The Wright Brothers, Orville and Wilbur, are the men who are credited with producing the first controlled, powered, heavier-than-air human flight on December 17, 1903. The aircraft flew for a total of 12 seconds for 120 feet. This event is incredibly important because it obviously led to the creation of many other types of planes and various other air crafts such as helicopters and military planes.
I think that the creation of the airplane is an important event because today we are able to travel to places that people back then could only get to by boat. Traveling by air is much quicker than traveling by boat or car. It has made traveling more efficient and easier to do because you don't have to be in a cramped little car for more than 3 hours or spend a day or two on a boat getting sea-sick.
