The question was really about electronic devices during takeoff and landing. They were very conservative, though I can't really fault them for it--however annoying it was to both passengers and flight crews. But given the number of electronic devices--including phones--that you know weren't actually turned off or put into airplane mode, it became pretty obvious that there wasn't a systematic problem with having devices on.
100,000 flights per day. 200 people per flight making cell phone calls? How many potential avionics issues are we talking about?
What's the most years we've gone without a major airline accident? Wasn't there a 10 year period at one point?
