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

Their 1901 Wind Tunnel system revolutionized the study of aeronautics

Only the second to be built in the US, the wind tunnel allowed the brothers to study how air moves around more than 200 different wing shapes. This data helped them refine a key math equation, long held as the standard, that had been based only on one wing shape.

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 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.

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.

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 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.

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.

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.

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

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.

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.

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.

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.

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 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.

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.

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.

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.

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.

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 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.

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.

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.

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.

How birds are becoming research assistants

Through the creation of tiny sensors easily placed on their bodies, birds have served as research assistants for various scientists. With untold numbers of birds sending back data, researchers have achieved greater insights in long obscure areas of meteorology, ecology, and more. For example, weather scientists use high-flying birds to outline the height of the planetary boundary layer, while conservationists track gulls to protect migrating whales. Learn more here.

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 Wrights descended from English-born migrants to Boston in the 1630s

Samuel Wright was a Puritan who arrived in Massachusetts just two decades after the Pilgrims. His great-great-grandson Daniel Wright, born in Connecticut in 1757, fought in the Continental Army during the American Revolution, seeing action at the Battle of Saratoga.

For the same cost, turbines with three blades are the most resilient

Odd-numbered blade values more evenly distribute wind loads across the face of rotors, reducing bending and twisting forces on the turbine that cause wear. Modeling shows that three blades optimize efficiency and cost for everyday wind speeds.

How neutron stars serve as laboratories for testing Einstein's theory of gravity

Data from a 16-year study of an orbiting pair of spinning neutron stars showed that measurements of gravitational wave energy and the bending of light around the system were consistent with predictions made by general relativity to an accuracy of at least 99.99% across seven tests.

Validation of the greenhouse effect may have been misattributed

Although Irish physicist John Tyndall showed in 1859 that water vapor and carbon dioxide could absorb and radiate infrared radiation, experiments by American scientist Eunice Foote three years earlier identified the same phenomenon for light in general. Historically overshadowed, her work was rediscovered by female historians over a century later.

See technicians use rappelling gear to make wind turbine repairs from 35+ stories up

Although drones are used to conduct initial reviews from the ground, mechanical engineers trained in turbine maintenance face extreme risks during close inspections more than 150 meters off the ground.

Wind helps trees develop resistance to collapse

Scientists at Biosphere 2 found that trees grew faster in the facility than those in the wild but collapsed more quickly when replanted outdoors. Researchers uncovered that trees build resistance when pushed and pulled due to wind stress, strengthening their foundational root systems.

This short video surveys the flat, empty expanse near Kill Devil Hills in North Carolina’s barrier islands, highlighting the area’s attractive conditions for early flight. Also shown are the stone monument to the Wright’s and replica wooden shacks like the ones they lived in those fateful years.

Uncertainties in measurements make finding gravity's Newtonian limit unclear

Although Newton's "universal" law is unreliable in strong gravitational fields when compared with the field equations of general relativity, it is still taught for its accuracy on everyday scales. However, gravity's effect on small scales is too weak to be measured reliably, its accuracy at atomic scales remains unknown.

The greenhouse effect was discovered by analyzing Earth's temperature

Using mathematical techniques developed to analyze heat transfer, Jean-Baptiste Joseph Fourier showed that Earth should be significantly cooler if solar radiation were the only contributor to its surface temperature. By considering that the atmosphere could amplify the sun's warming effect, he formulated what became known as the greenhouse effect.

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.

Bill Bowerman got the idea for the breakthrough waffle-knit running shoe from a waffle iron

Nike cofounder Bill Bowerman was trying to find new ways to create traction for his runners on artificial turf. He looked at the waffle iron and realized that the pattern would work for the shoes’ soles.

How a Harlem Renaissance poet teamed up with a Wright brother

Paul Laurence Dunbar is one of the most influential poets from the Harlem Renaissance, a loose collection of Black artists who redefined American literature in the early 20th century. He was also an entrepreneur. He founded a short-lived newspaper, the Dayton Tattler, alongside Orville Wright, one of the famous Wright Brothers who pioneered aviation. This article explores how their friendship defied the societal norms of the time and led to a pioneering publication.

Scientists validated Albert Einstein's theory of gravity by measuring the apparent positions of stars via their starlight as it traveled near the sun on its way to Earth during a total solar eclipse.

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.

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.

Mosquitoes stop flying at wind speeds equivalent to the swishing of a horse's tail.

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.
