The names of the places where Wilbur and
Orville Wright made history are familiar to people everywhere who know
and cherish the story of the invention of the airplane. The brothers
tested their first kite/glider at Kitty Hawk, North Carolina in 1900,
then shifted their seasonal camp four miles south to the Kill Devil
Hills, where they flew from 1901 to 1903. They perfected their invention
at Huffman Prairie, eight miles east of Dayton, in 1904 and 1905, and
opened their flying field there in 1910.
Wilbur astonished the world with his first public flights from the
racecourse at Hunaudieres, France, in the high summer of 1908, while
Orville demonstrated the airplane at the Army trials at Ft. Myer,
Virginia in 1908 and 1909. Wilbur taught the first three U.S. Army
airmen to fly in 1909 at College Park, Maryland. And there are other
familiar places, from Governor's Island in New York harbor, where Wilbur
took off for his flight around the Statue of Liberty in 1909, to a field
near Montgomery, Alabama, where Orville made the first night flights,
and began to instruct the young men who would fly as members of the
Wright exhibition team.
Ironically, the precise spot where Wilbur tested their first
experimental aircraft is unknown to all but the most knowledgeable
students of Wright lore. Many of the circumstances surrounding that
first Wright flight test remain hazy. The date of the test, even the
month, is uncertain. A century after the Wright brothers began their
period of active experimentation with the flights of their wing-warping
kite of 1899, the time has come to clarify the record in so far as that
is possible. How had it begun?
"My brother and I became interested in the problem of flight in
1899," Wilbur Wright explained in February 1912. When queried about the
precise date when they had "conceived the invention ...[covered in their
patent]," Wilbur replied that: "The general idea, which forms the basis
of the patent, was conceived about the latter part of June 1899." His
brother Orville differed only slightly, noting that the moment of
insight had occurred "in the early part of June 1899." Clearly, the late
spring and early summer of 1899, when the Wright brothers took their
first active steps toward the invention of the airplane, was a critical
moment in their story. The spark of interest had begun to smolder three
years before, however, when, as Wilbur noted, "...the death of Lilienthal
... brought the subject to our attention and led us to make some inquiry
for books relating to flight."
"But the only serious books we found were by Prof. [Etienne Jules]
Marey and these related to the mechanism of bird-flight rather than
human flight. As our interest at that time was mere curiosity as to what
had been done, we did not pursue the subject further when we failed to
find books relating to human flight." [1] Orville Wright recalled that there had been a
great deal more to it than that. "From the date of the death of
Lilienthal in [August 10] 1896," he remarked, "we were so interested [in
aeronautics] that we discussed matters in this line almost daily."[2]
Their interest, Orville noted, was "...again aroused [in 1899] as a
result of the reading of a book on ornithology." [3] Wilbur explained that it was "...while
reading a book on Ornithology that we became interested in studying the
appearance and habits of birds, but it soon occurred to us that the
really interesting thing about birds was their power of flight." [4]
"Our own growing belief that men might nevertheless learn to fly was
based on the idea that while thousands of creatures of the most
dissimilar bodily structures, such as insects, fishes, reptiles, birds
and mammals, were every day flying through the air at pleasure, it was
reasonable to suppose that men might also fly. Of course, there might
be, and doubtless would be, many serious difficulties to be overcome,
but we thought that by learning what these difficulties were and finding
methods of overcoming them, the problems of human flight might be
solved, and we thought that probably the cheapest and best way to take
up the subject would be to acquaint ourselves with the troubles which
others had met in attempting to solve the problem."
The first direct evidence of their serious interest in aeronautics
came on May 30, 1899, when Wilbur Wright wrote what is perhaps the most
important letter ever received by the Smithsonian Institution. "I am an
enthusiast," he explained, "but not a crank in the sense that I have
some pet theories as to the proper construction of a flying machine."
