There are also more updates on the engineering disaster salvage operation of the MV Dali ship striking the Francis Scott Key Bridge causing the bridge collapse in Baltimore, Md. on the Patapsco River. The video also shows how salvors installed the detonators for using precision-cut demolition explosives to break apart the bridge truss and force it to slide off the MV Dali in pieces.
You'll also see the incredible cranes cutting off and removing large sections of existing bridge truss metal from the now re-closed channel. They closed this limited access channel on April 29, 2024, after the first ships to pass through the new limited access channel, a deepwater 300 ft wide, and a 35-foot deep access channel for larger ships, the first time since the MV Dali collided with the Francis Scott Key Bridge in Baltimore, MD on March 26, 2024. You'll see progress so far in this Baltimore bridge collapse.

I was watching it yesterday for hours before the postponement. He had great updates and commentary on the activity even with the rain rolling in. I was happy when he acknowledged you as well! Much respect between you both for sure! Captain Andy is a fixture around here! lol you both bring a level of experience and expertise to your information. Thank you.
I've been a subscriber of Captain Andy since the Golden Ray. You also have a good channel. Appreciate the information.
So many experts in comments, if they would go there to help it would be done in a couple of hours!!!!!
I live 5 miles away from the collapse site. I was watching Minorcan Mullet’s live stream and heard the big boom sound from my backyard. Sound carried downriver for sure
Fells Point is less than 5 miles away and we didn't hear anything.
Isn't it therefore so anomalous that the initial collapse can not be heard on any recorded footage, including the yamorous duo trespassing at Fort Armistead. You'd think that splash would have been legendary. In fact, the splashdown of the relatively tiny imploded chunk is far taller and made more noise than the recordings (and recountings) of the initial collapse. Anomalies galore. CONSPIRA is 64-part series exploring the numerous anomalies of this event, none of which are ever mentioned anywhere else yet found online.
@@chrisgrylewicz8182 Just wondering if you were upwind?
If that animation was the expected result, the Key bridge didn't watch the video. It had different plans.
there is no way the animation was the expected result. it doesnt follow anything close to proper physics. the top parts would not fall sideways.
That is because they found flammable materials in some of the broken open containers so they could not attach all the charges they intended.
I'm glad you brought up the perspective of the workers next to that 'small' piece of the bridge. It just drives home the scale of the operation in Baltimore.
Love how Jeff makes the kitchen cabinet install sound just as dramatic as the detonation of the bridge wreckage!! Keep it coming, Jeff. I look forward to all your engineering and remodel vids. 😄
Thanks! Will do! But it was much more dramatic for the kitchen install, for me personally! Lots of head scratching, and solving dimensional issues
@@jeffostroff Did you need to use explosives to take the old kitchen out?
I had the same thoughts.
Hey @jeffostroff maybe you should consider creating a second channel for your home engineering projects, or have a separate channel for engineering disasters.
No offense, I think a lot of us tune in and enjoying seeing the engineering disaster stuff, but get kind of tired of hearing you pitch your home engineering stuff.
@@JrTr_03 I saw the video and I suspect lots of expletives were involved and perhaps a fantasy or two of using explosives.😅

Locally, Captain Roy was in the chopper for WBAL-tv. That is who I was watching for the detonation.
Thanks for keeping up with the story.
saw their video, nice angle they had
@@jeffostroff да, с вертолётов(мне кажется, вчера листая прямой эфир Ютуба я видел три разных ракурса с высоты птичьего полёта) получились не только самые эффектные кадры подрыва остатком моста, но и и для восприятия картины в целом(как мне показалось - одна из рухнувших балок падая в воду могла и пропороть левый борт контейнеровоза). Хотя можно было ещё(The Show Must Go On) разместить пару видеокамер типа ГоПро как на капитанском мостике Дали, так и на самой подрывной ферме тоже. Спасибо за обзоры!
Between the Dali/Bridge clearing, the Packard plant demolition, and restoration, and the Gordie Howe bridge construction. It has been a great time for close up videos of what has occurred. These workers have done some amazing things, in very dangerous situations.
