Next time you see your friend, ask him what happened when he woke up. It's all a pile of b*****t .
Something with this magnitude cannot be hidden from the public. Why on earth are they going to enter a holding pattern for 30 minutes in Qatar, which the plane should be nowhere near at, given that the routing is DXB - KUL, and after pointlessly holding for 30 minutes, return to DXB where they announce full emergency, crash land more or less, and eventually expect no one to notice.
If something like this were to happen, the plane would be in no condition to fly. You do realize no one can shut so many people up. Passengers, crew, ATC, people involved in the maintenance of the aircraft, people working within flight ops.. It's all a bunch of lies, the purpose of which is to badmouth EK.
