Flight
“For once you have tasted flight, you will walk the earth with your eyes turned skyward, for there you have been and there you will long to return.” — attributed to Leonardo da Vinci
Powered flight conquered humanity’s oldest aspiration — to take to the sky. Within decades of the first flights, aircraft transformed warfare, commerce, and the very perception of distance.

Historical Background
On 17 December 1903, Orville and Wilbur Wright achieved the first sustained, controlled, powered heavier-than-air flight at Kitty Hawk, North Carolina. Their Flyer covered just 37 metres in 12 seconds — within 66 years, humans would walk on the Moon. The pace of aviation development was breathtaking: by the First World War, barely a decade later, aircraft were being used for reconnaissance, bombing, and aerial combat.
Military aviation matured rapidly. Fighter aircraft — initially flimsy biplanes armed with machine guns synchronised to fire through the propeller — evolved into fast, heavily armed monoplanes by the late 1930s. The Battle of Britain (1940) demonstrated that air superiority could determine the outcome of a campaign. Anti-aircraft defences developed in parallel, from simple machine gun positions to radar-directed batteries of heavy guns. Airports became essential military and civilian infrastructure, enabling rapid deployment of forces and the global movement of goods and people that defines the modern era.
