Aeronautics -- United States -- Biography; Wright, Orville, 1871-1948; Wright, Wilbur, 1867-1912
With all the knowledge and skill acquired in thousands
of flights in the last ten years, I would hardly think
today of making my first flight on a strange machine in a
twenty-seven-mile wind, even if I knew that the machine
had already been flown and was safe. After these years
of experience, I look with amazement upon our audacity in
attempting flights with a new and untried machine under such
circumstances. Yet faith in our calculations and the design
of the first machine, based upon our tables of air pressures,
obtained by months of careful laboratory work, and confidence
in our system of control developed by three years of actual
experiences in balancing gliders in the air, had convinced us
that the machine was capable of lifting and maintaining itself
in the air, and that, with a little practice, it could be
safely flown.
Wilbur having used his turn in the unsuccessful attempt on the
14th, the right to the first trial now belonged to me. After
running the motor a few minutes to heat it up, I released
the wire that held the machine to the track, and the machine
started forward into the wind. Wilbur ran at the side of the
machine, holding the wing to balance it on the track. Unlike
the start on the 14th, made in a calm, the machine, facing a
27-mile wind, started very slowly. Wilbur was able to stay with
it till it lifted from the track after a forty-foot run. One of
the Life Saving men snapped the camera for us, taking a picture
just as the machine had reached the end of the track and had
risen to a height of about two feet.[4] The slow forward speed
of the machine over the ground is clearly shown in the picture
by Wilbur’s attitude. He stayed along beside the machine
without any effort.
The course of the flight up and down was exceedingly erratic,
partly due to the irregularity of the air and partly to 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 it a tendency to turn itself when
started, so that it turned too far on one side and then too
far on the other. As a result, the machine would rise suddenly
to about ten feet, and then as suddenly dart for the ground. A
sudden dart when a little over a hundred feet from the end of
the track, or a little over 120 feet from the point at which
it rose into the air, ended the flight. As the velocity of the
wind was over 35 feet per second and the speed of the machine
over the ground against this wind ten feet per second, the
speed of the machine relative to the air was over 45 feet per
second, and the length of the flight was equivalent to a flight
of 540 feet made in calm air.
