The US air traffic control system is safe but due for major technological updates

Is there a shortage of air traffic controllers?

In 2024, the Federal Aviation Administration employed more than 14,000 air traffic controllers—crucial workers who direct traffic in and out of airports and around legal airspace. However, due to long training programs and the pandemic's aftereffects, as of 2023, nearly half of the agency's 290 facilities are understaffed. The agency has attempted to shift its hiring direction to increase its numbers.

The aviation industry built trust in automation by keeping pilots in the cockpit

Nearly 70% of Americans feel uncomfortable riding in a driverless car, and 81% of them would not fly on a pilotless plane. However, automated systems on planes were slowly introduced and advertised as enhancing safety—an approach that may benefit driverless vehicles.

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.

This piece explains why commercial aircraft rarely crash in thunderstorms, detailing how pilots use onboard radar, shared reports, and strict avoidance protocols to navigate storms that look far more dangerous on screen than in reality.

The turbulence experienced in airplanes results from unexpected changes in airflow

Pilots rely on forecasts, onboard tools, and air traffic control to avoid regions of severe turbulence during flight. Turbulence is generally weaker for those sitting in the front of the main cabin and for morning flights that follow cooler nighttime temperatures.

44 states in the US have implemented ride safety laws

Rides are developed and tested for years before they host passengers. Maintenance teams perform various tests every day before opening coasters to the public. The chances of risk are rare, as exemplified in 2019 when amusement parks saw .8 injuries per million rides.

Two main types of inflight WiFi connections are air-to-ground and satellite-based

ATG systems rely on aircraft antennae to catch signals from cellphone towers, while the latter uses a network of satellites transmitting data from space. As of 2022, airlines like Delta and United hosted over 1.5 million monthly WiFi sessions.

By 2030, experts estimate a 1 in 1000 chance of a plane being hit by space debris

As more satellites and spacecraft are launched, the rate of space debris re-entering Earth's atmosphere, including those that do not burn up completely, increases. International space agencies and air traffic control systems will need to coordinate to develop standardized methods and technical solutions to prevent and minimize future crisis scenarios.

Rising satellite numbers pose increased risks of planes being hit by falling debris

Projections of more than 100,000 satellites in space by the 2030s—eight times the number in 2025—highlight a growing threat to aviation. Experts suggest the odds could reach seven in 10,000 annually by 2035, alongside higher risks to people on the ground.

In 2021 alone, there were over 1,000 reported derailments in the US—and no amount of maneuvering will reduce those numbers to zero. This 101 explains the causes of train derailments and how safety protocols look to limit them each 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.
