The revolution in air transport in four dates: naturally 7 December 1903 and the first flight of the Wright brothers; 6 October 1973, during the Yom Kippur War, the first use of a military drone (Unmanned Aerial Vehicle – UAV), the Tadiran Mastiff; 21 October 2011, with the first piloted flight of the German start-up Volocopter’s Vertical Take-Off and Landing (VTOL) prototype; and lastly, a number of dates between June and September of this year when no fewer than thirty companies (30 selected out of 150 candidates!) will engage in Urban Air Mobility (UAM) tests over Paris. More specifically, the testing will take place at the Pontoise-Cormeilles Aerodrome, north-west of the French capital, with a view to establishing one of the world’s first air taxi services in time for the 2024 Olympic Games. The Games will be the grandstand for a service much desired by the Mayor of Paris, Anne Hidalgo, to connect the Charles De Gaulle airport to the city centre and the Olympic venues. The service will be managed by ADP, which manages the Parisian airfields, together with RATP, which handles local transportation, and the development agency Choose Paris. The three had worked extensively on regulations, which, together with the physical spaces where these vehicles will operate, are essential for the development of a market reputed by many analysts to be worth billions. Asian megalopolises and, with an eye to possible acts of terrorism, their U.S. counterparts are very interested in a sector that Morgan Stanley estimates could be worth more than a trillion dollars by 2040. But this time, Europe does not want to stand idly by on the side-lines. New projects are announced one after another: from Spain to Germany, and from Holland to the British Isles. While less grandiose, Paris has announced tests by SESAR, the European air traffic control research programme, of projects by various operators who have thrown their hats into the ring.