Noting that he was "...about to begin a systematic study of the subject in
preparation for practical work to which I expect to devote what time I
can spare from my regular business," he requested "such papers as the
Smithsonian Institution has published on this subject, and if possible a
list of other works in print in the English language." [5]
Assistant Secretary of the Smithsonian Richard Rathbun replied just
three days later. It was a testament both to the speed of the U.S.
Postal Service in the closing years of the old century, and to the
Smithsonian's emphasis on rapid response to public inquiries, even by
officials at the highest levels of the Institution. Moreover, the
response was full and satisfying. Rathbun provided the Wrights with free
copies of four Smithsonian reprints: translated extracts from Louis
Mouillard's Empire of the Air; Otto Lilienthal, The Problem of
Flying and Practical Experiments in Soaring; Samuel P. Langley,
The Story of Experiments in Mechanical Flight; and E.C. Huffaker,
On Soaring Flight. He also included a list of recommended
publications on the subject, including S.P. Langley, Experiments in
Aerodynamics; Octave Chanute's Progress in Flying Machines;
and the 1895, 1896, and 1897 issues of The Aeronautical Annual.
Wilbur immediately replied, thanking Rathbun for the pamphlets and
enclosing a dollar for the Langley volume. An entry for the second week
in June 1899, in the ledger in which the Wrights kept a meticulous
account of the receipts and expenditures of the bicycle shop includes an
expenditure of $5.50 "for books on flying." In addition to ordering the
Langley book, the brothers must have taken Rathbun's advice and
purchased the Chanute volume and the available issues of the
Aeronautical Annual, as well. [6]
The spring of 1899 had been a busy time for the residents of No. 7
Hawthorne Street, Dayton, Ohio. The pater familias, seventy-one year old
Bishop Milton Wright, as usual, spent a great deal of time on the road,
visiting far flung congregations, calling on relatives in Ohio and
Indiana, and attending church conferences. When at home, he made
periodic visits to the dentist who was fitting him with a "vulcanized"
upper plate; supervised the workmen who were refurbishing the kitchen
and the "east room" of the house; and handled family business, including
the sale of timber on an Indiana farm.
But there was always time for his grandchildren, especially his son
Lorin's eldest boy and girl, Milton and Ivonette, who lived just around
the corner on Horace Street. At young Milton's request, he took them on
walks to their grandmother's grave in lovely Woodland Cemetery. On May
10, 1899, the three of them cheered from the upper story windows of a
church office as Col. William F. "Buffalo Bill" Cody paraded his Wild
West Show through the streets of Dayton. Grandfather and grandchildren
alike were looking forward to fireworks on the Fourth of July.
It was a busy spring for twenty-four year old Katharine
Wright, as well. Katie, as her father and friends knew her, was the only
college graduate in the family, Oberlin, Class of '98. Recently
"elected" a teacher of English and Latin on the regular faculty of
Central High School, she spent the spring and summer preparing for and
enjoying her high school reunion, and entertaining visiting college
friends. She and a group of friends hosted a supper for a visiting
Oberlin Professor on May 20. A college chum, Margaret "Mag" Goodwin,
arrived for a visit after June 8. The two of them took a train for
Oberlin, and their first college reunion, on June 15.
Orville would later recall that serious discussions of aeronautical
issues were well underway "while Miss Goodwin ... was visiting in our
home." [7] The first step
was to assess the state of the aeronautical arts. "As to the state of
the experimental knowledge at the time we began our experiments," Wilbur
explained:
"...we reached the conclusion that the problem of constructing wings
sufficiently strong to carry the weight of the machine itself, along
with that of the motor and of the aviator and also of constructing
sufficiently light motors were sufficiently worked out to present no
serious difficulty; but that the problem of equilibrium had been the
real stumbling block in all serious attempts to solve the problem of
human flight, and that this problem of equilibrium in reality
constituted the problem of flight itself." [8]
From the outset, as Wilbur explained, "we were actively studying the
means of controlling [an] aerial apparatus in the air...." [9] They immediately
recognized that the real problem related to control in the roll axis,
raising or lowering either wingtip at will to maintain balance in the
air. "[We] ...conceived the idea of adjusting right and left wings to
respective different angles of incidence," Wilbur explained, "for the
purpose of controlling lateral balance." [10]
How was that to be achieved? Orville suggested "...mounting the wings ...
