fter
the triumph of the first powered flights in 1903, 1904 was a trial. Even
before they began work, the brothers faced a tough decision. Flying, for them, had
grown to become more than an avocation.
They could not afford to devote the resources needed to continue their aeronautical experiments
without some sort of payback – their financial future was at stake.
Their bicycle business, which was already suffering from a
market-wide decline, had been shamefully neglected during 1902 and
1903 as they raced to get a powered airplane into the air. Could an
airplane business replace it?
On the long railroad journey back to Ohio from North Carolina, they
estimated what they had invested so far in research and development. All their aeronautical
experiments, including the materials needed to build their three
gliders and one Flyer, the four trips to and from Kitty Hawk, the
tents and sheds, even the wind tunnel had cost them a little
less than one thousand dollars That sounds absurdly inexpensive to
our twenty-first century ears, but it was the rough equivalent of
$60,000 to $70,000 US in today's currency – the research hadn't been
cheap. And still they didn't have a
marketable product. The Flyer had flown, but it was hardly a
practical flying machine. How much more time and money would it take
to develop their invention into a reliable form of transportation
that others would buy?
There was no clear answer. But, for the first time, they felt they
were at least within sight of a practical, salable airplane. They
had to try. So they let the bicycle business coast and concentrated
their efforts on developing their Flyer into a marketable product.
"We were compelled to regard it as a strict business
proposition," Wilbur later explained.
To take financial advantage of their work, they
would need a patent. They had already tried to file one themselves, but their application
had been rejected in 1903. So they decided to hire a professional patent attorney, Henry A. Toulmin, in nearby Springfield, Ohio. Toulmin advised them to continue work on a practical
flying machine, but to say as little as possible about their invention until the patent
was granted. In the meantime, he filed for a patent not just in the United
States, but many European countries as well.
To make real progress, the Wrights decided to bring their test flights closer to home.
During Orville's last years in school, the one subject he had loved above all others was
botany. It was taught by William Werthner, a noted scientist who had
pioneered the teaching of science in American high schools. Werthner loved
to get his students hands-on with science. He led his classes on field trips to
Huffman Prairie (between Dayton and
Springfield) to study the unique prairie environment. This was where, in the 1830s, botanist John Leonard Riddell had discovered three new
species of plants. Wilbur and Orville took another expedition out to the Prairie
to see if it might serve as a flying field.
At first glance, it seemed an unlikely choice. The Prairie was smaller than
the Wrights could have wished. It had poor drainage, making it wet and
marshy much of the year. And it was not flat. The area was covered
with small mounds, probably owing to the "hummock sedge" that
commonly grew in Ohio fens and bogs. In a letter, Wilbur described
making his way across the Prairie "jumping from hummock to hummock."
However, on closer inspection, Huffman Prairie had one important
characteristic that recommended it over many other Dayton-area
fields and pastures. The peat-like soil was soft and springy, not at
all like the unyielding clay typical of Ohio farms. The moisture in
the peat froze during the winter, making the soil expand – a
phenomenon known as a
"frost heave." This created tiny air pockets when the water melted in the
spring. The Wrights must have reasoned that the soft, heaved soil
could provide a measure of protection in the event of a hard landing
or a crash, as did the soft sands of Kitty Hawk.
Additionally, the Prairie was on the Interurban, the electric trolley line that
served the Dayton area – the Wrights could travel from West Third
Street to Simms Station, just across the road from Huffman Prairie,
in less than an hour. They asked permission from Torrence Huffman,
who owned an 84-acre tract of Huffman Prairie, to use it for their experiments. Huffman was bemused at their request,
but he saw no harm in letting them use this unproductive piece of land. His
only request was that they not harm the cows or horses that were
pastured there. (Privately, he
told Dave Beard, who lived on a farm next to Huffman Prairie, that he thought the Wright
brothers were "fools.")
