Yes - I saw Brenden's graphic movie and cetainly understand the alternative scenario. The only aspect of the incident that doesn't gel with what you are putting to me is the fact that the serious injuries and cabin ceiling penetration were apparently confined to the aft section of the rear cabin rather than randomly across all parts of the cabin.
If you could help me understand what would cause that focal point on your theory that would assist me. Maybe it's just the natural place for the majority of unrestrained people to congregate waiting for the toilet etc and my assumption that it reflects the forces at work is wrong.