upon axles extending laterally from the center of the machine with gears
attached to the two wings meshing so that when the lever attached to
either wing was pushed forward or backward the wings would face forward
at different angles to each other." [11] Wilbur, however, argued that the scheme was
impractical because of the weight of such a mechanism and the difficulty
of incorporating it into an adequate structure.
Harriet Silliman, another one of Katharine's college friends, arrived
for a visit on Thursday, July 20. [12] Wilbur was working late in the bicycle shop a day or
so later, while Orville and Katie were off somewhere entertaining Miss
Silliman.
"One evening while studying the movements of a little square paper
tube which I was using for the purpose of noting the movements of one
side which I conceived to represent the upper plane of a double deck
structure and the opposite side which I conceived to represent the lower
plane, I noticed that the upper plane could be moved bodily forward or
backward with reference to the lower plane which would be useful in
controlling the fore and aft equilibrium of the apparatus, or if the top
plane were moved forward at one end and backward at the other the whole
structure would be twisted so that the right ends of the plane would be
pulled down at the rear while the left ends would be elevated. Thus each
plane would assume a screw form or helicoid and the right wing would
have a greater angle than the left wing." [13]
When Orville returned home with the ladies later that evening, Wilbur
was waiting with the box. "By marking vertical and diagonal lines on the
...two vertical walls...[Wilbur] represented the upright posts and the
diagonal truss wires of a superposed aeroplane." [14] Wilbur carefully positioned his index
fingers and thumbs on either end of the box and twisted. Orville
recalled that they became "... very enthusiastic...." [15]
Wilbur then proceeded to build "...a little model made out of bamboo
having lateral spars and upright standards connecting them, the whole
being braced by truss threads." [16] It was an even clearer demonstration of the warping
principle, and indicated a means of incorporating the technique into an
actual structure.
His next step was to design, build and test their first real
aircraft, a kite that would enable them to test their control system in
the air. "The kite had two slightly curved planes," Wilbur explained,
"about thirteen inches from front to rear, and about five feet from tip
to tip, one being placed above the other and connected to it by two rows
of upright standards, one near the front edge and the other row near the
back edge." Wilbur attached the upright struts to the wings with
flexible connections, "...so that the top plane could be thrown forward or
backward with reference to the lower plane." [17]
A single rod attached to the mid-point of the middle rear strut
supported a rectangular, horizontal elevator. When the top surface of
the kite moved forward or backward, the trailing edge of the elevator
rose or fell to assist the kite in climbing or diving.
Orville remembered that the kite surfaces were braced across the
front and back with light wires forming a Pratt Truss, a classic
American bridge truss. This would allow the top surface to move to the
front or rear of the lower wing, causing the kite to climb or dive. The
wings could also be twisted for lateral control, like the box and the
bamboo model, but could not move to the right or left in parallel with
one another. Lines connected to the top and bottom of the outside front
struts on both the right and left sides led to wooden sticks held by the
operator.
The lines on the right and left were crossed, so that the operator
could tip the top of the two sticks in his hand forward to allow the top
wing to move back causing the kite to climb. Pointing the top of both
sticks to the rear would cause a dive, and pointing the top of one stick
forward and the other to the rear would cause the kite to bank in one
direction or the other. It would be the first flying machine of any kind
capable of maneuvering while operating completely under the control of
the pilot.
