There was a study this week by Greenwich University in London that studied the best chances of survivors based on your seat assignment. They studied over 105 accidents & interviewed over 2000 survivors of former plane crashes. The study concluded that the best seat for you to survive a plane crash was an aisle seat near the front within 5 seats from an exit. I am sure the study had a good purpose, but I think it gives a force sense of security. In my experience it doesn't matter much where you sit because most people who die from airplane crashes die from either the trauma due to the direct impact, or smoke inhalation. Regardless of where you sit, your odds improve of surviving if you have that mind set to survive such as paying attention to the safety briefing, or acting quickly when an emergency happens. For instance, think of the people in the World Trade Center top floor of building 2. When the first airplane hit the first tower, People had precious minutes in the other tower to make their escape. Some people listen to their intuition  & escape while others hesitated & perished.
