one of the pictures from Reuters.com looks a mighty lot like a fan blade, definately not the way Rolls Royce would want an engine to fail. Couldn't the damage to the wing be like this because slats where extended, so the front part of the wing was missed. There are usually hydraulic lines installed at the rear part of the slats (for obvious reasons), damage to the wing looks to be coinciding with the position of these lines, at least on aircraft types i have flown...
My two cents.
Well done to the fellow pilots who landed safely!
