Today, the aviation industry encompasses a vast network of airlines, manufacturers, regulatory bodies, and support services, all working together to ensure the safe and reliable movement of people and goods around the globe. The impact of flight is felt in everyday life, from the convenience of cross-country trips to the rapid delivery of essential supplies. As new technologies emerge and sustainability becomes a central concern, the future of flight promises to be as transformative as its past.

Historical Development of Flight

The aspiration to fly dates back thousands of years, with early legends and artistic depictions reflecting humanity's fascination with the skies. However, practical progress began in the late 18th and 19th centuries, with the invention of hot air balloons by the Montgolfier brothers and the development of gliders by pioneers like Otto Lilienthal. The true breakthrough came in 1903 when Orville and Wilbur Wright achieved the first powered, controlled, and sustained flight in Kitty Hawk, North Carolina. Their success laid the foundation for rapid advancements in aircraft design, propulsion, and aerodynamics throughout the 20th century.
