On pictures of recovering starboard side of the cockpit - is engine nacelle in pictures on the previous page from left or right engine? If it's from the left engine, and left wing already has possible missile damage, then the missile could have come down from the right, sawing off the port side of the cockpit and leaving the starboard practically untouched.
They need to reconstruct the trajectory of penetrating pieces to add any weight to this kind of speculations, though.
I mean people seems to be convinced that the missile came from directly ahead while all the damage seems to be concentrated on the port side of things.
