If 20 more were injured then the seatbelt sign probably wasn't on, which means they probably hit clear air turbulence in cruise. Usually the planes ahead will report anything like that so the ones behind it will know what's coming, but this must've been a big bit of windshear one out of nowhere.
Lol they clearly asked him what he personally experienced. I'm sure the dude would have started with "what happened to others on the flight is terrible" or similar
This new flyer left his half filled coffee cup in the seat pocket and it got on my sweater on the way out, I had to wear a stink sweater with old coffee on my chest for the next 12 hours. I feel your pain Andrew from London
