far as is known, the first man-carrying, heavier-than-air craft—the
first airplane—flew not at Kitty Hawk, North Carolina in 1903, nor
Texas the year before. Nor did it fly in California in the 1880s,
though apparently a steam-powered monoplane was flown there then.
It flew in Gillespie
County, Texas—in 1866.
Enter Jacob Brodbeck—genius.
Jake Brodbeck was an inventor. His wife had a powered washing machine
in the 1860s, using a power takeoff from the windmill. Jake designed
the power takeoff. He also built rubber-band powered flying toys for
children. Somehow, for some reason, Jake got the idea that he should
build a machine that could not only fly, but could carry a man as
The idea was probably economic. The Fredericksburg
to San Antonio stagecoach
was the most often robbed stagecoach in Texas.
was one of the few counties in the state that voted against secession
in 1861, and—during reconstruction—one of the few counties that prospered.
However, there were no banks
The closest banks were in San
Antonio. If people in Fredericksburg
wanted to put money in the bank, they had to send the money to San
Antonio. The only ways to get it to San
Antonio were to carry it one’s self or send it by stagecoach.
Either way, the money was apt to be stolen. The robbery of the Fredericksburg
to San Antonio stage
was so common that it even found its way into fiction. O. Henry wrote
a story about the robbery of the Fredericksburg
to San Antonio stage.
But suppose a man could carry money to San
Antonio from Fredericksburg
five or six hundred feet in the air, moving along at forty or fifty
miles per hour? That would make robbing the courier awfully difficult.
It could also be very profitable for the person who could carry the
money. His neighbors would probably pay handsomely to have their money
delivered to San Antonio’s banks without the risk of being stolen.
That’s likely the reason Jake Brodbeck started, in the early 1860s,
to work out a way to fly.
flying machine—nobody called it an ‘airplane,’ not even an ‘aeroplane,’
the earlier form of the word—is believed to have had a boat-like,
open top fuselage and wide, bird-like wings. One thing it did have
was what is known as a ‘forward canard’—a stabilizer forward of the
nose to prevent stalling. It needed the forward canard.
Jake didn’t have an engine. The internal combustion engine was somewhere
in the future in the 1860s, and he didn’t have the materials or expertise
to build a lightweight steam engine like the one that powered Langley’s
‘aerodrome’ or is rumored to have powered the California monoplane
that took to the air years later. What he had was a large, powerful
clockwork motor and a series of gears. This motor didn’t develop enough
power for the machine to take off on its own. Jake built a ski-jump
like ramp on the side of a hill near Fredericksburg.
The machine was taken to the top of the ramp, then, as it gained speed
sliding down the ramp, Jake would engage the motor. The machine would
nose up coming off the ramp—a condition that would certainly have
led to a stall, considering the very slow speed of the machine. That
is, it would have stalled without a forward canard. Probably it did
stall, which was why Jake added the forward canard.
Jake could jump his machine off its ramp and fly for three or four
minutes under power, then glide to a landing. The machine would fly—but,
unless he could devise a more lasting source of power, it was an interesting
toy, nothing more.
Jake sold stock in his machine, and at the same time began to work
out a way to increase the endurance. He would have to have probably
an hour and a half to two hours of continuous power to fly all the
way to San Antonio.
hit upon an idea. Unfortunately, it was one of those ideas that work
perfectly on paper but, in the real world, don’t work at all. Jake
designed two interdependent clockwork motors, one to rewind the other.
When Motor A became unwound, Motor B would be engaged to rewind it.
As soon as Motor A was rewound by Motor B, the pilot—Jake—would manually
rewind Motor B to be ready to engage it when Motor A again became
unwound. While that works in theory, what happens in practice is different.
As soon as spring tension in Motor A is equal to spring tension in
Motor B, everything stops. Motor B can never rewind Motor A past the
point of equal spring tension, and Motor A can’t function until it
can release the tension on its spring, which is prevented by the tension
of Motor B’s spring.
It worked on paper, and Jake apparently assumed that it would also
work in fact. He decided to stage a grand exhibition of his improved
machine, which could fly much farther than the original. There’s some
disagreement about where the demonstration took place. Some say it
was in San Antonio’s
San Pedro Park, some claim it was in a park near Boerne,
and some say it was in Fredericksburg.
Wherever it was, Jake got the machine off the ground in good shape
and flew until the main motor was exhausted. Then he engaged the second
motor to rewind the first. Spring tension equaled and both motors
quit. As Jake did his best to solve the unexpected situation, the
machine flew into a large liveoak and crashed. That did it. Backing
was withdrawn and Jake was back to the beginning.
Jake Brodbeck didn’t give up on the idea of flying. He was at the
World’s Fair in St. Louis in 1900, carrying copies of all his drawings
and specs, trying to get someone to finance building of another machine.
While he was there, someone stole his papers. The crime was never
December, 1903, at Kitty Hawk, North Carolina, a couple of bicycle
makers from Ohio, Wilbur and Orville Wright, launched a flying machine
of their own from the seashore’s sand. It was a biplane. It had no
actual fuselage—instead, the pilot lay on his belly on the lower wing.
For power it had an internal-combustion engine. It also had a forward
canard, very similar to the one on Jake’s machine.
Jake’s machine needed a forward canard because it left the launching
ramp in a nose-up condition with very low power. Without the forward
canard it would have been subject to stalling almost immediately.
However, the Wright machine took off from level ground, not in a nose-up
condition, with considerably more power than the Brodbeck machine.
Why, then, was a forward canard needed? Or could it be that the Wrights
came across some specs for a flying machine different from their own
but acknowledged to have been successfully flown, which had a forward
canard—so they incorporated the forward canard into their own design?
Nobody knows that answer.
At Fort Sam Houston, in San
Antonio—the birthplace of American military aviation—on the 75th
anniversary of the arrival of LT Benjamin Foulois and the first US
military airplane, a Wright type B, descendants of Jacob Brodbeck
were recognized by Air Force historians for Jake’s contribution to
manned, heavier-than-air flight. For Jake’s building and flying the
first known airplane in world history.
