I'm not an expert, but I can explain. It was hit by a massive cargo ship.
Build Back Better, the most literal campaign slogan ever.
@@grosario45I don't think you understand structural engineering.
That's pretty obvious, it's to find out why?? That not just a oops I backed into the mailbox pulling out the driveway scenario. That person steering had to know they were gonna crash 😢
@@grosario45 It hit a support structure and without that support structure it's going to fall like dominoes. If the bridge could be supported with only one support structure, then that's all they would have built. You'd never make an engineer. You'd fail the prerequisites to the beginning classes.
@@mistamajorThey lost control of a mechanically compromised ship and they sent out Maydays which helped stop regular traffic on the bridge! Sadly the work crew were sitting ducks, I wonder if any horn blasts were sounded from the ship….it might have helped given a few minutes extra warning? So sad for all the victims🥺
Prayers for those involved in this tragic incident.
Yes, people are in great need of prayer.
Bridge crumbled like it was made of toothpicks. Crazy!
Clearly see the ship lost all power minutes before and struggled to reverse.
Yes and usually going into reverse makes the ship veer to the right and as it did, into the pylon!
@@Mehranwahid Maybe it was the anchor they dropped, SHOCKER!
@@Mehranwahidwell said, ive been on board ships and it causes the ship to vear.
Tne power failed twice, Their should be back up generators on board.
The age and condition of the ship will tell us a lot.
@@CrazyForCooCooPuffsNo
Why would the electric system be tied to the main engines? I worked supply boats in the gulf, way smaller than this thing, and we had a dedicated power system.
It collapsed because a ship crushed it, wtf is that headline?
Indeed but one can agree the bridge is poorly constructed to withstand such a collission. Those pilons should have had decent concrete bunkers around it to prevent a ship hitting them.
It collapsed onto that ship. We have poor imfa structure aND NEED MOAR MONEY
And everyone though Build Back Better was a campaign slogan.
@@Kededianhard to deflect a 100,000 ton ship
@@Kededian It had "decent concrete bunkers". It's a big ship loaded with mega tonnage of containers.
A tugboat or two might have prevented the collision. They should be required for any ship that has to navigate under a bridge that close to the port.
Where are they😢😮😅
I suspect we will be seeing the Pilot soon enough.
The tugs took the ship out to the main channel and then left the ship at the appropriate point where the Bay Pilot took over. The ship had a mass power failure and lost ability to steer or control the engine. This video shows the ship hitting the bridge. ruclips.net/video/N39w6aQFKSQ/видео.htmlsi=84ViRdEjF9Jvs-WZ
The should have had russell crow and tugger out there
Tell me you know nothing, without telling me. 😂
I’ve been with SAR in the Rocky Mountains (Canada & the States) for decades. Cold water rescue victims can survive longer than might be thought. Don’t sound so eager to call it too soon.
I hope they are okay man
They have been in the water since ~1:30 AM (EST)
I witnessed a 12 year old girl just pop back to life, without any complications, after being found at the bottom of a pool. Warm water, no diving reflex here. More than FORTY MINUTES of futile efforts. By God, her pupils were blown. Brainstem death to me. I brought the grieving mom in to hold her for the last time and she was sitting up, calling for mom and fundamentally freaked out our entire crew. Esp when visiting a week later with NO lingering effects. Olathe Medical Center ER, Olathe, Kansas. Circa 1988.
That must have been other forces at work as never saw anything that dramatic in 20 years of acute care in ERs, Trauma Centers and as a street EMT. Prob shouldn't have thrown that in there but was sort of relevant except HARDLY the typical. Meant to mention my having to go onto a frozen pond to get 2 dogs that crashed through. I bet all on that 7 minutes. I crashed through beforehand per expected, down to bottom about 10 feet down so able to push up but holy hell, once head out of water, my brain was shutting down. Hard to think. Actually a second of confusion wondering what the hell I was doing.
