Working backwards...
Some of the survivors worked their way along the port side of the ship to get down to the water AND USED THE OPEN RAMP TO CLIMB DOWN. So you have three or four people right there who could give immediate testimony.
The bangs were the bow cover clamps failing. The scraping sound was the bow cover scraping the hull as the ship plowed over it.
Yes, I have had things fall off a shelf due to a slamming door. I have also experienced a 6.9 earthquake. Neither of this things is comparable to being on a large steel ship in rough seas.
The JAIC very clearly states the bow ramp was closed.
I think we all know what clunking metal sounds like and can differentiate it from explosions.
