Theres an old conspiracy theory, pre smart phone, that it was about preventing terrorists using phones as missile guidance. Basically, if you see a cellphone jumping 1 tower to the next, you can tell speed by distance and time between towers’ coverage areas.
They didnt want phones on planes creating constant false positives theyd have to verify against flight logs, etc, and obviously didnt want to give enemies ideas ideas, hence the line about interference, but of interference were a likely hazard, theyd be locking up phones for the flight.














When I was a kid, my parents had a dog that was already getting up there in years, named Arthur. At some point it was explained to me that he was moving slowly and getting tired more quickly because of his arthritis.
I thought my dad was saying ‘Arthur-itis,’ as a way of saying the dog was getting old and frail. I discovered my mistake when we were at my grandmother’s and I blamed her taking an hour to get ready to go out for dinner on her ‘Nana-itis’
