I recently saw a video from Valk Aviation (actual scene) of a KLM B777-300 struck by lightning on departure. It happened a few days ago.
I know this looks more frightening than it really is and the aircraft usually isn't harmed. There are numerous posts here covering this.
But I wonder what a passenger would notice when the aircraft gets hit? Is there some kind of BANG or something? Do the lights flicker, for example?
Terrys answer implies you cannot tell for sure so I guess you won't notice at all. Is that true?
