From fragile balloons drifting over 18th-century cities to drones redefining modern warfare, aviation has been one of the most transformative technologies of the last century. In a recent video explainer, Dr. Waqar Zaidi traces how flight reshaped warfare, mobility and global connectivity across the twentieth century, and why its influence continues to grow.
Modern aviation, as we understand it today, began in 1903 with the Wright brothers’ first successful fixed-wing flight. This breakthrough marked the transition from lighter-than-air travel to powered aircraft, opening a new era almost overnight. Aviation spread rapidly, driven initially by military demand. During the First World War, aircraft were first deployed for reconnaissance, offering armies a new vantage point over the battlefield. By the war’s end, they had evolved into instruments of bombing, permanently altering the nature of conflict.
The twentieth century’s major wars, from the Second World War to Korea and Vietnam, were shaped decisively by air power. Heavy aerial bombardment caused unprecedented destruction and civilian casualties, embedding aviation at the heart of modern warfare. Yet aviation’s legacy is not only one of violence. On the civilian front, aircraft began as tools for airmail before quickly expanding into passenger transport and cargo. The decades following the Second World War saw rapid technological advances, particularly the shift from piston engines to jet aircraft.
The arrival of jet airliners in the 1960s ushered in an age of mass travel. Flying became faster, cheaper and accessible to millions, accelerating through the 1970s and 1980s to the present day, when billions of passengers travel by air each year. Aviation, Dr Zaidi argues, played a crucial role in shaping the globalised world, shrinking distances, enabling migration, and intensifying international exchange.
Beyond piloted aircraft, aviation’s reach expanded into aerospace technologies. Rockets, missiles and satellites, many developed during the Cold War, transformed both warfare and communication. Satellites, in particular, became indispensable to global infrastructure from the 1960s onwards. Today, navigation, communication and surveillance all depend on them.
The story of aviation is still unfolding. Unmanned aerial vehicles, or drones, are increasingly prominent, not only in modern conflicts but also in mapping, exploration and delivery services. As innovation continues, aviation remains central to how humanity moves, communicates and wages war, its influence set to deepen rather than fade.
