For thousands of years, humans have dreamed of taking to the skies. The quest has led from kite flying in ancient China to hydrogen-powered hot-air balloons in 18th-century France to contemporary aircraft so sophisticated they can’t be detected by radar or the human eye.
Below is a timeline of humans’ obsession with flight, from da Vinci to drones. Fasten your seatbelt and prepare for liftoff.
1505-06: Da Vinci dreams of flight, publishes his findings
Few figures in history had more detailed ideas, theories and imaginings on aviation as the Italian artist and inventor Leonardo da Vinci. His book Codex on the Flight of Birds contained thousands of notes and hundreds of sketches on the nature of flight and aerodynamic principles that would lay much of the early groundwork for—and greatly influence—the development of aviation and manmade aircraft.
November 21, 1783: First manned hot-air balloon flight
Two months after French brothers Joseph-Michel and Jacques-Étienne Montgolfier engineered a successful test flight with a duck, a sheep and a rooster as passengers, two humans ascended in a Montgolfier-designed balloon over Paris. Powered by a hand-fed fire, the paper-and-silk aircraft rose 500 vertical feet and traveled some 5.5 miles over about half an hour. But in an 18th-century version of the space race, rival balloon engineers Jacques Alexander Charles and Nicholas Louis Robert upped the ante just 10 days later. Their balloon, powered by hydrogen gas, traveled 25 miles and stayed aloft more than two hours.
1809-1810: Sir George Cayley introduces aerodynamics
At the dawn of the 19th century, English philosopher George Cayley published “On Aerial Navigation,” a radical series of papers credited with introducing the world to the study of aerodynamics. By that time, the man who came to be known as “the father of aviation” had already been the first to identify the four forces of flight (weight, lift, drag, thrust), developed the first concept of a fixed-wing flying machine and designed the first glider reported to have carried a human aloft.
September 24, 1852: Giffard's dirigible proves powered air travel is possible
Half a century before the Wright brothers took to the skies, French engineer Henri Giffard manned the first-ever powered and controllable airborne flight. Giffard, who invented the steam injector, traveled almost 17 miles from Paris to Élancourt in his “Giffard Dirigible,” a 143-foot-long, cigar-shaped airship loosely steered by a three-bladed propeller that was powered by a 250-pound, 3-horsepower engine, itself lit by a 100-pound boiler. The flight proved that a steam-powered airship could be steered and controlled.
1876: The internal combustion engine changes everything
Building on advances by French engineers, German engineer Nikolaus Otto devised a lighter, more efficient, gas-powered combustion engine, providing an alternative to the previously universal steam-powered engine. In addition to revolutionizing automobile travel, the innovation ushered in a new era of longer, more controlled aviation.
December 17, 1903: The Wright brothers become airborne—briefly
Flying from Kitty Hawk, North Carolina, brothers Orville and Wilbur Wright made the first controlled, sustained flight of a heavier-than-air aircraft. Each brother flew their wooden, gasoline-powered propeller biplane, the “Wright Flyer,” twice (four flights total), with the shortest lasting 12 seconds and the longest sustaining flight for about 59 seconds. Considered a historic event today, the feat was largely ignored by newspapers of the time, who believed the flights were too short to be important.
1907: The first helicopter lifts off
French engineer and bicycle maker Paul Cornu became the first man to ride a rotary-wing, vertical-lift aircraft, a precursor to today’s helicopter, when he was lifted about 1.5 meters off the ground for 20 seconds near Lisieux, France. Versions of the helicopter had been toyed with in the past—Italian engineer Enrico Forlanini debuted the first rotorcraft three decades prior in 1877. And it would be improved upon in the future, with American designer Igor Sikorsky introducing a more standardized version in Stratford, Connecticut in 1939. But it was Cornu’s short flight that would land him in the history books as the definitive first.
1911-12: Harriet Quimby achieves two firsts for women pilots
Journalist Harriet Quimby became the first American woman ever awarded a pilot’s license in 1911, after just four months of flight lessons. Capitalizing on her charisma and showmanship (she became as famous for her violet satin flying suit as for her attention to safety checks), Quimby achieved another first the following year when she became the first woman to fly solo across the English channel. The feat was overshadowed, however, by the sinking of the Titanic two days earlier.
October 1911: The aircraft becomes militarized
Italy became the first country to significantly incorporate aircraft into military operations when, during the Turkish-Italian war, it employed both monoplanes and airships for bombing, reconnaissance and transportation. Within a few years, aircraft would play a decisive role in the World War I.
January 1, 1914: First commercial passenger flight
On New Year’s Day, pilot Tony Jannus transported a single passenger, Mayor Abe Pheil of St. Petersburg, Florida across Tampa Bay via his flying airboat, the “St. Petersburg-Tampa Airboat Line.” The 23-mile flight (mostly along the Tampa Bay shore) cost $5.00 and would lay the foundation for the commercial airline industry.
1914-1918: World war accelerates the militarization of aircraft
World War I became the first major conflict to use aircraft on a large-scale, expanding their use in active combat. Nations appointed high-ranking generals to oversee air strategy, and a new breed of war hero emerged: the fighter pilot or “flying ace.”
According to The Illustrated Encyclopedia of Military Aircraft, France was the war’s leading aircraft manufacturer, producing nearly 68,000 planes between 1914 and 1918. Of those, nearly 53,000 were shot down, crashed or damaged.