How is the splash of a much smaller chunk dropped from only half-height of original bridge, causing a taller splash, quicker dissipation, more waves, and louder sound? CONSPIRA site has 64-part series delving into the numerous anomalies. I never see anyone asking tough questions on other sites or channels.
@@ToxiCom-777 CONSPIRA? link? please, thanks
@@ToxiCom-777 Poor guy
Jeff your coverage of this has been fantastic! Thank you so much.👏👏
Super Mega impressed with the camera work. Crisp Clear. Well done!
The engineering and skills required to safely disassemble this array of concrete and steel is just as impressive as the same for designing and constructing it. Hats off to all involved in this massive undertaking.
The shrapnel is mostly those protective blankets that were used to catch the metal. The ones that traveled the furthest probably had pieces of metal in them. I’m sure those blankets are made out of Kevlar and all sorts of space age fabrics. They are quite heavy.
Well hello Dali, you're looking swell Dali.
Trusses are hard. If you blow each charge at the same time, you can't get momentum going in one direction to have stuff fall away from the ship. If you delay some of the charges to get momentum going in one direction, then the truss becomes unstable and therefore unpredictable in its motion. Those charges are usually connected via det cord not individually remote controlled for reliability and safety. That way they either all go off or none go off. The last thing you want is for one of the charges to not go off. Then you have to treat it like a hangfire in a firearm. Dangerous stuff. If you need a delay, there are special devices you can insert inline with the det cord that will delay the propagation by a very short period of time. The length of the det cord can also be used to create a delay.
Yeah, most likely used Det Cort to connect the charges. One of the things I miss from my US Army days.
depends who does the job. I bet the Army Corp did this and not a specialist firm. The top end companies have different means of controlling the sequence of explosions. It is not uncommon to have two separate circuits to each charge to insure proper timing especially in jobs like this where they might have a hangup. Something like a truss of this nature in particular they would be very careful to have backup to avoid a hangup that world be very very difficult to clear. This job was clearly not done by a top company and the result shows it. The government does everything low bid. sometimes you get the low bid result.
@@jamesb4789 The demolition was done by Controlled Demolition Inc of Phoenix MD
If trusses so hard and brittle then how did so so many melt and warp and wilt like hot taffy ?? Apparently many trusses were no stiffer than spaghetti. Only a blast furnace or added energy (from a beam weapon?) can cause girders to melt like that. Learned about this from CONSPIRA site 64-part exploration of anomalies.
Just being a mechanic with no demolition knowledge, what do you guys that know this stuff think of the results? My uneducated prediction of the results was that it was not going to look exactly like the animation
The upper members weren't the major concern. The bridge deck and the lower members had to be sheared off far enough away, so that as it fell, the weight of the entire remaining bridge section did not rake down along side the ship and pierce the hull. I think the results looked excellent since the main section settled nicely onto the bottom, and the individual section slid off and ended mostly vertical beside the ship.
I was watching 3 streams today - STL, Minorcan and the AP. And I saw Jeff on all of the chats. 😁
Here to see what angles I missed... and the algorithm.
The 'shrapnel' is all the rubber blankets designed to catch the liquid copper from the cutting charges. It takes all the force from them, so it flies pretty far. They are pretty clean cuts, so there's no steel flying around.
A kayaker going to the bridge was only a matter of time. This is America where being a fool is a given right. 😆
It was hunter binging again.
Kayakers are like vegans. They're always in the right. 😆
Ain't that the truth. There is always some SOB that just doesn't have any common sense.
If this guy managed to make a video and didn't risk anybody else's life, he is to be commended.
We were 2 miles South of Rock Hall and the blast was loud at 17 miles. No doubt what it was, not background noise...
The Space Shuttle B liftoff's were loud too, and eery as you can see the rocket go up, but you don't hear in for 35 seconds because NASA causeway was 6 miles from the launch pad.
We are off track here but a Falcon launch at night was eerily eerie as well. Bight enough to read the paper by and make the streetlights look like they were out, and in absolute silence. Then, as it cleared the tower, CRACK!! Back to the Key Bridge, by counting the seconds between the blast and the echo (and that was loud!) you can determine the distance, so it would be interesting to identify the exact place it echoed from and then plot the distance on a chart to see if the two match up.