Dogs got grabbed out okay (how is a mystery as I had to try to hold on a crumbling ice edge, reach over and physically lift them out of their holes. and I ain't that buff). My yammer POINT was that by ?4-5 minutes? if that?, I was struggling to THINK and a definite struggle to make my limbs work. Steep bank had me in thigh-high water quickly but I bet if it was 30 seconds more, I would not have been able to stumble out.
Sorry for yammer trigger. Keep up the good work. And key point about cold water survival. You Never Know. And holy hell, I think you'd appreciate The Last Breath. HIGHLY RECOMMENDED! I avoided it for a long time; seemed too much a bummer but absolutely fantastic and a must for any first responders (in my opinion). Cheers.
Thanks for your service
@@CoalCreekCroft Thanks for sharing, and for the recommendation. I have seen it-- definitely left me teary eyed.
There is a voice recorder on the bridge and as long as it was working you will hear what was said between the pilot and the helmsman!
It was hit by a freaking cargo ship! You needed "experts" to explain this?
any disaster brings out experts to explain the obvious...
You wouldn't think so , but then look at some of the comments here.
I'd rather have an expert that knows details than a random guy off the street. Sometimes there's finer details to be explained, even if this is a straightforward one.
The ship's lights went out before the collision, that loss of power was definitely a major factor
People have been blowing the whistle on bridges for a decade and they were and are ignored
This should not have happened. An adequate design that considered the risk of bridge strikes would have included risk mitigation measures like concrete piers with bumpers and non-trussed spans. Had the spans been something other than steel they might have withstood the strike enough for traiffic to clear the bridge and close it and had the spans not been trussed it is likely only two spans would have failed instead of the entire structure.
I don't think there is a bridge in the world, that could withstand a collision with a giant like that.
the bridge was fine. The ship was the cause
@@jeremywildrick-cole8373 All of that still wouldn't have stopped a few billion ton ship.
@@aynrand4288 trust me, the bridge was far from fine. These structures have been needing to be repaired, or replaced for years
The ship lost power, black smoke and lights going out twice.
power loss on a container ship is common. But it doesn't interfere with steering.
Now let's be honest, that bridge didn't look robust in any way. It looked rinky-dinky.
Dont need an expert for this
You'd be surprised lmao people are going to turn this into a conspiracy theory of some sort
@@matthewlupton1539already started to. It's sad.
They believe their viewing audience is incapable of understanding anything without an ‘EXPERT’ spraining it to them. The EXPERT doesn’t even have to be correct. But as long as they believe the expert is a true expert the viewers believe whatever the expert tells them. If an ‘EXPERT’ told them it collapsed because the piling was in need of repair, that’s what some people will believe until their dying day.
I learned this lesson a decade ago. I don’t watch cable news or read major media outlet news. They don’t tell you what you NEED to know. They tell you what they WANT you to believe.
The so-called expert called the Captain of the ship a "Pilot."😂😂
@@titomonroy3459 That's what they're called. The person / people piloting large crafts like this one, are called pilots.
ship was built by Hyundai.
no wonder they lost power in the middle of river.
my hyundai locked up engine in the middle of highway.

This guy drinks bud light
Samesysssss
God be with the victims family and friends through this entire ordeal. Prayers for all involved. 🙏🏼🙏🏼🙏🏼
The pier bumpers where insufficient for the types of ships passing under that bridge.
Totally agree!
Pier bumpers. Dammit, I was looking for that term on another comment. Spacing out too much. But yeah, I thought all big bridges had those bumpers ... but a joke compared to the inertia of a near-thousand foot giant cargo ship loaded a hundred feet above the gunwales. Google has so far been no help in trying to calculate that force.
"experts"
MFers I can watch a video. It's clear the ship was having some sort of mechanical issues w/ power.
Great coverage of a terrible, devastatingly sad situation.
I wonder how many years of schooling it took to determine that a massive cargo ship hitting a bridge support could cause a problem.
