Airplane's
Dozens of different aircraft were developed and used in WW1. There wasn't a single airplane type.
The most successful airplane ever developed is the Cessna 172. More Cessna 172's have been produced than any other airplane. Since 1956 more than 43,000 Cessna 172's have been built.
Many airplanes were developed during WW1.
They were invented and developed in the following order: -- Steam engine (first) -- Radio -- Airplane -- Television (last)
When the airplane frames were made lighter, the plane became flimsy.
The city that they FLEW it in is called Kitty Hawk but they developed it in Dayton, Ohio
Usually an invention is something new developed through study and experiment. The development of the airplane seems to fit that better than the definition of an innovation - which is something new or a change made to an existing product, idea, or field. Airplanes weren't really an improvement on an existing thing, they were carefully thought out and developed from an accumulation of knowledge and innovations in areas like aerodynamics, materials, and motors. The development of the airplane required a lot of innovations but the airplane falls solidly in the category of "invention".
