Wonder
Very very stressful situation, dual engine flame out while on final above one of the most densely populated cities in the world.
One thing that I don't understand though is why after realising the engines were not responding, the crew decided to lower the flaps further down anyway. One would tend to think you would give yourself the best possible glide ratio by reducing flaps, even if it means flying 12° nose up. Just a thought though, since they probably would not have made it to the runway anyway.