UH boat runs into bridge - and how much do you get paid ?
Captain is not driving inside a port, the Baltimore port pilot was driving, Who was the port pilot?
An indictment of America's failing infrastructure. This is much more than a cargo ship crashing into the bridge.
Absolutly. And people want to say " oh a cargo hit" helloo. Bridge was under constant survelliance and tehy are meant to withstand this sort of impact. Specially because they deal with daily traffic, mph winds and water. If a ships brings it down,, it wasnt safe to begin with
The harbor pilot needs to be questioned. They would have been in control of the ship.
Everyone knows that. 🙄
Ship obviously lost power and drifted into the bridge support, collapsing the bridge. Watch the video before yapping endlessly about something you know nothing about. First, all the lights go off, then when they come back on, you clearly see two things, first black smoke from the stack, and the sudden veering of the ship out of the channel indicating the port side anchor was dropped.
It's as if people have forgotten the ever-classic and ever-accurate "Sh@t Happens."
In the bridge camera footage, you can see the ship goes totally dark, the ship temporarily lost power right before it rammed it.
Twice
Engine and steering problem on board the ship, Black smoke engine problems.
The ships lights go off twice! This causes a complete power failure its frightening if your on board.
One of the anchors was dropped but it could not stop tbe collision
"Experts explain why the Francis Scott Key Bridge collapsed"
Gravity.
Why? The almost unbelievable amount of inertia in a MASSIVE, overloaded cargo ship.
They are cargo ships. They are going to be overloaded. that bridge was lacking maintance. Bridges are not supposed to collapse over a cargo ship. They have to be able to be built to be able to maintain all sorts of impacts.....specially because they have traffic, elements, waters to deal with everyday
This is why you don't text and boat.
Really? They needed an expert to explain?
"Well, you see, a boat hit the bridge."
The bridge’s pillar held up the way it was designed to. It was the 95,000 ton barge that slammed into the pillar that was the problem.
It didnt held up. It fell. Bridges are supposed to tolerate this sort of impact. specially since they deal with traffic, mph winds, water, trailers......this bridge was code red and the city is at fault
I was eating at riverwalk in new orleans when this same thing happened. A large boat lost power there was 2 minute warning. When it hit water flooded the shopping mall.. we ran for our lives..
Just curious trying to imagine this. Was it like a level waterfront where it pushed a ton of water over the edge? And what was the warning? Do they have sirens or something set up for such things? No worries, I wonder about a lot!
They needed to have protection barriers in front of the support structures. We have them in our area for our interstate bridges since we have barges going up and down the rivers. A barge took out I-40 bridge in Webbers Fall in 2002. Since this is major port why were there not any barriers in place.
They probably were in place (I have no idea but assume so). However, the inertia in such a massive moving object likely powdered 'em on impact. Not designed to sustain a direct hit of such a huge moving mass else they'd be a third the size of the bridge (I assume). Perhaps they WILL start making them bigger now.
I am not an expert, but I am a Navy Veteran who know how ships move. There was some sort of engineering casualty. Power out. Power on, black smoke, ship veers to its starboard. Power out, power on, ship hits bridge with 180k tons behind it.
Why? Accident? Cyber attack? Sabotage? Aliens? Whatever the reason, it is too early to know, if we ever really know.
The outcome. Some people died. The Port of Baltimore is closed until further notice. Commercial shipping and cruise ships are taking a big hit. Possible price increases due to loss of the Port.
This all sounds very familiar and very plausible.
It collapsed because the main pillars were totally unprotected against accidental impact by ships.
Excuse me? It got hit by a 100,000 ton cargo ship, and I'm no expert! 😂
When you lose power at the exactly time the ship is pointing toward the bridge structure, maybe we could look twice for sabotage. And maybe the Coast Guard could watch for other bridges in similar positions vis a vis harbors and bridges. 0:34
It wasn't sabotage don't create conspiracies.