The Wrights built a hangar in a corner of the Prairie, similar to their
hangar at Kitty Hawk and as remote as possible from the trolley stop.
They also built another airplane, the "Flyer II."
The 1904 Flyer II had a slightly flatter wing than the Flyer I, and its wing
ribs were much stronger and much simpler to construct. The skids were more
robust and held the propellers farther above the ground.. The Wrights also moved the pivot point of
the elevator so it wasn't so sensitive. But other than than, it was a clone
of the first Flyer. It even had a similar engine. Charlie
Taylor made two more horizontal four-cylinder engines with slightly larger
cylinders pistons and other improvements. One of these was used
for flying, replacing the engine that had been destroyed when a
gust of wind overturned the Flyer I. The second was a "bench engine." The
Wrights used it as a source of power for their experiments, especially their
experiments with propellers. They would also use it to test new ideas that
would help their engines develop more power or run cooler. If these ideas
worked, they transferred the improvements to their flying engine.
By May of 1904, the brothers were ready to resume
flying. They were beleaguered by another problem, however. Wild stories about their Kitty Hawk
flights circulated in the newspapers. (These had begun with a fantastic fabrication in the
Virginia-Pilot the day after the first flights -- "Flying Machine Soars 3
Miles in Teeth of High Wind...") The Wrights were genuinely amazed at the ease with
which the press manipulated the truth and were determined to correct the misconceptions
that abounded. They had issued a correction to the Associated Press on 5
January 1904, but the stories persisted – and grew in their audacity. In
February, without input or permission from either brother, The Independent magazine published a fictional account of
the first flights and signed Wilbur's name to it – The Experiments of a
Flying Man by Wilbur Wright. Hoping to set the record straight,
the brothers invited reporters from the prominent newspapers in Dayton and
Cincinnati to watch them fly their new machine with the understanding that there
would be no photographs allowed.
A crowd of about forty people gathered at Huffman Prairie on 23 May to watch
the Wright brothers fly. Although the Flyer I had
flown successfully just five months before, the Flyer II was reluctant to leave the
ground. The new engine was hard to start and continually misfired when the
brothers finally got it
going. Orville made a run down a 100-foot launching rail but never rose an inch off the
ground. They gathered the reporters again on 25 May, but a persistent rain
prevented them from attempting a launch. A very few reporters came out for a
third time on 26 May, but Orville managed only a brief hop of 25 feet.
Everyone went home disappointed – the reporters, the Wright brothers, even Bishop
Milton Wright wrote of the general discouragement in his diary. The Wrights hadn't shown
the world they could fly but, quite by accident, they had achieved one of their
objectives. The stories in the newspapers stopped. Based on what the
reporters had been
shown, they unanimously decided there was nothing to report. This was a bit
of good luck if only because it allowed the Wrights to work in relative
obscurity, undisturbed. Wilbur wrote to Octave Chanute, "The fact that we
are experimenting at Dayton is now public, but so far we have not been
disturbed by visitors. The newspapers are friendly and not disposed to
arouse prying curiosity in the community."
It was, perhaps, the only good luck they were to have for several months.
The remainder of the summer was a disappointing series of aborted launches
and crash-landings, often resulting in something breaking. Skids, spars,
rudder, elevator, and propellers snapped regularly. When the Flyer II
did fly, the flights were short and erratic with the Flyer "bobbing up and
down" or "undulating" throughout the brief time it was in the air. The
aircraft was unexpectedly unstable in pitch, with the nose always hunting up
or down. The Wright brothers mistakenly diagnosed the problem, deciding that
the Flyer II was balanced with its weight too far forward. They moved the engine and
radiator backwards, shortening the propeller shafts and supports to make the
airplane heavier in the tail. Resuming flight tests, the Wrights quickly
found that this only exacerbated the instability and they had to move
everything back. They even strapped iron weights to the skids just under the
elevator, moving the balance point forward from where it had been in May.
