Why doesn't the planes crash during the thunderstorms??
At first glance you might think that this flies in the face of the basic safety rule: when thunder roars go indoors.
In other words, when you’re on the ground, you should take shelter in a building with plumbing and electrical wiring. You’re also safe in a metal vehicle with the windows rolled up, as long as you don’t touch any metal, such as the shift lever. Here, lightning flows through the vehicle’s outside metal and jumps to the ground.
A plane’s outer skin does the same job as a metal vehicle on the ground. Lightning hits one part of the airplane, follows the outer surface of the frame and jumps back into the air, possibly leaving small burn marks where it enters and leaves.
