A recent article in the Wall Street Journal tells us what we already know: electronics don't really interfere with the airplane gear necessary for take-off or landing. There weren't a lot of new statistics, but just basic logic. Something we've all thought about before.
You see, the WSJ simply surveyed about 100 people asking whether they shut their phones off during take-off, etc, and just about everybody said that they did not. You probably do not. Most people probably do not. And yet, planes are not falling out of the sky all the time. Which would seem to imply that using electronics during a flight take-off is not quite as dangerous as the FAA makes it seem. But they don't plan on changing anything about these rules anytime soon.