Still the Flyer undulated up and down. Wilbur wrote to Chanute, comparing
his and Orville's tribulations to those of the biblical prophet whom God had
jinxed: "We certainly have been "Jonahed" this year." Jonah aside, this
was the most difficult, the most crucial, and the most dangerous
juncture in the Wright brothers' quest to build a practical flying
machine. Will and Orv had returned from Kitty Hawk with less than
two minutes of experience between them piloting a powered airplane.
The Flyer II was unstable and unpredictable. Flying it would
have been a daunting task for an experienced test pilot, yet the
Wrights were learning to fly in this barely flyable aircraft.
That they did so is a testament to their ability to think through a
difficult problem, to manage enormous risk when testing a possible
solution, and to quickly learn the physical skills needed to operate
an ever-evolving machine. Because science advances through failure
as much as it does though success, the Wrights made progress in
spite of their alleged jinx. Little by little, their flights grew
longer; the crashes less severe. While the Flyer II remained
a cantankerous machine, their skill in handling it steadily
improved. On 13 August 1904, with their twenty-eighth test flight,
Wilbur managed to keep the airplane in the air for 1,304 feet (397
meters), surpassing for the first time his 852-foot flight on 17
December 1903 eight months previous. It was a short-lived victory,
however. On the same day, during the thirtieth flight of the season, Wilbur
crashed the Flyer II, breaking the elevator and a good deal
more. They crashed again three days later on 16 August. Eight days
after that, on 24 August, they up-ended the Flyer in a nose-first crash
leaving Orville "sore all over." In those eleven days, they had made
eleven flight attempts and only once had they exceeded that elusive
852-foot mark ― on August 22, their thirty-third flight had spanned
1,432 feet (436 meters). Most flights were under 200 feet (61
meters). Clearly sharpening their take-off skills would only carry them
so far. To make real progress, something more was needed.

A map of the Huffman Prairie Flying Field at the junction
of Dayton-Springfield Pike and Yellow Springs Road. This was sketched by
Orville years after the flying experiments of 1904 and 1905.
Huffman Prairie was covered with small mounds or hummocks. This was
probably due to "hummock sedge," a type or prairie grass of found in
Ohio fens and bogs.
Today,
Huffman Prairie is part of Wright-Patterson Air Force Base. To visit

Just a few years prior to 1904, the Dayton, Springfield and Urbana
Electric Railway had built a spur line that stopped at Simms Station,
just opposite Huffman Prairie.
Wilbur and Orville talk in front of the Flyer II. Part of the wing is
still inserted in the shed they built to serve as a hangar. The Flyer
sat lengthwise in its hangar; Orville and Wilbur had to remove the front
elevator and the rear rudder to put the Flyer away.
The Wright Flyer II poised on its launching rail with the hangar/shed
behind it.
The 1904 Flyer II (bottom) was a virtual clone of the
1903 Flyer I (top). Because the Wrights made only four flights in their first aircraft before a gust of wind rolled it
over, they felt they had not adequately tested the design. So except for
some minor changes, the first two Wright Flyers were
identical.
Wilbur and Orville lay track -- the track had to be laid parallel to the
wind before each flight. Hoping to achieve the necessary speed for a successful
take-off, the Wrights often laid over 250 feet (76 meters) of track.
Initially, the Wrights could not get off the ground at Huffman Prairie,
but by mid-summer they were making short flights just a few feet off the
ground. This was their 19th
attempt to fly on 5 August 1904.
The Wrights didn't equal or surpass the distance they had flown at Kitty
Hawk in 1903 until 13 August 1904. This is a flight that Orville made
that day immediately after Wilbur flew 1,304 feet (397 meters).
Many of the early flights at Huffman Prairie ended
like this one on 24 August 1904, with the Flyer II crashed just a few hundred feet from the end
of the track. Note the "ski-jump" at the end of the rail to help get the
Flyer airborne. |
