I Heard that through the news that, most of the time or many times in plane crashes what kill the passengers is: The Smoke...And i was wondering why ariline planes dont have a sprinkler system (though i know that there are 2 kinds of fires, electrical & regular fires) or why dont they have fire extinguishers every 3 eindows, or why doesnt a speciall: firefighter in a special seat, who is paid personally (not a complete firefighter) paid so that when there is a collision he: putts away the smoke, and his seat belt is made out of metal with a special capsule i dont know (i know sort of cruel), what i am trying to point out is that they are not even showing effort to stop plane crashers passengers from dying...

I wonder how much a: plane crash cost an: AIRLINE....
