The BEA observed -
- The aircraft was probably intact on impact.
- The aircraft struck the surface of the water with a positive attitude, a low bank and a high rate of descent.
- There was no depressurisation.
They also mentioned that there was a left-right symmetry of compression damage throughout the length of the aircraft. For that reason, I feel that their description of "positive attitude" didn't imply anything dramatic, and I opted for +5 degrees. Also, if the airframe had ruptured abaft the main wing with a high forward velocity, the chances of the symmetrical bottom up compression damage to the forward section would be remote. I believe that a "cartwheel" type of breakup would then have occurred.
As usual, I could be wrong, and your suggestion is well worth a look.
