Despite 25 years of evidence to the contrary, American pilot and inventor
Leonard Warden Bonney believed the secret to manned flight was to
emulate the birds as closely as possible. To this end he kept and studied seagulls
and devised an aircraft on avian principles. The Bonney Gull emerged in late
1927 and was unlike anything before or since. The wings, which really can be
described as gull-like, did everything except actually flap, incorporating variable
incidence, variable dihedral, and variable sweep of the outer sections. After four
years' work and considerable testing in wind tunnels and on the ground, and
despite the protest of friends and observers, Bonney took off in the Gull on 4
May 1928. The Gull wobbled, fishtailed and plunged into the ground, killing
Bonney and ending his dream of flying like the birds.

It means man can not mimic the flight of birds

"Despite 25 years of evidence to the contrary, American pilot and inventor Leonard Warden Bonney believed the secret to manned flight was to emulate the birds as closely as possible."
I do not get this statement. Do you mean nature does not know any examples of flying animals? Or do you mean that man cannot mimic natural bird flight properties to a full 100 procent? Was the statement only valid in 1927 or is it still valid today?

quem e que foi idiota a suficiente para fazer isso
Do you have any comments about this aircraft ?
FACTS AND FIGURES
© The wings of the Gull could
fold backwards for road
transport or storage.
© The all-metal Gull had side-byside
seating, dual controls and
© The tail consisted of a small fixed
surface and a large rudder,
emulating a bird's tail feathers.
© The angle of incidence of the wing
couid be varied, as could its dihedral
and the sweep of the rips. All of this
was handled by a 'minimum amount
of central controls'.
