Bridge Collapse in Baltimore

[Instabroke]

It's not a silly question but I would guess that it would take a significant amount of time to organise dropping an anchor for a 110,000 ton (101,605,000 kg) ship already travelling at 8 knots (4 metres per second) and it sounds like they didn't have much time BUT a few back of an envelope calculations....

The ship's momentum (mass x velocity) was 400,000,000 kg/metres/per sec. For an idea of the equivalent force to stop the ship, it would be the same as trying to stop a 737 airline that weighs 40,000 kg (2500 times lighter than the ship) going 2500 times faster than that ship (roughly 36,000 km/h).

There's no anchor and steel chain in the world that could bring that ship to a stop without snapping instantly if it got stuck in something or with it's weight it would take hours for it to slow down. A ship has to be stopped to put an anchor down.

Very interesting, thanks for that.

6 dead all migrants filling in potholes on the bridge.A job the yanks would not do. No migrants = bigger potholes.

I don't think potholes will be the problem for that bridge for quite some time.

hope the company that own the ship have a good insurance policy

it’s hard to believe this took five pages to be done.

Comprehensive reply. Cheers

Getting a ride??

This was quite clearly a case of the ship losing power, but no doubt the yanks will want to blame someone. I wouldn't be surprised if the pilot gets thrown under the bus

You can see the moment the lights go out here -

Thanks for the reply Beanee
It appears from the press conference on the recording from the black box
that the pilot requested the port anchor be dropped 2 minutes before collision
