Francis Scott Key Bridge collapse in Baltimore...

Only if BOTH found something other than mud to grab onto but I doubt that happens. Even if it did there was still a chance the chains would rib the windlasses right out. This is looking to be a freak accident or possibly a contaminated fuel issue. (There was a report I heard earlier that a contaminated fuel issue is being looked into). I just don't see there is a pilot or captian mistake at this time.
Mud is good bottom for anchoring. I'm sure the windlass brake and pall would fail long before the windlass was torn from the deck, not to mention the flukes on the anchor. I've seen the flukes get torn off a 15 ton anchor in Singapore. The windlass is still fine on that ship. Trying to drop anchor and put out the proper scope in blackness, in an emergency is a tall order for any crew. I bet they didn't have enough chain out.
