Why would they leave the dead bodies of the flight crew in their seats? Ive never heard of this before. It was some what chilling to see some of the emergency services peering through the windows of the flight deck looking at the dead bodies.
Also 3 crew? Training? Line check? Where all 3 people in the flight deck crew or was the person on the jump seat someone else??
This is not the case. I've seen it in at least one other incident that the Flight crew were left in the cockpit and there is photo evidence of it on the net, which is quite morbid in my opinion..They may not want to remove the bodies until investigators have given the all clear that they can be removed without damaging invaluable information from the scene itself. A single flick of one switch by a member of the emergency crew could change the whole investigation.
As already stated by a member, there is a number of reasons why there were 3 on the flight deck, Training, FO or captain getting a ride, Cabin crew.....who knows, not us thats for sure. Also, the injuries incurred would be unpleasent to say the least, ranging from Spinal compression, Massive trauma to the organs and extensive open fractures. What makes the situation worse is the fact that no emergency was declared in the cabin (apparently) resulting in further injury than normal. It's a miracle anyone has survived this to be honest. You only need to look at the Trident incident out of LHR to show these sort of impacts normally result in total loss of life.
EDIT
If you look at the High res images of the wreckage, you can see where the inner frame of the plane has become disjointed in the impact (Look through the windows and you can see how distorted the PAX area is...Although from the outside the plane looks relatively intact, it looks a very different picture inside.
