Aviation milestones mark significant achievements in the history of flight. One of the earliest milestones was the Wright brothers' first powered flight in 1903, which took place in Kitty Hawk, North Carolina. This event demonstrated that controlled, sustained flight was possible, paving the way for future advancements in aviation technology. Another key milestone occurred in 1969 with the introduction of the Boeing 747, the first wide-body airliner. This aircraft revolutionized air travel by increasing passenger capacity and reducing costs, making flying more accessible to the general public. These milestones highlight the evolution of aviation and its impact on global transportation.
