Aviation in France The national carrier of France is Air France, a full service global airline which flies to 20 domestic destinations and 150 international destinations in 83 countries (including Overseas departments and territories of France) across all 6 major continents. The history of French aviation began at the beginning of the 20th century. The French had been involved in human flight since 1783, when François Rozier and the Marquis d'Arlandes flew over Paris in the first human flight in a Hot air balloon. On 7 January 1785 Jean-Pierre Blanchard crossed the English Channel, from Dover to Calais, on board a hydrogen balloon.
Hot air balloon course) stated in the previous section. Liftoff would require a slightly greater temperature, depending on the desired rate of climb. In reality, the air contained in the envelope is not all the same temperature, as the accompanying thermal image shows, and so these calculations are based on averages. For typical atmospheric conditions (20 °C, 68 °F), a hot air balloon heated to (99 °C, 210 °F) requires about 3.91 m³ of envelope volume to lift 1 kilogram (62.5 ft³/lb). The precise amount of lift provided depends not only upon the internal temperature mentioned above, but the external temperature, altitude above
