hello there
nobody didn't see anything after accident.I was there and i saw the cockpit after fire.All Technic personnel says the cost of damage to the cockpit around 15-20 million dollars.there is no cockpit there only wreck.
And yes someone from the cockpit left from the plane firstly cause engine number 2 was running and captain went to front of the engine.But all other crew left the plane last. If you have a chance to see video record one day you'll see.(or we can read accident report in the future)
All o2 masks dropped from psu its correct cause a short circuit,and evocation time was 55-60 seconds.
What was the reason for the fire i don't know but in my opinion evocation was successful.Rapid fire in the cockpit,no time for the evocation command,all electrical system gone and only 1-2 broken leg.
