On Monday morning, an American Airlines flight from Columbus to Boston was diverted to Pittsburgh International Airport after a possible lightning strike shortly after take off. The aircraft landed safely, with no injuries reported. While such incidents may sound alarming, planes are designed to withstand lightning strikes without compromising passenger safety.
What Happens When Lightning Strikes a Plane?
Aircraft are constructed with safety measures to handle lightning strikes, which typically occur once every 1,000 flight hours for commercial planes. The aluminum shell and composite materials act as a conductor, allowing the electrical current to travel harmlessly across the exterior and exit through a different point. Sensitive onboard systems are shielded to prevent electrical interference.
When lightning strikes, passengers may notice a flash or hear a faint noise, but the experience is usually uneventful. However, as a precaution, pilots may choose to divert the flight to ensure no structural damage occurred. After landing, the plane undergoes an inspection before being cleared for future flights.
Why Are Flights Diverted?
Diverting a flight after a potential lightning strike is a standard precaution. Ground crews perform detailed checks to confirm the integrity of the aircraft, even though lightning-related damage is rare. Ensuring passenger safety remains the top priority, as in the case of American Airlines flight 4642.
Planes are remarkably resilient to lightning, making air travel one of the safest modes of transportation. While a strike might cause temporary delays, passengers can trust the rigorous protocols in place to keep them safe.
