Aeronautics -- United States -- Biography; Wright, Orville, 1871-1948; Wright, Wilbur, 1867-1912
Toward the end of September, the Wrights were able greatly to increase
their distances. On September 26, there was an uninterrupted flight of
11⅛ miles in 18 minutes and 9 seconds; and on September 29, one of 12
miles in 19 minutes 55 seconds. Then, on October 3, there was a new
record of 15¼ miles in 25 minutes 5 seconds; another, on October 4,
of 20¾ miles in 33 minutes 17 seconds; and finally, on October 5, 24⅕
miles in 38 minutes 3 seconds.
The flights of October 3 and 4 would have been longer except that
certain bearings had become overheated. By October 5 the inventors had
added more grease cups where needed and also installed a larger gas
tank. But the tank was not full when that final test began and the
flight ended because the fuel was exhausted. It was the intention of
the Wrights to make one more test and put the record at more than an
hour; but now for the first time the miracle of flight actually began
to attract more spectators and the brothers decided it might be prudent
to quit for the season before details of the machine’s construction
became public knowledge. However, there was one more short flight--just
one circle of the field--on October 16.
After the close of the 1905 experiments, a test of the engine showed
that it produced more power than when first put into use. This gain
was attributed to the increased smoothness of the cylinders and pistons
produced by wear.
Looking back over their experiments, the Wrights noted that “in 1903,
62 pounds per horsepower were carried at a speed of 30 miles an hour;
in 1904, 53 pounds at 34 miles an hour; and in 1905, 46 pounds at 38
miles an hour.” Thus the weight carried per horsepower was in inverse
ratio to the speed--the smaller the weight carried per horsepower, the
higher the speed. That seems obvious enough now, but at the time the
Wrights were making these experiments many scientists still accepted
the “Langley Law,” that the greater the speed, the less horsepower
necessary.
The Wrights now knew that the airplane would have practical use--though
they did not foresee how safely trans-Atlantic flights would be
made--and not even in their wildest dreams did they think of anyone
ever flying at night.

IT STILL WASN’T “NEWS”
Though Dayton newspapermen had not besieged the Huffman pasture for
details of the great news story lurking there during 1904-’05, one of
their number had occasionally been in contact with the Wrights. That
was Luther Beard--no kin to the other Beards mentioned--managing editor
of the Dayton _Journal_. Besides being a newspaper editor, Beard also
taught school at Fairfield, about two miles from the Huffman farm, and
went back and forth by the interurban car line that passed the field
where the Wrights were making history. It sometimes happened that on
the trip to Dayton he was on the same car with one or both of the
Wright brothers, returning from their flights.
