zeppelin NT.
