was there panic in the cabin etc etc.?
Lawyers and experts of those who have to pay for this accident (in excess of the damages provided by international conventions) will try to show that the passengers did not suffer (did not know they were going to die)
Lawyers and experts of families will try to prove otherwise because if passengers knew they were going to die ... this will increase the amount to be paid to families
So .. for have an answer to your question .. you must wait the end of the judicial process
