Yeah, the Feds are so reliable these days.

as opposed to who, the Qanon nut-jobs conspiracy theorists on X? If you don't have any faith in the different local, state and federal authorities that will be investigating this and are already there, then you should just move somewhere else.

People are dead here. Likely undocumented people who had to work as independent contractors for some crap pay for a middle of the night pot hole repair job. These are the people who are missing. These are the people who rushed to close the bridge when warned, saving countless others.

WTAF is wrong with you?

I hope that the families of the workers that were killed are taken care of.

To the people suggesting that the bridge was shoddily designed or constructed -- that's like blaming the person who built a house if a semi truck accidentally drove through the living room window. You can't build things that are impervious to catastrophic events. Whatever failures occurred here (and there were likely several) they don't lie with the people who designed and built that bridge. And by the way, those same people will be responsible for rebuilding it, and may have known the work crew who was on the bridge and likely lost lives, so next time perhaps think a little harder before weighing in.

The ship weighed ~100,000 tons. It was moving at 9 knots so about 4.5 meters/sec. That gives it a momentum of 450,000,000 newton/sec. Momentum in a collision is largely conserved, so all that momentum was transferred to a single bridge support. I’ll let the bridge engineer tell us how big a support would need to be to withstand that amount of force/sec.

I image that if you have the windows down, the water would flood the car with such force that you couldn't fight it and it would submerge the car more quickly.

Car Safety Hammer Set of 2... https://www.amazon.com/dp/B07MK2GNKD?ref=ppx_pop_mob_ap_share

Those hammers were designed for windows with air behind them, not with a wall of water that is pressing inwards on the glass. The water pressure is going to act like a wall of concrete behind the window and keep it from moving even the tiniest bit so you have to create ALL of the force to shatter the glass from your arm projecting the hammer. That's nowhere near enough force for the new shatter-resistant glass. So, you might buy yourself a few seconds of additional time with air, but you will be trapped in the car.

Also, you can simply open the doors if they are unlocked

Same with this idea. The water pressure from the water will prevent you from pushing the door open. It will be like the car door fell against a rock or the ground. You can't push it out when there is much more force pushing the door in that you can create.

It was probably consultants who prescribed reduced maintenance of the ship to save on costs that resulted in this. It's entirely their MO like the train crash disaster in Ohio where they proposed to cut staff and maintenance to the bone.

I literally watched a West Wing episode two days ago with flashbacks to when Sam was a corporate lawyer and helped a shipping company buy a crappy ship, that ended up running aground in North Carolina and leaking.

Nerd alert here, but in that episode the ship ran aground near Rehoboth Beach, Delaware.

Crap. Stupid middle aged brain.

You either misspelled "kilograms" or didn't do the metric conversion. In the latter case, it would be 405,000,000 newtons/sec.

Not just our area. According to wikipedia (I know, I know, but good enough for anonymous message board posting) it ranks 7th out of 36 US ports for total dollar value of goods handled, handles 25% of all US coal exports, and handles everything from cars to lumber to steal.

Yep, those hammers aren’t made for water. Those hammers are made for dogs and kids trapped in hot cars.

Those hammers aren’t even guaranteed to be effective on land. The problem is that the glass automakers use has become much stronger in recent years. They’ve done tests and modern laminated and tempered windows in new cars often can’t be broken by a regular person using those tools.

I thought you are meant to open the window ?

Yeah those dinky Amazon tools stand no chance against a modern window with water behind it. l
