My apologies for the Twitter link. Appears to have happened around 1:30 EDT, judging from the timestamp in the video. Seems unsurprising that Amerikkkan infrastructure is in this dire of a state (at the cost of innocent people's lives, as usual), but I'd still love to know what the hell happened here. Hopefully the early hour meant that more people weren't harmed.
Prior to the ship hitting the support column, you can see it lose power, then regain power, then thick smoke starts billowing out the top, then it loses power again, and regains power again seconds before contact.
Could the bridge have been engineered to be strong enough to survive an impact by a >100k ton ship? Maybe, but it seems like better backup and emergency systems on these huge ships might be a more practical idea. Obviously we are still very light on information.
Yeah, they're called dolphins They can be seen in the video near power pylons. However none were deemed necessary to protect the bridge itself apparently.