Jeff - thanks for covering the happenings at the Key Bridge. You bring a little joy in the lives of us nerds!
Thank you for the explanation of did its go as expected? It was exactly what I wanted to know. Roanoke VA
I wonder how much one link of that chain weighs. Awesome shot of the tug!
Wow that is some complex rigging in that photo! Being a Rigger is super skilled trade for sure.
What you are missing is that a second vertical beam on the harbor side was only blown on one side towards the harbor. There was a comment over the marine radio recorded by Micorcan Mullet that this was intended. It acted as a fulcrum and turned the highest steel section bayward as it fell. The beam structurally failed by stripping a side off of the vertical beam all the way down to the bridge deck. It kept the higher section close to the bow when it fell over but importantly kept it going away. This was obvious on a helicopter zoom view that was circling the Dali after the blast. It's the only piece of steel still attached to the roadway on the Dali.
Alan,, PE, D.WRE, USCG/US Army Corps of Engineers (ret.)
Like cutting a notch or wedge in the back of a tree to direct the fall. But in this case they leave material in places
Sorry?
You're trying to tell us that, despite the animation which made their expectations very clear, it was actually their INTENT to have a damn great lump of steel sitting on top of the underwater debris - cos it is - and also have it leaning against the side of the Dali?
I do NOT buy that in the slightest . . .
@@nealc.6927 legitimately dont get too hung up on the simulation. it was a flawed animation to get the gist of what controlled demolition is and what is the general plan is. if you pay attention closely to the bottom section of the trust there are 2 detonations yet there are 3 cuts along the bottom that were not even where the detonations where. plus after the detonations the right side of the truss (part on the bridge) instantly gets horizonal momentum some how which is no where near realistic.
the main goal was to cut up the suspended part of the trust that was under unknown forces making dangerous to cut by hand all while not damaging the dali too much more. getting the truss sections away from the dali was a bonus.
@@nealc.6927 Look at the News 11 Helicopter feed. On the first pass from the east, the strip of attached metal is very clearly indicated. Which pushed the following bridge sections to the east when they fell and bounced off the Dali into the Patapsco Scenic River's tidewater..
@@cranberrysauce61 Exactly right, from the News camera coverage from the south-east, the top section very abruptly went east. Where did this momentum come from? Gravity would have pulled it straight down. The only possibility was an internal force not obvious at the time. It's only in the post-mortum analysis that there was an incomplete beam blast on the Dali. Someone looking at the results from the water stated over the Marine Radio that that was intended.
I think you are legitimately my favorite UA-camr
Well, I must be doing something right then! 😉
I'd have to agree @@jeffostroff
Mine too. I enjoy every video from Jeff, including his voice!!
That big truss was intentionally left on the Dali because there is flamable material in the damaged containers so they did not put any charges at the bottom.
I heard that they couldn't place charges down as far as they wanted on the pieces still standing because some of the containers had hazardous material in them. Didn't say what sort of material, but wasn't worth the risk. Also said that the bow of the ship had pumped as much ballast water as possible into to prevent any sudden movements. Still looks like a tremendous amount of weight on the bow between the roadway and bridge piers!
all in all, i say it was a successful demolition. the goal was to cut the truss to smaller bits for the cranes to easily carry out. on the original video on DVIDS it says " to create multiple, smaller sections, which allows salvors to use cranes and barges already on scene to remove these sections of the bridge and ultimately remove the M/V DALI from the channel" so the plan was always use precision cutting then use the barges to remove the pieces and then float the dali to move her.
plus if you analyze the animation you realize there are several inherently flaws with it, like the shape charge detonations do not line up with the parts the truss is cut up, and the unrealistic physics on the part of the truss that is resting on the dali. so it an animation of the gist of what was going to happen and not a simulation of the expected out come of the event.
That demo looks successful. Now they can clear the bow of the heaviest debris.
Once again another great video sir we really appreciate you and your work
Much appreciated
I think the blast went as planned not blowing the bottom and having it roll over the ship instead of falling into the deck
Another great video, the steelwork seemed to go away from the hull as planned. When you show the shots of the salvage workers next to some of the sections and lifting cables and chains it gives a clear perspective of just how enormous the steel sections are, and of course the immense weights involved in the salvage.
