Although important strides had been made toward solving the problem of control, Wilbur and Orville lacked opportunity for sufficient practice since they did not get much time in the air. There still remained much for them to learn before solving the major problems of how to (1) design wings properly, (2) control the aircraft in flight, and (3) provide power, in order to build and fly a powered machine. They knew that they must learn how properly to build and control a glider before attempting to add a motor. “When once a machine is under proper control under all conditions,” Wilbur wrote his father from camp, “the motor problem will be quickly solved. A failure of motor will then mean simply a slow descent & safe landing instead of a disastrous fall.” They looked forward to the next slack season in the bicycle business so that they might resume experiments with a new glider. _Glider Experiments, 1901_ In July 1901 the Wrights returned to Kitty Hawk during a downpour of rain immediately after a storm had broken anemometer cups at 93 miles an hour. There followed a miserable week spent fighting mosquitoes, “which came in a mighty cloud, almost darkening the sun.” They attempted to escape by going to bed early, wrapped up in blankets with only noses protruding cautiously from the folds. But the July heat became unbearable beneath the blankets. When they partly uncovered, the mosquitoes again swooped down upon them, forcing a perspiring retreat once more behind blankets. But Wilbur and Orville pushed forward good-humoredly and energetically to solve the problem of flight. During the 1900-1902 experiments, the Wright family, and the brothers themselves, considered the brother’s stay in camp at Kitty Hawk simply as pleasure trips or vacations. Everyone in the family was glad to have them go to their North Carolina camp. The advantages of the sunshine, sea breezes, and outdoor exercise outweighed occasional discomforts and seemed to be good for their health. Indeed, their sister Katharine wrote, “Will and Orv ... think that life at Kitty Hawk cures all ills, you know.” Being sons of a bishop who enjoined them “to honor the Sabbath,” the brothers did not test their gliders on Sundays while in camp. On those days they often visited with the friendly and hospitable people in Kitty Hawk, and at nearby lifesaving stations. They frequently wrote home. One of Orville’s hobbies—photography—also resulted in a fine record of the early experiments. They collected shells and went hunting and fishing. Orville observed while in camp, “This is great country for fishing and hunting. The fish are so thick you see dozens of them whenever you look down into the water.” [Illustration: Wilbur Wright gets an assisted takeoff in the 1901 glider and ...] [Illustration: ... sails at low level over one of the Kill Devil Hills.]
