If you have a Samsung phone, leave it home. The Transportation Department is issuing an emergency order banning passengers and flight crews from bringing Samsung Galaxy Note7 smartphones on airline flights. This is in response to reports of the phones catching fire. It says the phone may not be carried on board or packed in checked bags on flights to and from the United States or within the country. Samsung recalled more than 2.5 million of the smartphones and discontinued the product earlier this week. Numerous fires have been reported, including one on a Southwest Airlines flight earlier this month.