The structure of the kite was built entirely of pine. The wings were
covered with fabric and sealed with shellac. [18] An examination of the ledger book in
which the Wrights recorded all of their income and expenditures reveals
a number of interesting purchases that might have been related to the
kite, including several entries for ten cents worth of muslin, and
Wilbur's purchase of a ten cent ball of string in the last week in July,
or the first in August. In any case, the book records that Wilbur
reported a great many unspecified expenditures during late July, any of
which might have been related to the kite. [19]
Wilbur later recalled that he was at work on the kite "within a few
days" of having experimented with the cardboard box and the bamboo
structure. "The actual work on the kite was done mostly by myself,"
although "...it embodied the results of numerous conversations between
us." [20] While Orville
was helping Katharine entertain their guest, Wilbur spent long hours at
the bicycle shop, waiting on customers, performing repairs, and
constructing his kite. "I was not able to be present when the structure
was flown as a kite, but I operated the machine in ... our store before it
was taken out to be flown," Orville recalled. "My brother held the kite
in his hands while I warped the wings by means of the four cords."
Katharine, Harriet, Orville and a group of other friends left for a
camping trip at a spot near Dayton's Fairview Park during the first week
in August 1899. The party returned home on August 7, the first Monday of
the month. [21] The
tests of the kite, Wilbur recalled, were made before the trip. Orville
agreed with his brother, recalling that he had returned from the camping
trip on Tuesday August 8, and that Wilbur had visited him in camp on
Sunday, August 6, at which point they discussed the kite tests that had
been conducted prior to his departure. In the late summer of 1899 the
Wrights did not have an assistant who could man the bicycle shop in
their absence. Presumably, Orville did not witness the kite tests
because he had to mind the store. [22]
Wilbur reported that he flew the kite "a number of times about the
end of July." [23] He
had given the question of where to fly it considerable thought, and
selected an open area on the grounds of the Union Theological Seminary,
at the corner of West First Street and Euclid Avenue in Dayton, Ohio.
"This field is now part of the city," Wilbur explained in a deposition
offered just a month before his death. "But at that time [it was] a
retired place where I thought no one would intrude." [24]
Officials of the Church of the United Brethren in Christ opened the
doors of the impressive three-story structure in 1878. Since that time,
it had become a landmark on the western edge of Dayton. Eight years
before, Katharine, then a high school student, had mentioned the place
in an essay describing the sites encountered by passengers on a horse
car traveling east along West Third Street. Having begun the journey at
the Third Street car barns, and passed the already historic Miami City
school, the tour guide directed the attention of her readers to the next
noteworthy site along the route.
"To the left, about two squares distant, is another school, sometimes
irreverently called "the preacher factory." Its official name is Union
Biblical Seminary. It stands in the center of a beautiful campus on high
ground overlooking the valley of Wolf Creek, and is the first building
to attract the eye of travelers entering the city by railroad from the
west." [25]
Wilbur remarked that he had flown the kite more than once. The fact
that the drawings of the kite which he prepared for use during a
deposition on the morning of March 30, 1912, show a short section of
pipe tied to the center forward strut certainly indicates that he had
flown it enough to realize that it was tail heavy.
In spite of Wilbur's desire for privacy, there were witnesses to the
tests. Fred Fansher recalled that he had been flying kites with ten or
twelve other boys in an empty lot adjacent to the Seminary at the corner
of Summit and West First, when Wilbur Wright walked by carrying "...what
looked to us like a peculiar sort of box kite." Curious, the boys
pulled their own kites down and followed Wilbur onto the Seminary
grounds. [26]
John Myers remembered that Wilbur had asked him to hold the kite as
far above his head as he could and to let it go when instructed. "There
was quite a big wind that day," he noted. "I recall that when he tilted
the planes the kite came down very rapidly, darted in other words.... He
made several attempts and them boxed it up and put it away." [27]
John Reiniger had been there, as well. "At times it would have a
tendency to come down," he recalled, "which would be overcome by the
manipulation of the sticks in Mr. Wright's hands." Once, he remembered,
the kite had gotten completely out of control and swooped down to the
ground. [28]
Of course, Wilbur gave Orville a detailed account of the tests.
