Their 1901 Wind Tunnel system revolutionized the study of aeronautics

Using wind tunnels, the brothers corrected a centuries-old error used to measure lift

When their early gliders failed, the Wright brothers scrutinized inherited data analysis. Smeaton’s coefficient had been used to calculate the density of air (0.005) for centuries. The Wright’s data validation through the use of small, laboratory wind tunnels showed the correct number was 0.0033.

The Wright Flyer was an engineering breakthrough, and modern aircraft still use the same principles of flight.

The pair began their aviation research by studying the 'mechanics' of birds

Taking inspiration from gliding pioneer Otto Lilienthal—whose gliders resembled the wings of birds—Wilbur took to observing birds to understand how they do it, in order to solve the problem of flight. This opening episode on the brothers explores their lives and accomplishments.

The 1910 Wright Model B was the brother’s most successful aircraft

The model, built from 1910 to 1914, was the first designed to be constructed in bulk, with four built each month in 1911 and 1912. The two-seater was used in exhibition flights and training for some of the earliest uses of airplanes in military contexts.

Wilbur published key papers, gave speeches in the burgeoning aviation community

Much of the theoretical work is credited to Wilbur, whose scientific mind observed birds and early pioneers to discover the key problem to solve was control. This 1901 speech surveys the recent work in the field and showcases what the brothers worked on two years before their breakthrough flight.

The brothers’ most intense period of creativity and progress came between 1901 and 1910, when their work at Kitty Hawk culminated in the first powered flight. The pair, however, were not the most business-savvy, and they struggled to take financial advantage of their pioneering work in the field.

The Wrights’ patent battles delayed the development of aviation technology in the US

By the time World War I began in 1914, the US was lagging behind European powers in aviation. This stemmed primarily from wars over patents between the Wrights and competitor Glenn Curtiss. The pair argued their 1906 patent covered all mechanisms enabling lateral flight.

Before their historic flight, the Wright brothers ran a bicycle shop in Dayton, Ohio, where they built the world's first successful powered aircraft.

How did the Wright brothers invent the airplane?

This article explores the research processes that led Wilbur and Orville Wright to invent the airplane and includes photos and visualizations of their findings and inventions.

Watch an amateur fly a 1902 Wright glider at the Kitty Hawk dunes

Billy Vaughan recreates the test flights of the Wright gliders in the exact location the brothers conducted them. He argues an October 1902 glider flight—not the December 1903 one—was the key innovative moment, implementing three-axis control. Host Baratunde rides a glider in perfect windy conditions in this re-creation.

The Wrights battled inventor Glenn Curtiss for market dominance, ultimately losing

Their 1903 flights were met with skepticism, and the pair were hesitant to conduct public demonstrations. By 1908, Curtiss developed his own airplane, successfully flying a mile in front of judges and winning the nation’s first pilot license. The Wrights sued for patent infringement, sparking a business war.

Wind turbines are limited to capturing no more than 59.3% of incoming wind energy

In 1919, German physicist Albert Betz applied the laws of conservation of mass and momentum to airstreams to calculate the theoretical limit. However, real-world turbines only convert 35 to 45% of available wind energy into electricity.

The Wrights were inspired by a toy helicopter as kids

The pair tinkered with toys and dreamed of building a flying machine at a young age. Founders Podcast host David Senra read David McCullough's 2015 book on the duo and distilled key insights for leaders to take from their work and lives, focusing on their relentless resourcefulness.

Kitty Hawk’s wide space, isolation and winds were ideal for flight experiments

North Carolina’s Outer Banks at the turn of the 20th century were not the summer resort destinations they are today. The brothers sought privacy as they toyed with their aviation designs, camping in Kill Devil Hills and using its sand dunes as launch points for early glider designs.

In the 1940s, pilots flew into thunderstorms to learn about their formation and properties as part of the Thunderstorm Project, the first multiagency meteorological study mandated and funded by Congress.

Orville and Wilbur argued over everything, likely accelerating their progress

The two never married, and focused solely on their goal of achieving flight. While both were socially reserved, they were passionate about their project, regularly debating—even shouting—over the details of propellers, engines, wings and more. This video explores how their culture of open argument likely fueled their discoveries.

Famed historian David McCullough on five things to know about the Wrights

The bestselling author of popular, beloved histories on US presidents, engineering feats and disasters published a study of the Wrights in 2015. Here. he highlights five key facts to know about the brothers, including that their efforts were bootstrapped—meaning they paid for their work themselves with no outside investors.

Watch a 1908 Wright Flyer demo with Wilbur and a passenger near Le Mans, France

One of the earliest filmed flights, this demonstration in France helped dispel doubts over the Wrights’ claims to powered, controlled flight. Such demos helped launch the pair to fame five years after their seminal flight in Kitty Hawk.

NASA uses a specialized plasma wind tunnel to test heat shield technology

The ArcJet Complex ionizes compressed air that fires onto shields at hypersonic speeds, replicating the conditions of high-speed, planetary reentry. An enhanced facility incorporates lasers to mimic the radiant heating experienced during high-energy atmospheric traversal.

The public mostly doubted the Wrights’ flight claims for five years

Coverage of the pair’s success often described them as barely educated bike mechanics. They struggled to gain traction with the public. It took interest from French business leaders and the US Signal Corps to bring the pair into separate demonstrations of their planes.

Turbulence is needed to make airplanes more stable and golf balls fly farther

Vortex generators—small fins placed along airplane wings—create small eddies that prevent airflow separation, maintaining lift and preventing stalls. Golf balls have dimples that create a turbulent boundary layer on their surface, minimizing drag forces.

