Question It seems to me that all focus on passenger planes seems to be on fuel efficiency, yet it seems that almost every airliner crash results in 100% fatalities. Is there any focus right now on redesigning planes so that even if one crashes from high altitude those on board have a better chance to survive?
Answer Over the years many improvements have been made in making passenger compartments less flammable and reducing engine fire risk. Propulsion and control system reliability are always an important consideration. Beyond that it is very difficult to make an aircraft crash safe because by their very nature aircraft have to be lightweight. Weight equates to drag, fuel consumption and range reduction. Additionally, rapid deceleration kills people no matter how well they are protected from impact.
