On 2 July 2000, the centennial of the first Zeppelin flight, the prototype was christened "D-LZFN Friedrichshafen" by Count Zeppelin's granddaughter, Elisabeth Veil. In July 2000, the prototype performed a high-profile tour of Germany, travelled more than 3,600 km (2,237 miles) in about 75 flight hours and appearing at the Expo 2000 at Hannover. By December 2000, the flight test programme was completed; during which, the prototype had accumulated in excess of 800 flight hours over roughly 220 flights. In June 2001, the prototype appeared at the Paris Air Show, the occasion being the first time that a Zeppelin had cruised above Paris since the 1920s.
