Various Aircraft
The airplane is one of the most important inventions in the early 20th century, and it is recognized that it was invented by the American Wright brothers. Their flight on December 17, 1903, was recognized by the Federation of International Aviation (FAI) as "the first controlled sustained powered flight of a heavier-than-air aircraft", the same year they founded the "Wright Aircraft Company" .
Since the invention of the airplane, the airplane has increasingly become an indispensable tool for modern civilization. It has profoundly changed and influenced people's lives, and started the history of people's conquest of the blue sky.
