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 indicators would be useless) and direction. The combined mass of an average system can be calculated as follows: using a density of 0.9486 kg/m³ for dry air heated to 210 °F (99 °C). Increasing the air temperature inside the envelope makes it less dense than the surrounding (ambient) air. The balloon floats because of the buoyant force exerted on it. This force is the same force that acts on objects when they are in water and is described by Archimedes' principle. The amount of lift (or buoyancy) provided by a hot air balloon depends primarily upon the difference between the
