I have to agree with Andraz above. I did a Israeli charter from London a few years back with a plane full of people off for a religious celebration. Unruly is an understatement, but not in the drunk lout way that is usual for British pax. These families just totally ignored everything anyone said, they were also incredibly nervous about flying, lots of prayers, and I have never been blessed so many times before and after departure. It was a very interesting day out, and I'm wouldn't be remotely surprised if there was mass panic at the first sign of smoke.
