As Wilbur Wright watched his brother Orville guide their flying machine into the air, the past and the future separated and the world started shrinking. At Kill Devil Hills, the thermometer hovered around the freezing mark, and a mile-per-hour kilometer-per-hour wind blowing out of the north made it feel even colder. Orville and Wilbur Wright had a few doubts about whether this was a good day to try to get their flying machine off the ground. They'd had one setback three days earlier when Wilbur lost control of the craft as he was trying to take off, damaging a wing.
It had taken them a day to repair the damage and get ready to try again, but on December 16 the winds had died to almost nothing and they decided to wait another 24 hours in hopes it would pick back up. Now, with the wind blowing at a strength that could cause them problems trying to control the flyer, they pondered whether to pack it in for the season and come back next year to resume their efforts.
But they didn't want to go back home to Ohio without knowing once and for all whether this design was going to work. So they decided that this day was as good as any to give it one more shot. The Wrights hauled their wood-metal-and-muslin flyer—which resembled a box kite with propellers—out of its hangar and hoisted a red flag at their camp to signal the nearby U. Lifesaving Station that they'd like some help getting the flyer into position.
The modest, hardworking Midwesterners had formed a bond with the taciturn inhabitants of the remote, sparsely populated islands, and they'd had no trouble recruiting willing helpers in the years they'd been coming to the Outer Banks to develop their flyer. In December , the industrialized world moved at the speed of a steam engine, and lots of people thought that was fast enough.
A few months earlier a smug American scientist claimed to have proven that a powered aircraft would never fly, despite the dogged efforts of several would-be aviators besides the Wright Brothers. The scientist's opinion seemed to be confirmed a little later when a motorized flyer designed by Samuel Langley, Secretary of the Smithsonian Institution, plunged into the Potomac River in Washington, D.
Men wore bushy handlebar moustaches and stiff, high-necked collars in and wouldn't have stepped outside without donning a derby or perhaps a top hat. Women wore high-button shoes and ankle-length skirts, and no self-respecting female would dare go out in public unless her hair was properly pinned up and she had a hat on her head.
The Wrights and their five accomplices pulled the flying machine from the hangar to a specially designed wooden track the brothers had built to launch the flyer. They cranked up the four-cylinder gasoline engine that had been especially designed and built for the flying machine. Orville, at 32 the younger of the pair, was at the controls. Wilbur had won the toss of a coin to see who would go first a few days earlier, the 14th of December—but the initial attempt had failed and the flyer was damaged without leaving the ground. The Wrights stationed John Daniels at the Korona V camera they'd brought along to document their flying experiments.
They'd chosen an excellent instrument to record their work. The big Korona, which the brothers had mounted on a tripod, looked cumbersome and unwieldy but it was one of the best cameras of that era. A few minutes past a. Orville climbed onto the lower wing of the flyer, lay stomach-down across it and grasped the controls.
True to the no-nonsense demeanor of his times, he wore a dark suit, a white shirt with a stiff collar, a necktie and a cap. Wilbur, dressed almost identically to his brother, stood by holding the tip of the lower right wing, ready to steady the flying machine as it moved down the wooden track. He turned to look at the five witnesses and was dismayed to see the glum expressions on the faces of the stoic islanders.
Above the noise of the puttering engine, Wilbur asked the somber men to "not look so sad" and to "laugh and holler and clap" and "try to cheer Orville up when he starts.

