I wonder if there's any video of the actual pitch pole. From the article, Andrew was the tactician, which I guess would mean he would be at the back of the boat, probably wearing some type of tether or harness. If the boat went deep bows down, he'd be wayyy up in the air, either tossed from up high with the boat landing on him, or tied to the wrong side of the boat as it went upside down.

And as mentioned, he may have been unconscious when he went into the water. I guess we'll hear from the survivors as to what happened to Andrew, eventually.
