More worryingly, the phone in question was a replacement Galaxy
Note 7, one that was deemed to be safe by Samsung. The Verge spoke
to Brian Green, owner of the Note 7, on the phone earlier today
and he confirmed that he had picked up the new phone at an AT&T
store on September 21st. A photograph of the box shows the black
square symbol that indicates a replacement Note 7 and Green said
it had a green battery icon.
Green said that he had powered down the phone as requested by the
flight crew and put it in his pocket when it began smoking. He
dropped it on the floor of the plane and a “thick grey-green angry
smoke” was pouring out of the device. Green’s colleague went back
onto the plane to retrieve some personal belongings and said that
the phone had burned through the carpet and scorched the subfloor
of the plane.
The last line of the article is a real kicker.
