Most commercial planes get struck by lightning multiple times a year

On average, every in-service airplane is struck by lightning once a year

The average strikes per surface area per year on Earth suggest that aircraft should only be struck once every 1,000 years, based on their size, but proximity to storm clouds' high electrical fields increases strike rates. Aircraft are designed as continuous conductive shells, causing electricity to flow along their exterior and preventing internal damage.

Watch how scientists learn about hurricanes by flying into them

A specialized fleet of Air Force planes is built to fly into hurricanes and gather critical data from inside the storm. Beyond radar and microwave sensors, the planes are equipped with dropsondes—small instruments dropped into storms to measure pressure, temperature, and wind.

Pilots are familiar with multiple types of turbulence, each with varying severity

Each type is defined based on what disrupts airflow in the atmosphere, including thunderstorms, mountains, and wakes produced by aircraft that previously took off. Pilots classify turbulence as light, moderate, severe, or extreme based on how it affects aircraft movement.

The engineers proposing massive airbags for airplanes

Though they are famously rare, airplane crashes are some of the most shocking catastrophes when they occur. These researchers are dreaming up an implausible safety feature to help crashing planes land safely.

How do you survive a plane crash?

Almost 95% of plane crashes aren’t fatal. So what separates survivors from victims? One man’s story may hold the key, plus expert tips that could save your life.

Lightning rods provide a conductive pathway to safely steer massive electric currents

The device is positioned higher above the ground to "catch" one of the many branching filaments of electrons from clouds before they make contact with other surface structures, which have been induced to have a positive charge by overhead storm clouds. The current is then sent to a conductive grid buried underground.

Scientists use ground-based radar data to detect turbulence within clouds

NCAR developed the NEXRAD Turbulence Detection Algorithm and the Graphical Turbulence Guidance system to provide forecasts up to 18 hours ahead using ground-based Doppler radar data. Software systems also utilize an automated observation and reporting package—the EDR system—found on Delta, United, and Southwest Airlines aircraft.

There are no outdoor locations that are safe from lightning

If your hair stands up amid an approaching storm, seek shelter immediately, as a local buildup of charge imbalance precedes cloud-to-ground lightning. If you are stuck outside, move to a lower altitude, such as a valley or ravine, and avoid open fields, water, and isolated tall objects. Do not lie down or crouch.

How black boxes made flying safe

Black boxes—which are actually orange—were not universally present in airplanes until roughly 1967, a process which grew out of frustration over frequent, unexplained crashes in the industry's first few decades. This piece tells the origins of...

How a panel blew off a Boeing plane in mid-air

As Alaska Airlines Flight 1282 climbed just over 16,000 feet into the sky, a refrigerator-sized panel was ripped from its side, forcing it to land. Few of the 171 passengers were injured. This infographic explains how the panel tore from the body of the Boeing 737 MAX 9 plane, which had only been in service for eight weeks.

Scientists have diverted the path of lightning using lasers

A proof of concept for a laser protection system, which could be used to protect launchpads and airports in the future, was conducted on the Säntis mountain in northeastern Switzerland. Rapid laser pulses heated air molecules, creating a more conductive, 50-meter (164-foot) path for the electrical discharge to travel through.

Power lines are dotted with large, brightly colored balls to improve the visibility of these thin wires to helicopters and small planes and help prevent potential crashes.

Colorful thunderstorm phenomena can be viewed from the International Space Station

Transient luminous events are lightning-related phenomena that occur in the atmosphere above storm clouds. These events often look like columns of red light resulting from electrical discharge, but may also appear as purple tendrils or long blue jets.

A man survived being struck by lightning seven times

Roy Sullivan worked as a park ranger when he was first struck in April 1942 while fleeing a watchtower during a thunderstorm. Nicknamed the "Spark Ranger," he would be struck six more times while driving, in his garden, working in a guardhouse, sitting in his car, walking, and on a fishing trip.

Learn about the bodies that govern the US commercial airline industry, such as the FAA

The Federal Aviation Administration (FAA) regulates US air travel, monitoring both safety and advancement. But despite deregulation in the 1970s, the industry has other governing bodies, too, including the US Department of Transportation and the TSA.

Window collisions and cats kill more birds than wind turbine farms

Researchers are developing solutions to reduce bird fatalities due to wind turbine farms, including radar systems integrating AI to detect birds and shut down systems. Painting blades with various patterns is also being tested, which may reduce bird strikes by 70%.

Examining the causes of power outages, from system damage to preventative measures

Stray balloons, contact with trees, malfunctioning equipment, and severe weather are among the causes of failures that can cause widespread, unplanned blackouts. Although contingency options that rely on alternative transmission pathways to deliver electricity from generators to consumers may be possible, some shutoffs, brownouts—available power is reduced—and cycles of repeated outages may be intentionally implemented to protect public safety.

Pyrodrones combine fireworks with millisecond-accurate drone choreography

Drones are outfitted with fireworks and positioned using 3D software to ensure perfect timing and safe spacing during shows. A single GPS error during planning can ruin the show, as happened in 2024 when a drone crashed and injured a spectator due to programming failures.

Differences in air pressure above and below an airplane's wing allow it to fly

The bending of air around a surface causes it to flow more quickly, reducing the pressure exerted by the airflow. In a commercial airplane, the pressure difference between air diverted above the wing and air flowing undiverted below it creates enough lift to overcome gravity.

Chaos theory—informally known as the butterfly effect—is the reason why weather forecasts are presented with probabilities rather than certainties.

Dirty lightning is a thunderstorm created from friction between rising and falling flows of ash and smoke during volcanic eruptions.

During flights, cell phones can act like signal jammers as they search for service

When farther from cell towers, these devices expend more energy to emit more powerful signals, which can overwhelm any ground-based tower or radio telescope they fly past. Rather than protecting the flight, airplane mode conserves a cell phone's battery.

Randomly boarding passengers onto a plane is often faster than using boarding groups

Although boarding back to front or windows to aisles appear to be sensible approaches to quickly filling a plane, these methods still suffer from passengers stowing away their luggage, which too often halts the boarding flow. Research has shown that the ideal process, called the Steffen method, optimized efficiency by allowing boarding to continue even while stowing is underway.

A Tesla Model X collided with stopped emergency vehicles on a Texas highway when flashing lights created hazy images that the software could not interpret. The crash injured five people and hospitalized another person while highlighting the challenges of autonomous systems.

Discover the catastrophic consequences of a failure of the US electrical grid—something that is more likely than many Americans think.

The attack at Pearl Harbor led to the world's first around-the-world commercial flight

A World War II-era commercial flight was forced to change course when Pearl Harbor was bombed, leading the 12-member crew on the world's first commercial flight to circumnavigate the globe. The Boeing 314 crossed the equator four times during the journey, which totaled more than 30,000 miles and required the crew to strip the plane of any identifying marks.
