How can a commercial airplane survive a lightning strike carrying 200,000 amps of electricity without losing control or igniting its fuel tanks? This video explains the engineering behind aircraft lightning protection, including why airplanes often trigger lightning strikes themselves and how modern passenger jets safely conduct electrical currents through their structures.
Explore how aluminum fuselages act as Faraday cages, why carbon-fiber aircraft like the Boeing 787 require embedded copper foil, and how swept lightning strokes, protective coatings, and electromagnetic shielding protect the airframe and flight-control electronics. The video also examines onboard fuel tank inerting systems (OBIGGS), which use nitrogen-enriched air to reduce oxygen concentrations and prevent fuel vapor ignition.
Historical examples include the 1963 Pan Am Flight 214 disaster, the 1996 TWA Flight 800 fuel tank explosion, and NASA's F-106B lightning research program. Learn how aircraft manufacturers test lightning resistance using simulated electrical strikes and specialized certification procedures.
