From The Telegraph:
"For 25 minutes, the plane steadily lost altitude until it was spluttering 10 feet above the sea.
Then I saw the wing tip clip a wave and then the whole plane cart-wheeled. There was a bang."
If the pilot had trimmed off the yaw tendancy due to the first engine failure, then had closed the second throttle in preparation for the crash, then the aircraft would have yawed the other way if he hadn't anticipated it, ( quite possible if he had be flying for 25 mins. over water, under that amount of stress ). Yaw = roll = wing tip hitting the water first. Just what you don't want. Another case maybe where 2 engines on a light twin equals twice as much trouble, instead of half as much. I'd be interested to learn which wingtip hit the water first.
