Things you probably don't want to read in a note on an airplane: "I'll set this plane on fire." That's what was scrawled in pencil on a napkin found by a woman on an Egypt Air flight from Cairo to New York, and it was considered threatening enough that the plane was diverted to Glasgow, with an escort of fighter jets, the BBC reports. After three hours, the 326 passengers were finally allowed to disembark—but every single one still has to be interviewed by police.
"It almost looked like a child's handwriting or someone who has very sloppy handwriting, but it was very alarming especially these days when everyone is so concerned about safety on flights," said the woman who found the note; she's also a BBC producer. She said the mood on board became tense and "very scary." Scottish police confirm a suspicious note was found on board, but will not speculate on whether it was a credible threat.
