Seeking sustainable space flight
Orville Wright's famous flight at Kitty Hawk, North Carolina, on 17 December 1903 did not take long to inspire the public's interest in aviation. Between 1908 and 1910, about 1000 new pilots were trained around the world, and by 1912 there were almost 200 different makes of aeroplane. In the 1920s the flying community entered a golden age during which aviation switched from a largely experimental activity to a widely accepted means of transport. Aircraft such as the DC-3 were soon developed, and the foundations of the present air-traffic control system were created. In short, aviation became a commercially sustainable industry.
