Reports are coming out now that one of the F/O's was still alive for 40 minutes after the accident but rescue-workers were unable to free him due to... The SECURITY DOOR.
On B737, the window next to the F/O (R2) can be opened from the outside. However, this mechanism is known to malfunction when under severe stress (as certainly happened in this case) and not all emergency teams are aware of the fact.
Erickthepilot, condolences with the loss of your collegues, we are all collegues in the aviation world actually and should act accordingly.
