AERONAUTIC CONCOURSE
A seven-acre dirt field and hanger  made up the
Aeronautic Concourse. The area was  was surrounded by
a 6,559 dollar  30-foot high fence (in order to redirect
wind). The crudely  made buildings included a large
aerodrome that cost 13,888 dollars; also called the 
balloon house, it was used to  inflating balloons from
the two concourse's gas plants which cost 16,052 dollars.

Gliders, kites, captive balloons, and motorized balloons
were also flown.

While the Wright brothers flew their historic 12 second
self-propelled flight  in December of 1903,  the Fair 
became a platform for flight development.

The US government posted a 100,000 dollar prize during
the Fair, who could build a one-seater self-propelled flying
machine.  Further rules  demanded that the fliers needed
to maintain a flight speed of at least 20 miles an hour and return from a triangular one mile  designed course. If accomplished before July 1, 1904, there would be an added 10,000 dollar bonus.

Crude  airplanes and dirigibles were used during the June first through September 30th contest, but not one person won the award. Still progress in development was made.






















Most airships and dirigibles had problems controlling direction.

Aeronauts such as E. C. Benbow from Butte, Montana  and Hyppolyte Francois of France, were unsuccessful on the prescribed course. San Franciscan  dirigible designer- Captain  J. S. Ballwin's `Californian Arrow,'  made a successful flight, under the piloting of N. Roy Knabenshue,  but did not achieve it on the prescribed course as well as within the contest's time frame.

The French airship-  Ville de Saint Mande

William Avery, one of aviation pioneer Octave Chanute's proteges, made glider demonstration flights.

A hot air balloon race was held on August 27, on Liberal Arts Day.  Famous airship makers such as George Tomlinson of Syracuse NY, and Carl E. Myers of Frankfurt, NY. took off, but failed to get close to the winning condition (flying within 200 miles of the Washington Monument in Washington DC).  An ill wind blew their airships in the opposite direction of their destination. Neither flew further than 500 miles. No one won the 5,000 dollar prize.  In fact only 1,000 dollars were given away in competition prize money.

FAIR  SABOTAGE!

Fair officials and the public looked  to Alberto Santos-Dumont  as a hopeful in  winning  the  100,000  dollar  prize. His  airship `Number 7,'  built for the Louisiana  Purchase Exposition  in  1903   was 164 feet long, 26 1/4 feet in diameter, and had a capacity of 44,500 cubic feet of hydrogen. It was powered by a sixty-horsepower Clement engine, driving two 16 1/2 -foot propellers

On May 16, 1904, Santos-Dumont  wired Fair  officials  informing them  that he: "Lost sixty horse power engine. Only able to get forty. Airship tried yesterday. Only goes less than twenty miles (per hour). Cannot race until speed condition is cut down to fifteen miles per hour."

Fair  Transportation chief-  Willard Smith told   Santos-Dumont  that  they  would change  the  rules. In fact,  there was a 50,000 dollar prize   if a speed of fifteen miles an hour is attained; 75,000  dollars if  eighteen mph  was obtained; 100,000  dollars if he  went  twenty miles mph. The fifteen-mile prize will be 69,000 dollars, if the flight is effected in June.

The management of the Fair offered a 10,000  dollar  bonus  if any contestant performed a successful flight at either of these three speeds before July 1. Unless a minimum of fifteen miles per hour were attained, however, no prize would be awarded at any time.

Santos-Dumont's plane  arrived by train  from New York on June 26 in three large eighteen foot cases, each    weighing two tons.

Without the  superintendent of aeronautics' approval, Santos-Dumont left the cover off the crate in the  evening to let the air circulate around the envelope.

At 7:00 a.m. the next day, June 28, one of the French mechanics discovered four, yard-long slashes in the gas bag obviously  from a  knife.  Nightwatch man  J.H. Peterson had been on duty from dusk until midnight, when he was relieved by Lucian T. Gilliam. Gilliam stated that  he had been absent twice during the night for short periods for cups of coffee.

The Exposition Company offered a 1,000 dollar  reward for the culprit.

Santos-Dumont  left for Paris July 1 without cooperating with the police or pressing the investigation. He had told exposition officials that he would repair his ship and return by September, but on July 14, 1904, he  knew it  work  take at least two months to repair the damage on Number 7, at a  cost of 8,000 dollars.






























Some felt the arson  was the work of a vandal or a jealous rival, while  the Esposition's Jefferson Guards thought that  Santos-Dumont himself had slashed the envelope because he feared that he would fail in the severe trials and wished to save face.

Inflating a blimp  at the  Fair.
The Wright brothers  did not participate at the St. Louis Fair. After  touring the                                  siteearlier that year, they concluded that the  grand prize contest was unachievable.
On October 19, the Fair help a kite flying contest open to adults as well as children.

On October 25, the Californian Arrow made a 20 mile flight, that lasted 37 minutes at an altitude of 2,000 feet. The air ship left the fairgrounds and landed safely in East St. Louis.  Knabenshuee later became America's first dirigible pilot, and went on to build the first passenger dirigible in the U.S.

The California Arrow held 7,500 to 8,000 cubic feet of gas.
