Lol my mate was on this flight and all he said BEFORE this came out was "There was a bit of bad turbulence over Greenland but nothing major"
He used to be crew so has seen it all before. He menetioned no crew member shouting we're going to crash, no-one else screaming, no-one throwing up....
I suspect it was bad turbulence but you know how the press like to tart up a story!
