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.

It was a very nice toy but scarcely to be compared with a powered machine
that could carry passengers.

The current world record for paper airplanes flew farther and longer

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?
