In all the research I did, in general, overwing exits are the ones to avoid. OF course there will always be exceptions to the rule and we should be grateful perhaps that there are over wing exits (although some previous 747-100 operators bent even these rules!!!).
In response to some of the criticsm from some posters. I could probably give the saftey demonstration verbatim from my chair and I can describe how to open just about any door. I am not the person the crew will be worried about.
In an accident where you land substantially intact, the crew (assuming they keep it together) can organise a reasonable evacuation through the most suitable doors. In a more dire situation its every person for themselves and doors/cracks in the airframe are all valid exit points.
My main points still stand. Most pax have no idea and don't care, it wont happen to them and if it does they think they will be dead.
Airlines don't really care (some try harder than others). Where are the smoke hoods, why are babies allowed on parents laps etc etc.
There never will be a safe, economic way of providing acceptable safety that people will pay for, but there are relatively cheap ways of significantly upgrading the safety that airlines just won't take.
Just as the FAA mantra goes, if planes don't crash there isn't a problem, and if there is it would not have been survivable anyway so why bother.
