This was only one of the progenitors and scarcely the most advanced.

George Cayley laid a lot of the groundwork which was taken up by
pioneers such as Henson, Stringfellow and Lillienthal

Henson was experimenting with gliders and lightweight steam engines
in the 1840's and published his patent (no. 9478) in 1842. This described
a machine with bamboo spars and diagonal wire bracing. The surface of the
planes was to amount to 4,500 square feet, and the tail, triangular in form
was to be 1,500 square feet. The driving power was to be supplied by a
steam engine of 25 to 30 horse-power, driving two six-bladed propellers.

John Stringfellow flew his first steam powered flying machine in 1848 and
his triplane of 1868
is on display in the Early Flight Gallery of the National Air & Space
Museum,
Washington, DC

Otto Lilienthal's work is of course seminal and laid much of the foundations
of what is noiwadays referred to as aerodynamics. In particular his
analysis
of different wing constructions and aspect ratio, wing shape and profile,
based on his experiments were invaluable to those who followed.

The Planophore (1871) flew farther and longer than the Wright Flyer
and was more stable. Langley, Chanute, and the Wrights all
acknowledged Penaud's accomplishments.
Got something else to say? (Of course he does... he ALWAYS does)

Sure it did but it was a model powered by a rubber band.
A machine capable of carrying a man is a rather more advanced
device and while it may have flown longer than the Wrights first flight the
they assuredly beat its record fairly quickly.

Nobody is denying Penaud certainly did good work but he was one on many.

This is a discussion group old boy, of course other people have
something to say.

The current world record for paper airplanes flew farther and longer
than the Wright Flyer...

You simply cannot get over the fact that the first powered, heavier
than air piloted aircraft was built an flown by Americans and not your
Germanic super men, can you?

Brothers. His feat, however, did not get the publicity it deserved.

Without his building a wind-tunnel, nothing he did could be understood,
or repeated.

The Wright Brothers were the first people to understand the physics required
to create lift, and thrust. Having flown gliders for several years, they developed
a method for controlled flight. The only thing they didn't figure out first, was that
ailerons beat wing-warping, and regardless of any lawsuit, they missed the boat
on that.

All other claims to previous controlled flight are bogus.

Buying into that NASM crap again Al? The Gustave Weisskopf GW No.21
flew in 1901- two years before the Wrights and it was witnessed by
hundreds of people and reported in the local newspaper. But because
the scientific reporter did not like taking photos (preferring to
sketch instead) and the fact that Herr Weisskopf was not a US
citizen... he has been deliberately and conveniently dismissed. It
probably helped that the Wrights pressured the US to declare their
aircraft the first in order to recieve their permission to display
their aircraft in the US and the fact that Weisskopf tried to
concentrate on early aviation motors- his personal business that
ultimately failed which led him back to Germany and his death.
The Wrights have stated that the GW.21 "could have never flown" due to
its construction. But they were proven wrong by two different
replicas, one flown here in the US by a historic society and the
second in Germany with a Luftwaffe pilot at the controls.
BTW, who cares about the Wrights? The Germans had Lilienthal's gliders
and the Zeppelins.

Hence my appeal to any Aussies out there who might have leads or further
info. Could it have been a true story I read? Did an Aussie first do the
deed? Thanks for any assistance.


You're thinking of Richard Pearse. While some Australians claim Pearse flew
before the Wrights, Pearse himself never made such a claim. An examination
of available data on Pearse's machines suggests it's very unlikely Pearse's
machine ever achieved powered flight of any kind.
