During all their experiments at the Huffman pasture they had continued to ride “belly-buster,” as a boy usually does when coasting on a sled. Lying flat in that way and controlling the mechanism partly by swinging the hips from one side to the other was good enough for the experimental stages of aviation; but the Wrights knew that if a plane was to have practical use the pilot must be able to take an ordinary sitting position and do the controlling and guiding with his hands and feet as in an automobile. It was not all fun lying flat for an hour at a time with head raised to be on the lookout for possible obstacles. “I used to think,” said Orville in later years, “the back of my neck would break if I endured one more turn around the field.” The brothers therefore had adopted a different arrangement of the control levers, for use in a sitting position, and a seat for a passenger. Moreover, the machine could be steered from either seat and thus was suitable for training other pilots if occasion should arise. The plane sent to France for possible trials in 1907 was thus equipped. They revamped the machine they had used at the Huffman pasture in 1905, and installed their later improvements. It now had an engine with vertical instead of horizontal cylinders. With this machine they would go to Kitty Hawk and gain needed practice in handling their new arrangement of the control levers. The United States Government tests would be made at Fort Myer, Virginia, near Washington. Delivery of the machine had to be made by August 28, and the tests themselves were to begin shortly afterward, in September. But at about that same time, one of the brothers would make a demonstration in France. They had not yet decided which of them would fly at Fort Myer and which should go to France. But both had to be well prepared and there was no time to lose. They must be established at Kitty Hawk as soon as possible. Wilbur Wright set out for Kitty Hawk ahead of Orville and arrived there April 9, 1908. He was joined within a week by a mechanic from Dayton, Charles W. Furnas. First of all, it was necessary to do much rebuilding of the camp. The buildings had not only suffered from storms, but had been stripped of much timber by persons who supposed the Wrights had permanently abandoned them. The plane was shipped in crates from Dayton April 11, but had to be left for some time in a freight depot at Elizabeth City until the new shed was completed at Kitty Hawk. Both Orville and the plane reached there on April 25.
