Then why did go at length to portray the supposed disappearance of nine crew members as being suspicious, instead of being a "cock up"? You've suddenly done an about face and are now merely dismissing it as a clerical error when it was all skulduggery and potential acts of sabotage by the crew very recently according to you (you clearly insinuated that the crew knew about what was going on early in the disaster when they somehow shouldn't have and that this was definitely suspicious, as was nine of them disappearing).
This "clerical error" idea isn't your default about the supposed disappearing crew, it's a new idea you've latched onto because your new ad hoc theory about a British submarine (or whatever) escorting the ship (for some reason) accidentally hitting it (above water somehow) and sinking the Estonia doesn't require any cloak and dagger involvement of the crew, you've just just ********** that idea.
