The Federal Aviation Administration’s official site:
In light of recent incidents and concerns raised by Samsung about its Galaxy Note 7 devices, the Federal Aviation Administration strongly advises passengers not to turn on or charge these devices on board aircraft and not to stow them in any checked baggage.
In my lifetime, I cannot think of a time when a specific product was called out in this way. As in, we urge you not to even pack this specific product in your luggage.
I can’t imagine what the Samsung corporate folks are going through right now. Airlines are banning the phone, there are stories of car fires. This is truly terrible.