What was that kayaker thinking, did he think nobody would see him?
Love how the render somehow puts gravitational pull at a 45 degree angle.
I live about three miles from the bridge, and that blast *DID NOT* sound like firecrackers! It blew my curtains in and was so loud I thought it was loud thunder. 😂😂😂
Yes many other locals reporting the same thing
…and what happened to the little puffs of smoke? That was a huge toxic waste cloud.
Actually the truss debris left on the bridge was intentional. Captain Andy caught a radio transmission to that effect a few minutes after the BOOM. Think about it, they had all those smashed containers under the roadway and truss. They didn't want that mess rolling into the bay, so they purposely severed the top from the bottom, allowing the top to roll into the bay. The pieces left behind are still holding the smashed containers in place, but the pieces left are much more manageable now that the tremendous weight is gone.
That's a really great report you've put together for us tonight. I was chillin' with you in Captain Andy's Live Chat when this all went down. You've pulled a lot together in a short amount of time and it came out well, Thank you Jeff.
Wow that kayaker really showed the scale of the truss pieces still left in the water, thanks for another great video!!
It will be interesting to see if this thing is floating in 2 or 3 days like it has been stated on Andy's page. The ship is still nose down hard on the river bottom, and looked like it gained no buoyancy when the truss section came off.
Nice summary video!! Thanks for your time and effort.
Look to me it all went off OK Jeff, and most of the steel slip off, but I notice the
Dali front end didn't lift much out of the water still a lot of weight on the front,
now come the reflate of the Dali, Awesome video Jeff & I was very impressed
with the latest kitchen build and as a builder in Australia that was top notch 👍 👌
Great job Jeff, your videos and reporting on this has been fantastic. No B.S, and smoke and mirrors. That's the rubbish national and local news is slingly. Straight 🗑️.
It may not have been a perfect result, but it still seems like a very workable result. They split the truss from the ship and split it into smaller pieces.
Thanks JeffO. clear and informative. Great pictures
Jeff once again great video.
Thanks for the recap.
Thanks Jeff excellent report. Great angles and information.
Great summary ! That is what we view you for !!!
Loved following the channel during this salvage operation. Question for anyone. Very dangerous for the crews working on the iron. What PPE is required? I thought I saw harnesses but for working over water without netting should these have some sort of flotation protection? Dangerous job. Hats off to those doing that work.
Thank you, keep working.
I watched the video stream from several networks. There seemed to be a technical issue with the timing of the Loud Horn and the Countdown. Some of the reporters seemed to be taken by surprise. I was waiting for your video.
How much of that was shrapnel and how much was the 'blankets' they covered the charges with?
Good question it looked mostly like the black blanket to me
Wow! What a great job! Very scary as well! Thank you for this post!
Well done and documented, thanks for your effort, best wishes for generating a stipend
May has been rainy here, including a night with thunderstorms. I'm impressed how quickly this is going, especially considering the weather. I hear people complaining that they haven't reopened the bridge and all I can think is how fast this has all gone so far, and how long it'll be before there will be a new bridge. People are getting their complaints in early!
Those chains remind me of those in the famous photo of I. K. Brunel…
I’d bet good money this went exactly according to plan. The demolition was done by Controlled Demolition Inc of Phoenix MD. They’re pretty much the best in the business. They’re actually the same company that demolished the still-standing part of Champlain Towers South.
Pieces still there, one big chunk did kind of a cartwheel before going down and another vertical section stood there for a couple seconds after the explosion didint brign it down (lucky for them the cartwheeling part brought it down) Way too much credit is being given to that unidentified voice in the radio stating "it went according to plan" 10 seconds after the explosions
@@maumor2they had to adjust when in some of the spots there were exposed flammable material in broken containers and they obviously did not want to light the ship on fire.
12:55 The boom lift pictured, “Ultra Boom” I’ve used one of them before, 135’ reach, can be a little spooky til you get used to it.
The reason it did not detach is that they did not want to use explosives too close to the ship as some of the containers have flammable stuff in them.
