They're not disappearing "in mid air". They're disappearing exactly at joints in the bridge struts, just the kind of place where they might have had nests. (Watch it at 1/4 speed to see this.) But it may well have been faked, as they look rather large in relationship to the bridge. I don't know what kinds of birds are found around that area.
There are also worries among the conspiracy minded as states and cities prepare to deal with the huge influx of people, and the possible disruptions to traffic, cell phone systems, and the like. Having been in SC for the last American total eclipse, and seen the traffic across a state grind to a halt for hours after the Big Event, such planning seems just prudent to me...
The total eclipse will happen on April 8, visible from Texas to Ohio (and including my house in that region, so I will be having out of state guests). It would seem that some religious "end-times" preachers are having a fit about it.
I was under the impression that it's the groundhog that's afraid of shadows, not geological fault lines!
The priest in LadyHawk was quite happy about the coming eclipse.
I thought that they were pelicans, before realizing that I'd set the speed on the vid to 1/4, so they were appearing to be doing the "big ol' pelican slow wing flap." At normal speed, they appear to be flapping like smaller birds, meaning they are either well in the foreground, not really near the bridge, or have been added so that they can magically disappear.
They look like some type of cormorants (large black bird near water) to me (as a bird watcher and photographer)
In reality, rudders work better the faster water is traveling over them. For example, say a boat is going 5kts. There is a certain amount of water going over the rudder due to the 5kt speed plus the push of the water from the propellers. That is why it is prudent for me on my boat to slow down prior to engaging in a turn or entering into potentially hazardous areas as a later increase in speed will have an increased propeller effect (turning sharper in less space) on the turn. If, as in the case of MV Dali the captain orders the engines to reverse, the ship will lose rudder efficiency as the propeller effect is eliminated and the ship starts to slow further reducing water flow over the rudder. Plus "propeller walk" can cause the stern to move right or left on single screwed ships depending on the rotation direction of the propeller. My boat (an Island Packet 31) will walk the stern to port on reverse.
You're right, with a large bird. I've seen bank swallows zip into a hole without any perceptible change in speed or posture, but it seems unlikely that a larger bird could do that.
certainly until they find the last 4 people, i doubt they would let anyone -besides essential personnel- travel the area. and even then it would likely depend on how confident they are the standing bits of bridge wont come down on passing boats.
She is also a 9,971 TEU vessel. Most of the containers on her are international 40 foot 2-TEU boxes, so there's likely 4,986 containers. If you started lining them up head to tail, you could make a line of containers stretching from the impact point to a few blocks short of the US Capitol Building.

Landru, have you found a temporary position for your boat? I'm wondering if there was a lot of competition for the available slips from other stranded vessels.
I'm probably going to sell it which means changing marinas anyway. Here in the Mid-Atlantic most people either take their boats out of the water for the winter or move south. If they take it out of the water my guess they'll just delay splashing it until a channel is cleared.

This is a site dedicated to the handling of Key Bridge Response 2024. All information presented here is based on the available facts surrounding the incident. For the most up-to-date information and details on the different components of the response please refer to this site. This site is maintained by the Unified Command to provide information to the public on the status of the incident and response. We will continue to keep stakeholders informed through updates on this site. If you would like to receive email updates please subscribe to the incident mailing list.
Article: Today, USERT is part of the Evidence Response Team Unit (ERTU) within the FBI Laboratory. USERT divers are based out of the New York, Miami, Los Angeles, and Washington field offices and collaborate on cases across the country. With a total of 64 divers for the program, there are approximately 16 divers in each of the four field offices.
USERT members are not only expert divers—each one joined the FBI as an agent with a broad range of skillsets. Every agent can have a specialized collateral duty, in addition to their other responsibilities, which can take up to 25% of their time. USERT falls under this category, requiring tryouts to make the team and then rigorous training to prepare for the often grueling underwater work.
Absolutely. To jump to any particular conclusion just from seeing one patch would be an error. Anyway, thank you for pointing us (me) towards that YT channel, it does seem like it has a high fact density, which is what I crave. However, I still think shaped charges (the v-shaped ones we all researched when 9-11 was still a thing) will be the simplest way of breaking the submersed (becaue they work under water) wreckage into towable portions. But I might be wrong.
they guy in post #65 has some good stuff too. just watched him give an overview of how marine insurance works etc.

of Highway Bridges (1991)
ERRATA (August, 2006)
Since the AASHTO Guide Specification and Commentary for Vessel Collision Design of
Highway Bridges was adopted in 1991, there were no corrections or updates issued.
However, in making the Guide Specification available at this time, the following
corrections to the original document should be noted:
1. Page 4, Figure 1.5-2. In the flowchart at the “Is Bridge Adequate” box, the word
“Yes” to the right of the box should be changed to “No”, and the word “Yes”
should be added below the box on the line pointing the “Design Complete”.
what's a strat? (unfortunately with fender guitars and guitar strats and guitar bridges, im not having luck with google search)
"struts" I'm guessing... (?)
what is he a chief of? is he an official of this investigation?
Article: He said he's not sure any modern protections would have been enough to withstand a direct hit from a ship the size of the Dali.
"Could we build a Fort Knox, a nuclear bunker in front of a bridge? It's structurally possible, but it's not economically feasible. And so, even in the most extreme bridge protections that we see, at this point, I remain unconvinced that in a similar incident, that they would perform successfully," Schafer said.
That echoed a point raised by U.S. transportation secretary Pete Buttigieg on Tuesday.
"I do not know a bridge that has been constructed to withstand a direct impact from a vessel this size," he said.
