An airplane—also called a plane, or an aeroplane in Commonwealth English—is a fixed-wing aircraft that moves forward using thrust from a jet engine, propeller, or rocket engine. These machines come in many sizes, shapes, and wing designs. Their uses span recreation, moving people and goods, military operations, and research.
Worldwide, commercial aviation carries over four billion passengers each year on airliners, and moves more than 200 billion tonne-kilometers of cargo annually—though that accounts for less than 1% of global cargo transport. Most airplanes have a pilot on board, but some, like drones, are controlled remotely or by computer.
The first airplane was invented and flown by the Wright brothers in 1903, recognized as the first sustained, controlled, heavier-than-air powered flight. Their work built on earlier advances: George Cayley outlined the modern airplane concept in 1799, later building models and successful passenger-carrying gliders; and Otto Lilienthal, a German pioneer, studied heavier-than-air flight between 1867 and 1896, with his 1891 attempts seen as the start of human flight.
After limited use in World War I, aircraft technology kept advancing. Airplanes were present in all major battles of World War II. The first jet aircraft, the German Heinkel He 178, appeared in 1939. The first jet airliner, the de Havilland Comet, entered service in 1952. The Boeing 707, the first widely successful commercial jet, operated from 1958 to 2019—over 60 years.
**Etymology and usage** The words *airplane* and *aeroplane* first appeared in English in the late 19th century, before powered flight. They come from the French *aéroplane*, which combines the Greek *aēr* (“air”) with either Latin *planus* (“level”) or Greek *planos* (“wandering”). Originally, *aéroplane* referred only to the wing—a plane moving through air. Through synecdoche, the word for the wing came to mean the whole aircraft. In the United States and Canada, “airplane” is used for powered fixed-wing aircraft. In the United Kingdom, Ireland, and most of the Commonwealth, “aeroplane” is more common. According to the Oxford English Dictionary, “airplane” became the standard U.S. term after the National Advisory Committee for Aeronautics adopted it in 1916, replacing “aeroplane.”
**History** *Antecedents* Ancient stories, like the Greek myth of Icarus and Daedalus or the Vimana in Indian epics, describe flight. Around 400 BC in Greece, Archytas supposedly built a bird-shaped, self-propelled model that flew about 200 meters using a steam jet—though it may have been suspended. Later attempts include the 9th-century Andalusian poet Abbas ibn Firnas and the 11th-century English monk Eilmer of Malmesbury, both of whom tried gliders and were injured. Leonardo da Vinci studied bird wings and designed a man-powered aircraft in his 1502 *Codex on the Flight of Birds*, first noting the difference between a bird’s center of mass and center of pressure.
In 1799, George Cayley proposed the modern airplane as a fixed-wing machine with separate systems for lift, propulsion, and control. He built and flew fixed-wing models by 1803 and a successful passenger-carrying glider in 1853. In 1856, Frenchman Jean-Marie Le Bris achieved the first powered flight by having a horse pull his glider, “L’Albatros artificiel,” along a beach. Russian Alexander F. Mozhaisky also made innovative designs. In 1883, American John J. Montgomery flew a glider under control. Other glider pioneers included Otto Lilienthal, Percy Pilcher, and Octave Chanute.
Sir Hiram Maxim built a 3.5-ton craft with a 110-foot wingspan, powered by two 360-horsepower steam engines driving two propellers. In 1894, it was tested with overhead rails to prevent rising; the test showed it could lift off, but instability led Maxim to abandon the project. Between 1867 and 1896, Otto Lilienthal developed heavier-than-air flight, making well-documented, repeated gliding flights. He developed the modern wing concept, and his 1891 attempts are considered the start of human flight. His “Lilienthal Normalsegelapparat” is seen as the first series-produced airplane, and his work heavily influenced the Wright brothers.
In the 1890s, Lawrence Hargrave studied wing structures and created a box kite that could lift a person. His box kite designs were widely used. He also developed a type of rotary aircraft engine but never built or flew a powered fixed-wing aircraft.
*Early powered flights* Frenchman Clement Ader built his first flying machine, the Éole, in 1886. It was bat-shaped, with a lightweight steam engine of his own design (four cylinders, 20 horsepower) driving a four-blade propeller. The engine weighed no more than 4 kilograms per kilowatt. The wings spanned 14 meters, and the total weight was 300 kilograms. On 9 October 1890, Ader attempted to fly the Éole. Aviation historians credit this as a powered takeoff and uncontrolled hop of about 50 meters at a height...
Lore & Background
Following its limited use in World War I, aircraft technology continued to develop. Airplanes had a presence in all the major battles of World War II.
