My friend was on that flight. I'll try to find out the truth.
As a passenger or crew?
It would be very interesting to hear what exactly the passengers was told. I understand that there is often quite a gap between cabin announcements and the actual truth. I mean, you don't want to upset the passengers by telling them that there's not enough fuel on board.
They need to fit heart rate monitors on pilots and hook it up to the black-box; that would be interesting.
