As you view this, a couple of points: Note everyone backing away after the lightning bolt hits the tail. Of course, that is too late. Passenger airlines’ weather monitoring has deteriorated in recent years even as weather science’s ability to warn of this type of incident has improved.
Second, if you are in an aircraft struck by lighting, you’ll be fine. They are designed to withstand lightning strikes. I was on a 737 enroute from Los Angeles to Denver and we were struck with no problems.
