Out of context. I am not talking about damage below the forecastle deck with the Key bridge landing on it.
We do not know the structural details of the Key bridge pillar below the waterline. Possible the side shell contacted the concrete pillar before the bulwark contacted the bridge support structure above the water line.
On the video we see what looks like a bounce to the left seconds before the contact above the waterline and the bridge falling. Possible of course there is aggregate, small rocks and mud surrounding the pillar and side shell scraped this.
