While there may not be a mystery as to WHAT happened, what are the possible ramifications of this event? What is the potential for more significant damage to the aircraft and its occupants?
And how should this event have been handled by the crew? Passengers describe a significant sound attached to this event. Was the cockpit crew aware that something had happened? Someone in the cabin crew must have heard the noise as well. One would assume that the cockpit was notified.. The event occurred 30-45 minutes after takeoff, so close to cruising altitude.
If the cockpit could have seen the damage to the aircraft, I assume that they would have returned to DXB at that point in the flight.