Reader's Guide
The airplane revolutionized transportation, warfare, and global commerce. Most airplanes are flown by a pilot on board, but some are remotely or computer-controlled, such as drones. Airplanes have been essential in military strategy, from World War I observation platforms to World War II campaigns like the Blitzkrieg and the Battle of Britain.
Did You Know?
- The word 'airplane' derives from the French 'aéroplane', which originally referred only to the wing.
- The Wright brothers credited Otto Lilienthal as a major inspiration for their decision to pursue manned flight.
From Myth to Machine: The Long Road to Flight
Long before any human left the ground, cultures worldwide dreamed of flight. Greek storytellers gave us Icarus and Daedalus, while ancient Indian epics described the Vimana, a celestial vehicle. Around 400 BC, Archytas of Greece crafted a bird-shaped model driven by a jet of steam, traveling roughly 200 meters. Later, 9th-century poet Abbas ibn Firnas and 11th-century monk Eilmer of Malmesbury attempted glider flights, both injured. Leonardo da Vinci, in his 1502 Codex on the Flight of Birds, studied avian wing design and identified the distinction between center of mass and center of pressure. The true blueprint for the modern airplane arrived in 1799, when George Cayley proposed a fixed-wing machine with separate systems for lift, propulsion, and control. He flew models by 1803 and a passenger-carrying glider by 1853. Otto Lilienthal then made well-documented, repeated gliding flights between 1867 and 1896, developing what is considered the first series-produced airplane. Clement Ader's steam-powered Éole achieved a short uncontrolled hop in 1890. All this groundwork culminated in 1903, when the Wright brothers achieved what the FAI recognizes as the first sustained and controlled heavier-than-air powered flight. By 1905, their Flyer III could fly stable, controllable circuits for extended periods.
The Jet Revolution and the Age of Mass Air Travel
Airplanes first saw limited military use during World War I, but World War II cemented their role in every major battle of the conflict. The postwar decades brought a technological revolution that transformed aviation from a novelty into the backbone of global connectivity. In 1939, Germany's Heinkel He 178 became the world's first jet-powered aircraft, and in 1952 the de Havilland Comet entered service as the first jet airliner. Yet it was the Boeing 707, which began commercial operations in 1958, that truly democratized air travel. As the first widely successful commercial jet, the 707 remained in service for more than sixty years, flying until 2019. Today, the fruits of that jet-age revolution are staggering: commercial aviation carries over four billion passengers each year and moves more than 200 billion tonne-kilometers of cargo annually. Even so, air freight accounts for less than one percent of total global cargo movement, a reminder that the airplane remains one thread in a vast logistical tapestry. The trajectory from a limited wartime tool to a machine shuttling billions of people and goods across continents is one of the most dramatic technological arcs of the modern era.
A Word in the Air: Etymology and Regional Identity
The word we use to describe one of humanity's greatest inventions has a surprisingly layered linguistic history. First attested in English in the late 19th century—before any sustained powered flight had even occurred—"airplane" and its Commonwealth cousin "aeroplane" both trace back to the French aéroplane. That French term, in turn, is built from the Greek aēr, meaning "air," combined with either the Latin planus, "level," or the Greek planos, "wandering." Originally, aéroplane referred only to the wing itself, a flat plane moving through the air. Through a process linguists call synecdoche, the name for the component gradually absorbed the identity of the whole machine. The split between "airplane" and "aeroplane" is largely geographic. In the United States and Canada, "airplane" is the standard term for powered fixed-wing aircraft. In the United Kingdom, Ireland, and most of the Commonwealth, "aeroplane" is the preferred spelling. According to the Oxford English Dictionary, the American form became standard after the National Advisory Committee for Aeronautics adopted it in 1916, effectively replacing the earlier "aeroplane" in U.S. usage. A single machine, then, carries two names that encode both its engineering roots and the cultural boundaries of the English-speaking world.
Beyond the Cockpit: Scope, Scale, and the Drone Frontier
An airplane is, at its core, a fixed-wing aircraft driven forward by thrust generated from a jet engine, a propeller, or even a rocket engine. But that simple definition belies an extraordinary range of form and function. Airplanes come in a vast spectrum of sizes, shapes, and wing configurations, tailored to tasks as varied as recreational flying, the transportation of people and goods, military operations, and scientific research. For the overwhelming majority of these aircraft, a human pilot sits on board, making real-time decisions about altitude, heading, and speed. Yet a growing subset of fixed-wing machines is designed to fly without anyone aboard at all. Drones—remotely piloted or fully computer-controlled—represent a frontier where the traditional boundary between operator and aircraft dissolves. Whether a propeller-driven recreation craft, a jet-powered transport carrying people and goods, or a computer-controlled research platform, the airplane remains a single concept expressed in countless configurations. Its versatility, spanning leisure to warfare to discovery, is what makes it one of the most adaptable machines ever devised by human hands.
