Santos-Dumont number 6

On October 19, 1901, Alberto Santos-Dumont flew his No. 6 from Saint-Cloud around the Eiffel Tower and back to win the Deutsch de la Meurthe prize, which demanded the round trip in under 30 minutes. His flight lasted 29 minutes and 30 seconds, although the timing was disputed at first, and he gave the 100,000-franc prize to his crew and the poor of Paris. Small, nimble and flown by its own designer, No. 6 showed a whole city that an airship could be steered to a chosen point and brought back.
