I’m so old I remember when we could walk onto airplanes for a transcontinental flight with no security checks at all, and then everybody chain-smoked like fiends for the whole trip.
I should add that I was one of the weirdos who didn’t smoke.
Maintenance crews used to find leaks in the aircraft fuselage by looking for the yellow streaks left by all the nicotine escaping from the pressurized smoke-filled cabin.
