A lightning strike crushed the nose cone of the IndiGo jet during its descent through severe weather. The plane later landed safely in Lucknow
An IndiGo flight carrying 104 passengers and six crew members from Patna to Lucknow encountered a terrifying mid-air event when a massive atmospheric electrical discharge struck the aircraft at 17,000 feet. The lightning strike crushed the nose cone of the jet during its descent through severe weather.
Despite the visible structural damage to the front of the aircraft, the plane landed safely at Chaudhary Charan Singh International Airport ahead of schedule, with zero injuries reported. The incident highlighted the remarkable engineering principles that protect commercial aircraft from fatal electrical strikes.
Faraday Cage Principle: Why Jets Do Not Explode
Commercial airliners are built on the principles of the Faraday Cage, a continuous conductive shell that directs electrical charges along the outer skin of the fuselage. When lightning strikes a plane—delivering hundreds of millions of volts of electricity—the charge enters at an extremity, such as the nose cone or wingtip, and flows around the exterior metallic skin or embedded copper foil mesh before safely exiting through static discharger wicks located on the trailing edges.
This conductive outer layer insulates the interior cabin, protecting sensitive avionics, fuel tanks, and passengers from electrical currents.
Why the Radome Took the Main Hit
The nose cone, technically known as the radome, is the most vulnerable section of an aircraft during an airborne lightning strike. Unlike the rest of the fuselage, which uses metallic alloys or composite materials layered with conductive copper mesh, the radome must be manufactured from non-metallic fibreglass or composite materials.
This non-conductive design is essential because the weather radar dish sits directly inside the nose cone. Any metal shielding around the nose would block microwave radar signals, leaving pilots blind to storm clouds. Because the radome lacks the continuous conductive outer layer of the rest of the fuselage, a direct strike can cause significant localised thermal damage, structural crushing, or surface puncture before the electrical arc transfers to the conductive body of the aircraft.