Hurricane conditions are created in a University of Miami wind-wave tank

The SUrge-STructure-Atmosphere INteraction Wind Wave Laboratory contains a 38,000-gallon wave pool connected to a wind tunnel that can generate air currents of up to 155 mph. SUSTAIN allows scientists to study how the atmosphere interacts with the ocean in extreme weather.

Airplanes generate enough lift to fly by accelerating air faster over their moving wings, which makes the pressure above the wings lower than the pressure below.

Some claim the Wrights weren’t first in flight

Their scientific and engineering achievements aside, the Wrights’ claim to be first in flight is debated—and rejected—by some in the industry. Other early pioneers like Gustave Whitehead or Alberto Santos-Damonto are said to deserve the title.

The Wright brothers' sister hyped their work, and was the only one to attend college

Katharine Wright became the de facto household caretaker after their mother, Susan, died, when Katharine was 15. After graduating from Oberlin, Katharine took over household duties so her father and brothers could work. She promoted their work in the US and abroad.

The Flyer sat in a shed for 13 years behind the brothers’ Dayton bike shop

While the wood is the same used in the 1903 flight, the muslin has been replaced twice. After laying forgotten in sheds, the vehicle eventually took on national importance. However, the Smithsonian Institution did not recognize it until the 1940s, after it spent time at the Science Museum in London.

The life of Edward Lorenz, who originally used a seagull in his 'butterfly effect' metaphor

By accidentally finding that rounding one variable to its third decimal place and re-running a weather simulation produced a drastically different two-month forecast, the American mathematician established the field of chaos theory. His paper—"Predictability: Does the Flap of a Butterfly's Wings in Brazil Set off a Tornado in Texas?"—introduced the well-known metaphor for the behavior of chaotic systems.

100 years of passenger air travel: a visual guide

This interactive timeline covers the first 100 years of passenger air travel, which was created in 1925 when the U.S. Post Office allowed private airlines to start delivering mail.

Turbulence has been called the most important unsolved problem in classical physics

Despite being the most common type of fluid flow in our world, scientists have struggled to model turbulent flow accurately. Though behaving unpredictably, understanding inertia and viscosity can help determine whether turbulence will occur.

Wind turbines explained

Wind turbines have powered homes since 1887, and today they’re stronger, quieter, and more reliable than ever. Offshore wind could power millions and grow fast enough to meet climate goals.

Tornado formation relies on wind shear to create a tube of rotating air

Once a horizontal vortex is created by air circulating between winds of different directions and speeds, an updraft, such as those seen in powerful thunderstorms, tilts the vortex vertically. The updraft then strengthens the vortex, which becomes a tornado upon touching the ground.

Since the museum’s opening in 1976, the wood-and-muslin plane has been available for public viewing with a model of Orville, the younger brother, lying on the plane’s mid-section.

Establishing the wind power grid required incentives, reliability, and affordability

Although wind was harnessed to generate electricity for individual buildings in the late 1800s, high costs, mechanical issues with turbines, and better fossil-fuel alternatives delayed wind power's widespread growth. After the oil crises of the 1970s, governments sought alternative energy sources and, in the decades that followed, provided tax credits to expand the wind power market.

The invention of the barometer proved that air has weight

The instrument measures air pressure by creating a partial vacuum—a region with very low density—which serves as the basis for how suction works. Mercury-based barometers were used until 2007, when they were restricted due to mercury's toxicity.

The origin of atmospheric science while testing nuclear weapons during the Cold War

The arms race between the US and the Soviet Union saw both countries stockpiling and detonating hundreds of bombs underground, underwater, and in the atmosphere. To better predict where nuclear fallout would travel after these tests, scientists developed models that would serve as a foundation for those used to explain atmospheric circulation.

Designed in 1937 by Harvard graduate student Howard H. Aiken, the 'Harvard Calculator' was used by the US Navy to solve advanced physics problems.

The iconic photo of the Wright brothers' first flight was the photographer’s first

Using a then-state-of-the-art Korona V, rescue member John T. Daniels was tasked with squeezing the device’s rubber bulb the moment the plane left the wooden track on the sand. The camera produced negatives on 5 by 7 sheets of glass.

Technological advancements will make future wind turbines more efficient and quieter

Manufacturing larger, more powerful turbines will result in future wind farms requiring fewer of them to meet energy demands. Larger turbines will meet these demands while rotating at lower speeds, reducing risks to avian wildlife.

View the Lorenz attractor, a graphical solution to chaotic equations that resembles a butterfly

The discovery of chaos theory came from Edward Lorenz's computer model of the atmosphere, which used three equations to quantify atmospheric circulation. However, the chaotic evolution of this system creates wandering figure-8-like shapes—some resembling butterfly wings—as it repeatedly attempts to settle on one of two values along unique trajectories.

Watson and Crick revealed DNA's double-helix structure using others' key findings

Their 1953 model, made from cardboard cutouts, explained how DNA stores genetic information through base pairing. Rather than experimenting and collecting their own data, they incorporated patterns and data from other scientists through trial and error.

Wind is the movement of air caused by the sun's uneven heating of Earth

The tilt, curvature, and variations in Earth's surface composition across the globe cause different regions to receive different amounts of solar radiation. As the Earth spins and tries to achieve thermal equilibrium, air masses move and interact, creating wind.

Explore hundreds of the brother’s personal photographs of flights, family and dogs

Their estate offered 300 negatives to the Library of Congress in 1948 after Orville’s death, most of which were taken by the brothers between 1897 and 1928. The collection serves as a visual timeline of their adult lives.

The Navier-Stokes equations are fundamentally accurate but unsolved in 3D

The equations model fluids and have been shown to have solutions for all systems in two dimensions. Averaging and approximations let the equations be used in climate models, aerodynamics, and medicine, though their use in some systems produces nonsensical answers.
