Flight is the process of moving through the air, typically by means of an aircraft. It is a fundamental aspect of aviation and has been a significant mode of transportation since the early 20th century. The principles of flight are governed by the four forces of flight: lift, weight, thrust, and drag. Lift is generated by the wings of an aircraft, which are designed to create an upward force that counteracts the force of gravity, allowing the aircraft to rise and stay airborne. Thrust is provided by the aircraft's engines, which propel it forward. Drag is the resistance encountered by the aircraft as it moves through the air, and weight is the force of gravity acting on the aircraft. The balance of these four forces determines the aircraft's performance and stability in flight.

The history of flight dates back to the ancient world, with early attempts at human flight using kites and gliders. However, it was not until the late 19th and early 20th centuries that significant advancements were made. The Wright brothers, Orville and Wilbur, are credited with inventing and building the world's first successful airplane and making the first controlled, powered and sustained human flight on December 17, 1903. Since then, flight has evolved significantly, with the development of various types of aircraft, including fixed-wing aircraft, rotary-wing aircraft, and jet aircraft.

Flight is used for a variety of purposes, including passenger transportation, cargo transportation, military operations, and recreational activities. It has revolutionized the way people and goods are transported, enabling long-distance travel and facilitating global connectivity. However, flight also presents challenges, such as air traffic control, safety regulations, and environmental concerns related to emissions and noise pollution. Despite these challenges, flight remains a vital and essential mode of transportation and exploration.
