Search in Flight Mechanik Forums the Aircraft had Antenna socket Problems
The most say:
-The antenna socket gave away
-The Cabin presure fall down
-Pilots try to turn Back
-Pilots falled asleep cause of no Oxygen
-Passengers falled asleep after 12 minutes
-Cabin crew with Oxygen Bottles falled 20 minutes after Cabin pressure Asleep
-The plane travel till fuel out and fall down like a Stone.
AND JUST CAME in CNN there are no Oxygenmasks in 777 Flight Training Simulators!
They never Train puting Oxygen Masks on.
REMEMBER Flight Helios
