No — a lightning strike is almost never dangerous to a modern plane. Aircraft are deliberately built to be struck: the metal skin acts like a Faraday cage, carrying the current around the outside and away from passengers, fuel and avionics. On average each airliner is hit roughly once a year, you may just see a flash or hear a bang, and the plane is inspected on the ground afterwards as a precaution.

Lightning hitting your plane sounds like a nightmare. In reality, it is one of the most over-feared things in aviation. Engineers expect strikes, design for them, and certify aircraft to survive far worse than a normal bolt.
So let’s walk through exactly what happens, why you’re safe, and why a thunderstorm mostly costs you time rather than safety.
Is it dangerous when lightning strikes a plane?
Almost never. On average, each commercial airliner is struck by lightning roughly once a year, and these strikes almost never cause any harm. The aircraft is built to take the hit: its conductive skin behaves like a Faraday cage, carrying the current around the outside of the fuselage and away from the people, fuel and electronics inside.
Inside the cabin, passengers usually notice nothing more than a brief flash of light and a loud bang. Any further effect — a momentary flicker of the cabin lights, or a little radio static — is rare. The strike doesn’t change how the plane flies.
The most important fact for nervous flyers: lightning has not brought down a modern commercial airliner in over half a century. The safety comes from engineering, not luck.
Why are planes designed to be struck by lightning?
Because they will be struck, so they’re built for it from day one. A strong strike can carry a current of up to around 200,000 amperes — the worst-case figure aircraft lightning protection is certified against — and lightning in general can reach about 30,000 degrees Celsius, far hotter than the surface of the Sun. The trick is to never let that energy inside.
An aircraft’s metal skin (or, on composite aircraft like the Boeing 787, a built-in copper-mesh or foil current-return network) acts like a Faraday cage. The charge stays on the outside surface. A strike usually enters at one extremity — the nose or a wingtip — and exits at another, often the tail, while the skin keeps the electrical charge away from the cabin.
Two more quiet heroes do the rest of the work:
- Static wicks (static dischargers): small pointed conductors on the trailing edges of the wings and tail that continuously bleed off the static charge a plane builds up in flight.
- Electrical bonding: all the metal parts are electrically joined together, so the current always has a continuous, predictable path to follow.
Put simply: the plane gives the lightning an easy route around the outside, and the lightning takes it.
What does a lightning strike feel like inside the cabin?
Underwhelming, which is exactly the point. Most passengers report nothing more than a sudden flash of light at the window and a sharp bang, almost like a camera flash with a thunderclap attached. Then the flight simply continues. The crew are trained for it and the aircraft systems are designed to ride it out.
Occasionally there’s a brief flicker of the cabin lights or a burst of static on the radio, but even that is uncommon. You will not feel the plane drop, lurch or lose power from the strike itself. If turbulence rattles you more than the bang, that’s normal — and it’s a separate thing entirely. Our guide to why turbulence happens and whether it’s safe covers that bumpy feeling in detail.
Has lightning ever actually brought a plane down?
Not in over half a century. The last fatal US crash attributed to lightning was Pan Am Flight 214, a Boeing 707 that crashed near Elkton, Maryland on 8 December 1963, killing all 81 people aboard (73 passengers and 8 crew). The Civil Aeronautics Board concluded that lightning ignited fuel-air vapour in the number-one reserve fuel tank.
That tragedy is precisely why flying is so safe from lightning today. After the crash, US authorities mandated static dischargers on jets within a week, and lightning and fuel-tank protection has been a built-in aircraft certification requirement ever since. Every airliner you board has been designed and tested to handle strikes — that’s the whole reason a hit is now a non-event.
One note: Pan Am 214 is US accident history, used here only as the turning point that created modern lightning-protection rules. It is not a story about Indian aviation, and nothing like it has happened to a modern jet in decades.
What happens to the plane after it gets struck?
It gets checked before it flies again. After any known or suspected lightning strike, the aircraft is taken out of service for a ground inspection. Engineers visually check the skin and extremities for burn or pit marks at the entry and exit points, and verify the communication, radar and navigation systems. If no damage is found, the aircraft is usually cleared within hours.
This inspection is standard airline and maintenance practice, with oversight from India’s aviation regulator, the DGCA. It’s the same reason a strike on the ground or in the air can add a delay to your day: the precautionary check takes priority over the schedule, every time.
| What people fear | What actually happens |
| “The plane will fall out of the sky.” | The current flows around the outside; the plane keeps flying normally. |
| “My phone might cause a crash in a storm.” | Phones and cabin electronics don’t bring planes down. Safety is engineered. |
| “A strike means an emergency landing.” | Usually just a flash and a bang, then a routine ground check later. |
| “Lightning will fry the controls.” | Avionics are shielded and bonded; effects are usually nil or a brief flicker. |
If strikes are harmless, why do storms still delay my flight?
Because thunderstorms cause far more delays than danger. Pilots and air-traffic control space out, reroute, hold or divert flights to steer around storm cells rather than fly through them. The real weather hazards are turbulence, hail and wind shear near the ground — not the lightning strike itself.
There’s also a very human reason for monsoon delays in India: during a storm, ground operations such as loading, fuelling and pushback are often paused for the safety of the tarmac staff. Lightning on the apron is a common and honest reason your flight sits at the gate.

