Qrville
and Wilbur Wright – were the young operators of a modest neighbourhood bi-cycle
shop at 11/27 West Third Street in Dayton. After years of experience with aeroplane models in a wind tunnel, the Wright brothers had established firm principles of design and then built their first powered aeroplane capable
of carrying one of them. Their little craft, the Kitty Hawk Flyer, had a wingspan of just over 40 feet and weighed only 605 pounds.
It
was powered by a frail four-cylinder engine that developed 12 h.p. at full throttle. After several unsuccessful
tries from the lower slope of Kill Devil
Hill on December 14, the brothers moved to the largest of the nearby sand dunes
at Kitty Hawk. In true pioneering spirit, the Wright brothers were ready to try
again. The date: Thursday, December 17, 1903.
A cold and biting wind coming off the Atlantic Ocean did not provide ideal flying weather, but the Wrights elected to risk another attempt anyway.
A small, wooden launch track was laid on the level sand about 100 feet west of the primitive building which served the Wrights as living quarters and hangar. They knew that the high wind gusting up to 30 m.p.h., would add to the difficulty of controlling the 15 flimsy aircraft but they also knew that it would provide added lift at take-off and would also reduce the landing speed.
It
was Orville’s turn to fly. The engine was started and warmed up. Orville settled himself in a prone position, with his hips resting in the
saddle and his feet braced against a footrest. His left hand grasped the
elevating lever. His right arm supported his weight. His right hand was ready
to shut off an engine speed to a stop-watch, and a wind speed meter as soon as
the flight ended. With the propellers rotating at full r.p.m., the restraining
wire was released.
The craft moved forward slowly. Running alongside the right wingtip, Wilbur was
able to keep up with it. It ran 40 feet along the launch track, gradually
building up speed, and then, suddenly, the Kitty Hawk Flyer was air-borne,
winging into history. Orville later recounted modestly what man’s first
airplane flight was like: ‘The course of the flight up and down was
exceedingly erratic, partly due to the irregularity of the air and partly of lack of experience in handling this machine.
The control of the front rudder was difficult on account of its being balanced
too near the center. This gave a tendency to turn itself when started so that
it turned too far on one side and then too far on the other. It, the machine
would rise suddenly to about ten feet, and then as for the ground. A sudden
dart when a little over 100 feet from the track, a little over 120 feet from the
point at which it rose.
Three
more flights were made on the same day. The longest, by Wilbur, covered 852 feet
in 59 seconds. Unfortunately, while the Wrights and the five witnesses present
were discussing their success, a sudden and violent gust of wind upended the
machine and damaged it severely.
The
Wright brothers continued to develop their unique invention but it was some
time before people were willing to believe that a flying machine actually
existed.
