Very sad.

The plane simply dissapeared. I can only imagine what the relatives of the victims must've gone through. There was never a 'sorry, your loved ones have died in a plane crash'. Only a 'sorry, they're missing. We don't know were they are. If we don't hear from them before 13:00, we must assume they're dead'.

At 13:00, the fuel would ran out. It must've been agonising. In matters of death, people will hope against hope. Usually in vain.
