When a plane is struck by lightning, passengers typically experience a sudden and noticeable event marked by a combination of sensory phenomena. It can feel like a distinct jolt, often accompanied by visual and auditory effects within the cabin.
The Immediate Sensation During a Lightning Strike
Passengers on an aircraft struck by lightning will often observe or sense the following:
- Radiant Light: There can be a sudden, bright flash of light, visible outside the windows or even momentarily illuminating the cabin. This is the direct visual evidence of the electrical discharge.
- Strong Rumble: A loud, sharp noise, often described as a strong rumble or bang, might be heard. This sound is generated by the rapid expansion of air due to the intense heat of the lightning channel.
- Shakes: The aircraft may experience noticeable shakes or a jolt, caused by the sudden impact and the passage of the electrical current through the aircraft's structure. While startling, modern aircraft are designed to withstand such occurrences.
How Often Do Lightning Strikes Occur?
Contrary to common belief, lightning strikes on aircraft are not extremely rare events. Researches indicate that every aircraft is struck by lightning once a year on average. This frequency highlights that it's a relatively common occurrence in aviation, and aircraft are specifically engineered to safely handle these strikes.
What Should Passengers Do?
Although a lightning strike can be startling, it's crucial for passengers to remember that aircraft are built with advanced protective systems to channel lightning safely over the fuselage and wings. In the rare event of a lightning strike, passengers should:
- Remain calm: Panicking can increase discomfort and is unnecessary given the safety measures in place.
- Follow flight attendant's instructions: Cabin crew are trained to handle such situations and will provide any necessary guidance or reassurance.
Modern aviation design incorporates features like conductive materials, lightning diverters, and robust electrical systems to ensure that the lightning current passes through the aircraft without causing significant damage or posing a danger to those onboard.
