When Zafar Masud ponders the difference between his miracle survival and the death which claimed nearly all his fellow passengers, one of the most significant reasons for his escape seems to come down to his simple preference for an aisle seat.
When Mr Masud now looks back to that fateful morning two years ago, many of his actions are loaded with significance.
His decision to take a later flight than originally planned, or the flight unusually running on time have all become important points in his survival story. But perhaps none more so than his late decision to swap from a place by the window, to seat 1C on the aisle.
“I think that in my survival that the location of that seat plays a very significant role,” Mr Masud told the Telegraph.
