264:, "The series of aeronautical experiments upon which we have been engaged for the past five years has ended in the production of a flying-machine of the type fitted for practical use. The numerous flights in straight lines, in circles, and over S-shaped courses, in calms and in winds, have made it quite certain that flying has been brought to a point where it can be made of great practical use in various ways, one of which is that of scouting and carrying messages in time of war."

181:. The owner of the land, banker Torrance Huffman, allowed them to use the land rent-free, his only requirement being that they were to shepherd the livestock to safety before experimenting. The Wrights began erecting a shed to house their aircraft during April and by the end of May were ready to begin trials, and an announcement was made to the press that trials would begin on Monday, May 23.

aircraft followed, but the run of bad luck ended on
November 9, when Wilbur flew four circuits of Huffman Prairie, staying in the air for five minutes and only landing because the engine was beginning to overheat. On December 1 Orville made a similar flight, and on December 9 they stopped flying for the year.
184:
A crowd of around forty people, made up of family and friends and a dozen reporters, assembled on the Monday but rain kept the aircraft in its shed all morning, and when the rain cleared the wind had died away. There was little chance of a successful takeoff from the 100 ft (30 m) launching

summarized the flights, "There were 105 flights made in 1904, almost all short flights, but the longest, on

to multiply the distance that the aircraft was pulled. Launched by the apparatus, Wilbur made his first turn in the air on
September 15, and on September 20 he succeeded in flying a complete circle—the first ever by an airplane—covering 4,080 ft (1,240 m) in 1 minute 16 seconds.

Because wind strength and direction were less reliable than at Kitty Hawk, the men sometimes had to laboriously re-lay the 160 feet (49 m) of "Junction
Railroad" launch rail to suit conditions. On 7 September the men began using a catapult to accelerate the aircraft to the speed necessary for

Work on the engine and poor weather delayed further attempts until the
Thursday afternoon, when despite ignition problems a takeoff was attempted, and a flight of around 25 feet (7.6 m) was made, ending in a heavy landing which damaged the aircraft. Press reports were mixed: the

Repairs took two weeks, but the next flight attempt also ended in a crash, necessitating a further two weeks of repair work. On June 21 three flights without any breakages were achieved, but four days later the aircraft crashed again. These accidents were caused by the aircraft's
