I agree with redairborne22. Although I have not seen this documentary, it seems like it is more "theoretical" with a lack of eyewitness evidence.

I would also think that passengers would remember hopping or jumping over an open expansion joint (or remember people falling into them maybe).

Also, as I posted earlier, it would be nice to hear from other experts on Olympic, which I tend to believe survived storms where she achieved angles of 10 degrees down by the head (I mean, the ship was hit by a rouge wave once I think).