Several days later, John Reiniger and his brother Walter stopped by the
bike shop and provided what we can safely assume to have been a spirited
description of the proceedings. "According to Wilbur's account of the
tests," Orville remarked, "the model worked very successfully."
"It responded promptly to the warping of the surfaces, always lifting
the wing that had the larger angle [of incidence]. Several times,
according to Wilbur's account to me, when he shifted the upper surface
backward by the manipulation of the sticks attached to flying cords, the
nose of the machine turned downward as was intended; but in diving
downward it created a slack in the flying cords, so that he was not able
to control it further. The model made such a rapid dive to the ground
that the small boys present fell on their faces to avoid being hit, not
having time to run." [29]
During the course of a series of patent suits that began in 1909 and
ran for over two decades, the origins and operation of the 1899 kite
would repeatedly become a matter of some legal importance. It was, after
all, the starting point of the Wright experiments. As a result, the
brothers were forced to reconstruct events that had occurred more than a
decade before, which seemed much more important in hindsight than they
had at the time. In general, their method of dating the small steps
leading to the kite tests involved remembering the comings and goings of
guests, the camping trip and other household events occurring at the
same time.
There is one puzzling anomaly, however. The brothers relied on their
father's meticulous diary to establish a basic timeline of events in the
Wright household during the spring and summer of 1899. In his entry for
July 7, Bishop Wright reports that his grandson Milton visited that
evening, "to see the flying machine." [30] According to the chronology reconstructed by the
brothers, however, there was no "flying machine" in early July. The
incident with the paper box, which set everything in motion, did not
occur until on or about July 20. Perhaps young Milton came to look at
pictures of flying machines in the books and pamphlets that his uncles
had recently acquired.
In addition to reconstructing the weeks when they had taken their
first steps toward the invention of the airplane, the Wrights had to
locate witnesses who could testify to having seen the kite maneuvering
in the air. Some of the boys were easy enough to find. John Reiniger
was still living in Dayton, as were Fred Fansher, who was serving as
Secretary of the Chamber of Commerce in 1912, and John Myers, who had
become an electrician. The Wrights wrote letters to other men, now
living as close as Cincinnati and as far away as Georgetown, Texas, whom
they thought might have been among the ten or a dozen youngsters who had
seen the kite fly thirteen years before. [31] Apparently, there were no
responses.
Opposing counsel in the various patent suits would also express
curiosity with regard to the ultimate fate of the objects that had
played such an important role in the initial involvement of the Wright
brothers in aviation. "I do not think that we have parts of any of our
kites or gliders before the motor aeroplanes [sic] of 1903," Wilbur
explained. [32] While he
did not actually remember, he presumed that the little bamboo model had
been "thrown in the waste basket or wood box." [33]
"The kite remained about the store for three or four years," Wilbur
recalled, "and was used at various times in making experiments with an
automatic stabilizer." During one of those tests, probably in 1905, "...it
was so badly broken that no attempt was made to rebuild it." [34] The 1899 kite had
outlived its historic progeny, the 1900, 1901 and 1902 Wright gliders.
Like them, however, it ultimately found its way into "the waste basket
or wood box."
"Following these flights [of the 1899 kite]," Wilbur recalled, "we
decided to build a much larger kite sufficient to support a man, and we
made a search for grounds in the vicinity of Dayton but found nothing
that suited us." [35]
This time they would have to look a bit farther afield than the Union
Theological Seminary. Just a year later, on Thursday, September 6, 1900,
Wilbur Wright boarded a Big Four train at Dayton's Union Station. He
was bound for Elizabeth City, North Carolina, where he would hire a boat
to carry him across Albermarle Sound to the little village of Kitty
Hawk, on the Outer Banks of North Carolina. Safely packed away in the
baggage car were the prefabricated makings of the 1900 kite/glider, the
first full-scale Wright airplane. The freight charge was $2.53, several
times the cost of the small kite that had started it all. [36]