They played and experimented with it extensively and even built several larger copies of the device. They also had some experience with kites. But not until , prompted by the widely publicized fatal crash of famed glider pioneer Otto Lilienthal, did the Wrights begin serious study of flight. After absorbing what materials related to the subject the brothers had available locally, Wilbur wrote to the Smithsonian Institution on May 30, , requesting any publications on aeronautics that it could offer.
Shortly after their receipt of the Smithsonian materials, the Wrights built their first aeronautical craft, a five-foot-wingspan biplane kite, in the summer of The Wrights chose to follow Lilienthal's lead of using gliders as a stepping stone towards a practical powered airplane. The kite was built as a preliminary test device to establish the viability of the control system that they planned to use in their first full-size glider. This means of control would be a central feature of the later successful powered airplane. Rather than controlling the craft by altering the center of gravity by shifting the pilot's body weight as Lilienthal had done, the Wrights intended to balance their glider aerodynamically.
They reasoned that if a wing generates lift when presented to an oncoming flow of air, producing differing amounts of lift on either end of the wing would cause one side to rise more than the other, which in turn would bank the entire aircraft. A mechanical means of inducing this differential lift would provide the pilot with effective lateral control of the airplane. The Wrights accomplished this by twisting, or warping, the tips of the wings in opposite directions via a series of lines attached to the outer edges of the wings that were manipulated by the pilot.
The idea advanced aeronautical experimentation significantly because it provided an effective method of controlling an airplane in three-dimensional space and, because it was aerodynamically based, it did not limit the size of the aircraft as shifting body weight obviously did. The satisfactory performance of the kite demonstrated the practicality of the wing warping control system. Encouraged by the success of their small wing warping kite, the brothers built and flew two full-size piloted gliders in and Beyond the issue of control, the Wrights had to grapple with developing an efficient airfoil shape and solving fundamental problems of structural design.
Like the kite, these gliders were biplanes. For control of climb and descent, the gliders had forward-mounted horizontal stabilizers. Neither craft had a tail.

The Wrights' home of Dayton, Ohio, did not offer suitable conditions for flying the gliders. An inquiry with the U. Weather Bureau identified Kitty Hawk, North Carolina, with its sandy, wide-open spaces and strong, steady winds as an optimal test site. In September , the Wrights made their first trip to the little fishing hamlet that they would make world famous. Although the control system worked well and the structural design of the craft was sound, the lift of the gliders was substantially less than the Wrights' earlier calculations had predicted.
They began to question seriously the aerodynamic data that they had used. Now at a critical juncture, Wilbur and Orville decided to conduct an extensive series of tests of wing shapes. They built a small wind tunnel in the fall of to gather a body of accurate aerodynamic data with which to design their next glider. The heart of the Wright wind tunnel was the ingeniously designed pair of test instruments that were mounted inside.

These measured coefficients of lift and drag on small model wing shapes, the terms in the equations for calculating lift and drag about which the brothers were in doubt. The Wrights' third glider, built in based on the wind tunnel experiments, was a dramatic success. The lift problems were solved, and with a few refinements to the control system the key one being a movable vertical tail , they were able to make numerous extended controlled glides.
They made between seven hundred and one thousand flights in The single best one was The brothers were now convinced that they stood at the threshold of realizing mechanical flight. During the spring and summer of they built their first powered airplane. Essentially a larger and sturdier version of the glider, the only fundamentally new component of the aircraft was the propulsion system. With the assistance of their bicycle shop mechanic, Charles Taylor, the Wrights built a small, twelve-horsepower gasoline engine.
While the engine was a significant enough achievement, the genuinely innovative feature of the propulsion system was the propellers. The brothers conceived the propellers as rotary wings, producing a horizontal thrust force aerodynamically. By turning an airfoil section on its side and spinning it to create an air flow over the surface, the Wrights reasoned that a horizontal "lift" force would be generated that would propel the airplane forward.
The concept was one of the most original and creative aspects of the Wrights' aeronautical work. The airplane was fitted with two propellers mounted behind the wings and connected to the engine, centrally located on the bottom wing, via a chain-and-sprocket transmission system.
By the fall of , the powered airplane was ready for trial. A number of problems with the engine transmission system delayed the first flight attempt until mid-December. After winning the toss of a coin to determine which brother would make the first try, Wilbur took the pilot's position and made an unsuccessful attempt on December 14th, damaging the Flyer slightly. Repairs were completed for a second attempt on December It was now Orville's turn.
At a. Three more flights were made that morning, the brothers alternating as pilot.

The second and third were in the range of two hundred feet. With Wilbur at the controls, the fourth and last flight covered With this final long, sustained effort, there was no question the Wrights had flown. As the brothers and the others present discussed the long flight, a gust of wind overturned the Wright Flyer and sent it tumbling across the sand.
