Remember, hc is the guy who told us that the size of the windows is more important that if the fuel cells are fire proof
So, lets consider how many passengers have died on N Sea operations from drowning as a result of difficulty in getting out following a ditching (sadly more than I care to remember)
HC is so right there but its not enough to make them big if it's obstructed like in this case.
