Just saw this for the first time on a flight from Chicago to Minneapolis.

My Brazilian Embaer 175 had a “Turn Off Electronic Devices” light instead of no smoking, which is brilliant. In looking into the details a little further, it appears that they could only safely make this change as late as 1989 for flights under 2 hours, 1990 for under 6 hours and 2000 for all flights (in the US). I had no idea you could have flown a plane as late as 1989 with someone right next to you smoking away. Next it’s going to be the rise and fall of cell phones on planes…
