Is it safe to be in an airplane during a lightning storm?

Lightning can strike a plane when travelling through or near a storm, however, you'll still remain safe when in the air. The aircraft are designed to withstand lightning strikes and the electric current travels alongside the aluminium frame.



Yes, it is extremely safe to be inside an airplane during a lightning storm. Modern commercial aircraft are engineered to act as a Faraday cage; when lightning strikes, the electrical discharge travels along the exterior aluminum or composite skin of the fuselage and exits through the wingtips or tail, leaving the passengers and sensitive electronic systems inside completely unharmed. Statistically, every commercial airliner is struck by lightning about once a year (or every 1,000 flying hours). While you might hear a loud "bang" or see a bright flash that can be startling, it is rarely a safety concern. Pilots use high-tech weather radar to avoid the most severe cells of a storm, primarily to avoid the extreme turbulence associated with them, rather than the lightning itself. In 2026, aircraft also feature "static wicks"—small wires on the trailing edges of the wings—that help dissipate static electricity back into the atmosphere, ensuring that nature's electric displays remain nothing more than a spectacular show for those watching from a safe, pressurized cabin.

In fact, the National Weather Service says passenger planes are struck by lightning an average of once or twice every year. But the last confirmed commercial airplane crash in the United States attributed to lightning occurred in 1967.

Do Flights Get Cancelled Due to Thunderstorms? Yes, this can happen. In fact, many flights are cancelled regularly around the world due to thunderstorms making it dangerous or impossible to take off.

How many planes have crashed due to lightning? NTSB recorded 40 lightning-related aircraft accidents.

MORE DETAILS

It's almost always a combination of factors that lead to an accident. Whilst flying is extremely safe, the typical reasons as to why planes crash include pilot error, technical failures, bad weather, terrorism, and pilot fatigue. There is never one single cause attributed to pilot an aircraft crash.

MORE DETAILS

Turbulence, associated with thunderstorms, can be extremely hazardous, having the potential to cause overstressing of the aircraft or loss of control. Thunderstorm vertical currents may be strong enough to displace an aircraft up or down vertically as much as 2000 to 6000 feet.

MORE DETAILS

The most likely time of a crash is during takeoff or a landing. When pilots and flight crews are aware of these dangers and how to combat possible issues and hazards the chances of an accident decrease.

MORE DETAILS

Since the mid-90s, due to advances in technology and training, the U.S. has not experienced a thunderstorm-caused accident. Yes, thunderstorms can cause an accident, but we have mitigated the risk to be very, very low.

d. Hail. (1) Hail competes with turbulence as the greatest thunderstorm hazard to aircraft. Supercooled drops above the freezing level begin to freeze.

MORE DETAILS

Although passengers and crew may see a flash and hear a loud noise if lightning strikes their plane, nothing serious should happen because of the careful lightning protection engineered into the aircraft and its sensitive components. Initially, the lightning will attach to an extremity such as the nose or wing tip.

MORE DETAILS

The inner pane basically safeguards the load from the passengers during flight. When both the outer and middle panes break, then all the pressurization in the airplane would escape leading to decompression in the passenger cabin. A plane is pressurized for passengers' comfort as it climbs to a higher altitude.

Reduced visibility, associated with cloud, mist, fog, or sand storms, can make safe flight difficult or even impossible, even with the help of technology (Instrument Landing System (ILS), weather radar, synthetic vision systems, etc)

MORE DETAILS

With this in mind, horizontal winds (also known as “crosswinds”) in excess of 30-35 kts (about 34-40 mph) are generally prohibitive of take-off and landing.

MORE DETAILS

Airplanes are designed to withstand lightning strikes, which are a common occurrence during flight. The fuselage and wings of an aircraft are designed to dissipate the electrical energy from a lightning strike, protecting the passengers and crew inside.

MORE DETAILS

This happens because an aircraft's fuselage, or body, acts as a Faraday cage (a container that blocks electromagnetic fields). Energy and electric charge from the lightning bolt run around the outside of the vessel, protecting the interior from any voltage.

MORE DETAILS

Winter has strong winds and blizzards, and summer's hot heat can create unstable air, thunderstorms, and tropical storms. That means flying during the holidays often means more turbulence than other times of the year. So if possible, avoid flying between December and February or June and August for a smoother flight.
