This is a pretty cool short (literal) film from 1987 showing a leisurely drive over the original whilst we hear stories and impressions from the toll collectors, of the time.
Definitely not an overproduced presentation -- it's just right:

Back of the napkin calculation says the MV Dali struck the Francis Scott Key Bridge with a force somewhere around ~469 meganewtons.

Numbers I started with are 114,000 tons loaded and 8 knots coming to a halt in 1 second.

If you want some comparisons for the force of the MV Dali hitting the Francis Scott Key bridge:

38 Space Shuttle solid rocket boosters at liftoff.

1/11 of the force exerted by water on the Hoover Dam's walls.

4/5th of the total force of incident photons from sunlight on the planet Earth.

CNN: NTSB has released a #timeline for the #FrancisScottKeyBridge disaster in #Baltimore based on their recovery of the voyage data recorder


It was actually only 2 minutes between notification of the Maryland Transportation Authority and the bridge collapse. Really amazing that they were able to stop bridge traffic that quickly.

I guess conservatives aren't going to be mad at Biden for the workers deaths on the since they were all from Mexico and Central America.

Current mood. Prayers to the families of the workers on the bridge when the ship hit.

Good morning and happy Wednesday.

It's been a week already.

The Key Bridge collapse hit me emotionally in a way I did not expect. It's a huge physical landmark that has been a part of my life for my entire time living in the Baltimore area (i.e. since 2008). It was a huge part of my commute and even visiting family. And now it's just...gone.

I heard a friend online say it's like grieving the loss of a human member of the community and, while it feels weird, it's kind of apt.

Still feels surreal. Still praying for those who were harmed in the incident.

Six people missing after Baltimore's Key Bridge collapse presumed dead
https://nationalpost.com/news/world/baltimore-key-bridge-collapse

Good level of detail in this article, produced by the .

"From 1960 to 2015, there were 35 major bridge collapses worldwide due to ship or barge collisions"

Well, I wonder if there will be an effort now to increase pier protection for major bridges around the world. Certainly there's a heavy cost for blocking the Port of ...

Two ship pilots were on board the large cargo vessel that hit Baltimore's Francis Scott Key Bridge.

Here’s a Q&A with a veteran ship captain, now working for a maritime academy, describing the role these pilots play on boats and why what happened last night was "absolutely" every crew member's nightmare:

Before/After satellite imagery of the in from Planet's SkySat

gives added perspective regarding the size of the cargo ship relative to the bridge.

satellite imagery of the same bridge now, with the truss lying haphazardly in the water and a large container ship at one of the supports.

I kind of get where most of the people scoffing at the idea of the feds promising to pay for the before talking about Maersk’s liability are coming from, but saying “we are going to take responsibility for fixing the problem” before any other considerations is exactly the right thing to do here.

Figuring out exactly what went wrong, who’s at fault, and to the tune of how much $$$ is going to take a while but cleanup and reconstruction has to start now.

At 01:24:30 the lights went out.

Right after that, the ship's course changed direction, heading towards the bridge.

It looks like the captain tried to change course when the lights and the engine regained power.

But 100,000 tons of mass has a lot of momentum.

What I want to know about the collapse in is why weren’t there tugboats guiding the ship under the bridge? Was it budget cuts? Are tugboats no longer a thing?

News about the that happed at 1:30 AM EST from the BBC, updated as news comes in. So far, 2 people rescued, 6 still missing, they were construction workers fixing potholes. One is in the hospital. The ship issued a Mayday before the collision, which stopped cars from coming on the bridge and saved lives. The cargo vessel lost power just before collision. FBI says it was not a terrorist attack. https://www.bbc.com/news/live/world-us-canada-68663071
