Yes it is true that they have done a study, Greenwich university..... but it's not even in the top 100 universities in the UK
. I have worked in an airport and know basics of aircraft automation engineering. I can tell you that this study is stupid.
From an engineering perspective, the chances of surviving an aircraft increases the closest you are to the back of the airplane. Did you know this is where the black box resides at the tail segment of the plane?
Previous crashes have most of the time shown the rear tail segment of the planes intact at the site of the crash but the passengers have died on impact but hey atleast your body will come out intact even if you die.
Here have a read about this:
In reality you will most likely die in any circumstances due to the shock of the impact. Did you know that the brace solution was longingly debated as not a safety precaution but to ensure the person dies immediately upon impact believe it or not?
Well putting this aside, the reason I also sit at the back is because the middle seat arrangement diminishes at the back and if you've got a seat on the sides ideally the aisle, you've got plenty of room on your side and the passing trolleys won't bother you at all for both airbus A340 and Boeing777.
The seats start changing around row 37-39 if you look here on the Air Mauritius planes. I think it's 46-48 on a Boeing.http://www.airmauritius.com/aboutus/a340eseatmap.pdf
Does it make sense?
