School opens 'investigation' after airline kicks students off plane

I find this a good thread to clear up some issues (since the FAA won't). First, electronic devices can "possibly" (don't quote me, but the interference possibilities are minimal; but slightly probable) cause issues with an aircraft's avionics; but not likely in modern aircraft.

Second, it isn't this factor though as to why the first 15 minutes and last 15 minutes of flight such devices are requested to be turned off. Those two moments are the critical phases of flight. The aircraft is moving slower and closer to the ground. In the event of an emergency, do you want a dozen kids tweeting how they are going to die or crash or people aware of the situation?
