Leonardo Davinci. He never had a working model or even a model for that matter - but he still designed one.
the wright brothers == While the Wright brother made the first WORKING aircraft, Leonardo da vinci designed the first one. It's in his notebooks.
It might be necessary for you to clarify what you mean by "successful." If you are referring to the first successful AIRPLANE FLIGHT, then that would be the one the Wright Brothers made on December 17, 1903 at Kitty Hawk NC. But, if you are referring to the first FINANCIALLY SUCCESSFUL airplane, then I don't have an answer for you, at this time.
the wright brothers (a.k.a Orvil and Wilbur wright).
Orville and Wilbur Wright
The Wrights did NOT make the first flight. -Many people before them made short and less successful flights.
The first airplane was made and flown by brothers Wilbur and Orville Wright in 1903.
The first aircraft made in the US around 1900. -Many people were building and testing them, and no exact date is available.
No, he made aircraft models but his two full size aircraft were failures.
Almost all of the first aircraft engines were air cooled as this made for a lighter engine.
The hot-air balloon of the brothers Montgolfier, generally understood to be the first aircraft, was made in 1783.
They made at least 2 gliders before their first powered aircraft.
Aircraft can be made of almost anything. The first ones were only wood and cloth.
In 1848 John Stringfellow made a steam engine that was able to carry a model aircraft. The earliest aircraft engine capable of powering a passenger plane was made in 1906 by Leon Levavasseur. The first mass produced aircraft engine was made in 1908 by Gnome Omega.
Glenn Curtiss made the first aircraft for the US Navy
Clyde Cessna built his first aircraft in 1911
The first aircraft made in the US around 1900. -Many people were building and testing them, and no exact date is available.
they made the first powerd aircraft in only three hours.
The first Airbus aircraft flew in 1972. They are still making aircraft today (Mid-2013).
No, he made aircraft models but his two full size aircraft were failures.
The Supermarine Aircraft company made most of the Spitfires.
Almost all of the first aircraft engines were air cooled as this made for a lighter engine.
The first monkeys in space were NOT in an aircraft, but in a V2 rocket made in Germany in WW2 and brought to USA after the war.
The hot-air balloon of the brothers Montgolfier, generally understood to be the first aircraft, was made in 1783.
