Though most of us know that lightning bolts striking planes aren't too much to worry about these days, seeing the actual bolt go through the plane is always a frightening sight. There are hundreds of people in that flying tube! And they're getting zapped by lightning! Of course, there probably unaware of it and it's only us on the ground who see the terrifying image.
This is what a lightning strike on a plane would look like from the ground. Reddit user PJCommisioner's friend took a random picture of the London sky and ended up capturing the exact moment the bolt struck the plane. You can see the bolt actually travel through the plane, as the plane acts as a conductor, and continue on its zippy way. Completely random. Completely terrifying. [Reddit]