What did the IndiGo Kolkata lightning strike show us?
It’s a textbook real-world example. IndiGo flight 6E 6068 from Kolkata to Agartala was struck by lightning while parked at the aerobridge during a monsoon storm at Kolkata’s Netaji Subhas Chandra Bose International Airport on the morning of 19 June 2026. All 141 passengers and 6 crew were unharmed, the aircraft was grounded for inspection, and a replacement aircraft completed the flight after a delay of about three and a half hours.
That sequence is the system working as designed: a strike, no harm to passengers, a precautionary ground inspection, and a swap to keep everyone moving. According to reports, three ground workers — reportedly two baggage loaders and a pushback driver — briefly suffered temporary hearing effects or shock, were hospitalised and later discharged. We attribute that detail to news reports rather than stating it as confirmed fact, as there is no DGCA release on it.
The takeaway is reassuring, not alarming: even a direct strike on a busy apron ended with everyone safe and the aircraft checked before its next flight.
What are my rights if a storm delays my flight in India?
Weather sits in a special category. Under DGCA rules, weather is treated as an extraordinary circumstance, so airlines are generally not required to pay fixed cash compensation for a storm delay. What you can still expect is care and assistance during a long wait, and a refund or rebooking if your flight is cancelled.
The exact thresholds and what’s owed depend on the length of the delay and the airline’s policy, so it’s worth knowing the framework before you travel.

Common Questions
Can lightning make a plane crash?
It is extremely unlikely. Lightning has not brought down a modern commercial airliner in over half a century. Aircraft are designed so the current flows around the outside skin, away from passengers, fuel and electronics. You may see a flash or hear a bang, but the plane keeps flying normally.
How often does lightning hit a plane?
Roughly once a year on average for each commercial airliner. Strikes are common precisely because aircraft fly through and near weather, and they almost never cause harm. The aircraft is built to be struck, so a hit is usually a non-event noticed only as a brief flash or bang inside the cabin.
Will my phone or laptop attract lightning or crash the plane in a storm?
No. Phones, cabin electronics and the strike itself do not bring a plane down. The safety comes from engineered protection — the Faraday-cage skin, static wicks and electrical bonding — not from switching devices off. Airplane mode is a separate, precautionary radio rule and has nothing to do with attracting lightning.
What does the airline do after a lightning strike?
It takes the aircraft out of service for a ground inspection before the next flight. Engineers check the skin and extremities for burn or pit marks and verify the radio, radar and navigation systems. If no damage is found, the plane is usually cleared within hours. This precaution is standard maintenance practice under DGCA oversight.
Is it safe to fly during the monsoon in India?
Generally yes, though expect more delays. Pilots and air-traffic control route around storm cells, and ground work like fuelling and pushback may pause for tarmac-staff safety during lightning. The main weather hazards are turbulence, hail and wind shear near the ground — managed routinely — rather than the lightning strike itself.
Why is the flash and bang so loud if it’s harmless?
Because lightning is genuinely powerful — a strong strike can carry up to around 200,000 amperes — but that energy travels around the outside of the fuselage, not through the cabin. The bang and flash are simply that immense discharge passing close by. The skin keeps the charge outside, so you experience the drama without the danger.