That was a pretty accurate actual result of what should have happened. I don't think for a minute that the cement road way and steel beams under the cement would be drug off the ship. That will have to be removed the slow way. There may have been some structure left on the ship but it was minor compared to what was there before the detonation. There is still a tremendous amount of weight in that cement, the rebar and steel beams under the cement. There was a great view of the ship in one video that showed just how much lower the bow is than the rest of the ship. Great job on the videos Jeff and thank you for keep us up to speed on whats happening.
There’s a shot on one of the news feeds where the ‘bulbous bow’ insignia is visible. With it, you can notice a slight raise of the waterline.
Actually, that is due to wash/splash wave effect and once the water returns to normal, the ship is sitting the same. There should have been movement but the fact that there is now is not good.
@@jamesb4789 not knowing how deep it is right at the support structure the dali ran into is, there is a chance its also beached so it is actually resting on the riverbed and resting higher above the water than normal. so removing the metal section of truss might show any changes (plus there is still a large chunk of the concrete pillar on the ship)
Thanks Jeff, it has been fascinating. I wonder when Dali will finally be limped off?
2 more days at high tide
@@jeffostroff 👍
NTSB releases preliminary report on the March 26 contact of the containership Dali with the Francis Scott Key Bridge and subsequent bridge collapse in Baltimore.
Has there been any cause of the incident released as of yet? I saw court cases showing potential electrical faults that were known to the ships crew prior to departing.
great video!
Nice work. Chapeau - a tip of the hat.!
cool man. I have been curious about the chunks being recovered.
Does anyone have the exact time (to the second) when the button was pushed?
I'm trying to find sounds from a site about 2.1 miles away.
This site did capture the original collapse which sounded like rolling thunder.
EDIT:
OK looks like the timestamp on the video is close enough. Found it! At the site we recorded a boom at precisely 17:01:35. There was a sufficient pressure wave to rattle a large overhead door. This site is 2.1 miles from m/s DALI. The peak SPL was pretty close to the original collapse but obviously much shorter duration. Think of single round vs. entire mag dump. ;-)
Time is relative
5:01:26, on the StreamTime Live camera that was setup.
@@jeffostroff Be aware the streamtime live camera was 29 seconds off at the time of the initial crash. The time isn't right.
Cool video
@15:09...lol I see they are using tugs to move the ships now.
Was watching this from 3 different Vloggers? WOW, looking forward to seeing what they do to take off the rest of the trusses and move the Dali
Everything done was as design per Radio traffic heard on Capt Andy’s live stream.
*Here's why they (deliberately) did NOT place explosives in 1 spot. Hence the reason for the remaining piece.*
Start at :30 seconds in:
ua-cam.com/video/ry0KZpV2gTI/v-deo.html
*It's because there were flammable materials in a nearby damaged shipping container.*
That audio was cool
Damn those are good photos!
That piece of Cake is still connected to the road bed, I bet
11:57 YOU DID IT AGAIN!!!!! You called the Starboard side the Port Side! Remember Port/Left Four Letters. Although Port used to be known MANY, MANY YEARS AGO as the Larboard Side.
Also Starboard has 2 r's, so right.
Both my parents were in the Navy, I remember my Mum saying 'A little bit of Port, Left in the bottle'. Once you read that you will never forget it. Try it out.
During the replays, and especially the slowdown replays, I watched the ship itself very carefully. It may have moved a little but not enough to see. That's pretty much what I expected.
I think they have it ballasted down so it doesn't move until they want it to.
My Good friend is working there with 30 plus years of salvage experience told the engineers just because it works on the computer doesn't mean it will work in real time . Bingo !!
Been waiting on this one all day, the rest of the reports were key-rap :P
Jeff, look for the News 11 chopper feed from inside the harbor off the stern of the Dali. That is another different angle of the explosion.
How many pieces of the truss punctured the hull? Watching the arc of several of the pieces makes it look like they may be swinging instead of falling.
The saddest implosion that went wrong was the old Canberra Hospital in Australia. It killed a young girl via metal shrapnel who was part of the audience because it was a public event. This style of metal cutting is very high risk to perform. Never any guarantee how far wayward metal can fly once energized. What you identified as shrapnel is, well let's say something that isn't.
