Semi-related story: I started a flight from a not-1st world country to another not-1st in the times when all cell phones had to be switched off. When we approached landing, the cellphones got contact and started buzzing and ringing with incoming messages. Apparently a lot of people had ignored the order to turn off the phone. I realized that in my 1st world, people follow those orders, in other countries they just don‘t. If cell phones posed a danger to flight safety, somewhere a plane should have crashed already. Similar to here.
