this never used to happen
It happened on a flight from London, England to the Canary Island of Lanzarote. I didn't notice the behaviour on takeoff. Perhaps I was too distracted. On the way down in Lanzarote I noticed people didn't only not turn off their devices, the guy next to me didn't go on airplane mode either. There was the generic 'turn off your electronics' announcement, but the flight attendant that came around to ensure we had our seatbelts on didn't seem too bothered by the fact that this guy appeared to be on Facebook! Then I looked out the window, and there it was; another airplane! Right there! Almost next to us. It was a little disturbing, but I trusted the pilots knew what they were doing. I hoped rather. It goes without saying that nothing catastrophic happened - quite the opposite actually. A smoother than normal landing, yes, with people listening to music, checking Facebook and so on. I'm not sure when it happened, but someone flipped a switch...