It hit her in the head. In California they were using shape charges to drop a power station and a piece of shrapnel cut a guy’s leg off.
I discovered Noticias Telemundo just before the blast and they had great video coverage. I was surprised how much drone coverage they had just before the blast and the drone coverage of workers on the deck right after the blast
I gave you some crap about, Monday Morning Quarter-Backing, on one of Your earlier videos. However, I've learned to Enjoy Your Prospective. 1,000 Pardon's My Brother!

Nice, they used cutting charges just like on 9/11. But, yes, I agree, the only sparks we saw when the boat hit the pier were the elecrical connections severing. At least some of these guys have made some fantastic money during this demo project. Can't stop a giant boat from hiitting a pier but I'm willing to bet engineers will try to think of something. If there were a long drawn out underwater concrete angle up to those piers, prior to the pier itself, it may stop the boats from reaching the main portion, just a though from an engineering family. I finally subbed to you...
Would placing delayed charges at the pivot points help?
Hey Jeff you talked about the Champlain tower, any idea when we can expect the next report from the authorities?
I was fishing about 3 miles from the bridge. Had a bass on the line when I heard the explosion. Landed that fish, then no bite from then til I left 2 hours later. We definitely could hear the explosion though, it was very loud and carried across the water
That must have been surreal
@jeffostroff It was. Everything about this has been kind of surreal though. Still think "oh, I'll just run across the bridge to Glen Burnie to the gaming store", but there isn't a bridge and now a 30 minute trip is over an hour. My husband's evening commute went from 45 minutes to 2 hours. It's just hard to get used to it not being there
Funny that the initial collapse was not even recorded by those two laughing kids at Fort Armistead. Other anomalies in the 64-part exploration on CONSPIRA site.
@@ToxiCom-777Do they sell CONSPIRA brand tinfoil hats there?
Buying a beer in Baltimore USA, I am sure there will be no one shouting drinks on the Dali? From Torrington NSW Australia 2371
Chessie is at the Bridge span they blew with the Gus the Claw this morning
How big is the damage to Dali?
Sees quite a lot of damage in the bow.
Fortunately, it JUST takes 46 days to dissemble the broken bridge, instead of 46 months.
Hi Jeff, the charges would most likely have been connected via shock tube rather than being individually commanded. Very simple but reliable way of doing things with an extremely safe medium. Shock tube carries explosive signals at a rate of somwhere around 3000m/s, so pretty damn quick!
In some of the views it appears that the falling pieces get hung up on the remaining piece in the river, preventing the stuff on the boat from moving as expected.
The sound of the hotel being demolished was muffled because the explosions were inside the hotel. The bridge was all outside, with only the outside of the beams covered with blast maps.
I'm guessing it is all 1 sequential fuse, with parallel lines to ensure all blasts happen. There are special fuses that can be inserted to create delays.
Free Advice: When showing before and after comparisons, it's best to use similar point of view.
Hi as regards the crew of the Dali,
I have a suggestion to watch. Karavir Singh UA-cam video: Inside the Accommodation of the biggest Maersk ship.
It's quite an eye opener as to what it's like to live aboard these container ships.
Right at 13:44 notice the huge warped, wilted, distorted girders hanging from North Pillar. What melted them?
When they dropped the old UC Medical Center building in Denver a few years ago, I heard it five miles away.
Jeff how are they cutting the steel sections underwater?
Good question. I do know the big 29 foot hydraulic grapple claw has been pulling up section of steel over 100 feet long
⚓️ Thanks Jeff ⚓️ nobody is getting arrested for paddling around a wreck… particularly in a kayak. Unless they get too close and make a commercial ship have to make an emergency maneuver to avoid. That guy had plenty of room. 🌈
I noticed that, relatively speaking, it didn't remove much weight from the bow of the Dali. I didn't see the bow come up at all after the blast.
Did the blast remove enough bridge steel from the bow to change the draft much, like enough for it to float a bit?
Apparently they filled the ballast tanks in the ships bow to stop it unexpectedly lifting and getting hooked on underwater debris.
If the R.O.V and diver surveys are O.K they'll pump out and the Dali will slowly rise.
Kaboom!
That was one loud boom
