And enough time goes by without nobody ever seeing a cigarette being smoked midair, the fear of unknown grows (="that isn't normal, what could happen if someone lights a cigarette in an airplane, it could bring the whole plane down!") and then someone freaks out for seeing a pack of cigarettes in someone's pocket, and a few years after that the TSA will require cigarette packs to be removed at the security and kiosks in lounges to only sell cigarettes in sealed containers that must not be opened prior the flight. And after that, if there's still someone who dares to smuggle these terrorist cancer sticks onto a plane and lights one, he will bring the whole plane down because some FAA rule from 2020 requires immediate landing in that case to the nearest strip to ensure the safety of passengers. All that, despite the fact that there's still that ashtray in the toilet, non-optionally.
