好好学学英语Chapter 1: Brief History of Aviation
First Flight On December 17, 1903, Orville and Wilbur Wright capped four years of research and design efforts with a 120-foot, 12-second flight at Kitty Hawk, North Carolina - the first powered flight in a heavier-than-air machine. Prior to that, people had flown only in balloons and gliders. The first person to fly as a passenger was Leon Delagrange, who rode with French pilot Henri Farman from a meadow outside of Paris in 1908. Charles Furnas became the first American airplane passenger when he flew with Orville Wright at Kitty Hawk later that year. The first scheduled air service began in Florida on Jan. 1, 1914. Glenn Curtiss had designed a plane that could take off and land on water and thus could be built larger than any plane to date because it did not need the heavy undercarriage required for landing on hard ground. Thomas Benoist, an autoparts maker, decided to build such a flying boat, or seaplane, built for a service across Tampa Bay called the St. Petersburg-Tampa Air Boat Line. His first passenger was ex-St. Petersburg Mayor A.C. Pheil, who made the 18-mile trip in 23 minutes, a considerable improvement over the two-hour trip by boat or 12-hour trip by rail between the two cities. The single-plane service accommodated one passenger at a time, and the company charged a one-way fare of $5. After operating two flights a day for four months and carrying a total of 1,205 passengers, the company folded with the end of the winter tourist season. World War I These and other early flights were headline events, but commercial aviation was very slow to catch on with the general public, most of which was afraid to ride in the new flying machines. Improvements in aircraft design also were slow. However, with the advent of World War I, the military value of aircraft was quickly recognized and production increased significantly to meet the soaring demand for planes from governments on both sides of the Atlantic. Most significant was the development of more powerful motors, enabling aircraft to reach speeds of up to 130 mph, more than twice the speed of pre-war aircraft. Increased power also made bigger aircraft possible. On the other hand, the war was bad for commercial aviation in several respects. It focused all design and production efforts on building military aircraft. In the public's mind, flying became almost totally associated with bombing runs, surveillance, and aerial dog fights. In addition, there was such a large surplus of planes at the end of the war that the demand for new production was almost non-existent for several years - and many aircraft builders went bankrupt. Some European countries such as Great Britain and France nurtured commercial aviation by starting air service over the English Channel. However, nothing similar occurred in the United States where there were no such natural obstacles isolating major cities and where railroads could transport people almost as fast as an airplane, and in considerably more comfort. The salvation of U.S. commercial aviation industry following World War I was a government program, but one that had nothing to do with the transportation of people.