I think it was similar circumstances when a ship hit another bridge in the South somewhere, sometime in the past (yeah, great ref I know). Just too much went wrong at the worst time. Then again with your point of the timing, that's EXACTLY what tingled my Spidey Sense.
@@killer008r - thank you for your well-researched conclusion.
@@TheSuzberry I mean, seeing as I work on that bridge, and was driving to work when I heard about it this morning. I'd say my conclusion is a lot better researched than yours.
every time a ship pulls into an American harbor there is an American pilot on board they sleep about 10 miles off the coast and get to the ship and drive it in
Who will pay to build back the bridge ?
Yeah, accounting and insurance gonna be hell.
What about macro economic impact?
Baltimore is a big port
I doubt bridges on federal interstates have any insurance
We will.
The USA government 😢😮😅

From the video clip, the ship-Dali was on the correct voyage route of passing the bridge before it lost power. If the ship pilot just do nothing, the ship should be able to pass the bridge safely through gravity force. Unfortunately, the pilot tries to stop the ship by dropping the ankle and reversing gear, which caused the ship deviation from the correct route.
Furthermore, lot of world trade shipping schedules will change - Port of Baltimore is out of commission for the foreseeable future.
Seeing that bridge abruptly end like that…🫣…literally been a recurring nightmare since I was a kid. I’m driving up a bridge incline and the road suddenly disappears and I’m teetering on the edge😬 It is triggering to see it in real life.
Cue the Sunshine Skyway bridge flashbacks.
One reason why huge container ships like Dali are so economical to operate is that they are powered by a single, massive engine. Lose that engine and the ship loses the ability to navigate. New bridges are expensive. Perhaps it is time to mandate that similar ships must be escorted by two tugs when passing under vulnerable infrastructure.
Based on the raw information, the vessel lost power twice. However, the main reason was the wrong decision made by the pilot and master. When the first engine broke down, the vessel still had time to avoid the situation by using steering. However, in the video, the pilot decided to go astern, which caused the vessel to lose control. As a result, it collided with the bridge.
And just how many engines do you think a cargo ship has?
@@robertpalmer3166 only 1 main engine. But in this case, the reason is from generator blackout lead to stop main engine. You can see the lights are turn off in other video.
The question is why did the Ship hit the bridge? Why is nobody asking that
Been on that bridge before plenty of times now my fear of bridges at 27 is fully active
I’ve ALWAYS been scared of bridges above and below. Have serious anxiety when there’s no other way to go.. I pray there were no casualties but I just heard about this..
The bridge was old. A modern bridge would have at moat collapsed around the pillar and not such a long stretch. Modern bridges can withstand the failure of one column/pillar
😮scary and sad.🙏🙏🙏
Incredibly bad luck. It has to be a very right hit to do this... yet it hit it😅
What would we do without experts ? Very tragic accident, my heart felt sympathy to all involved.
There should be some camera footage on the bridge that investigators can review. Standard SOPs nowdays
Extremely shocking to see the collision of the container ship with the bridge. Our prayers are with families and friends those who are still missing from this tragic accident. Its too late to ask this question but from my sailing experience onboard ships we use tug boats when we are passing high risk areas for safety of all. We do that in Suez channel entry exit and in Panama as well. If they had tug boats in this channel to safeguard the bridge and the vessel passing under bridge when passing such very high risk areas they would have had hope to pull the ship to the channel back during its sudden black out which is my opinion if you all can do this for other channels such as exmp. Missisipi river any river commercial ships passing we could minimise such catastrophic accidents for future. If you think vessels must be guided by tug boats when passing such a bridge in any river etc for safety all mankind thank you.
I am an EXPERT at watching the video of that cargo ship hitting a bridge support pylon causing three sections to fall off into the water. It is obvious what happened. Looked like the ship was having problems of some kind. But looking at the smoke stack, it was under power the whole time.
How many more bridges are old and rusty and weak if a ship crashes to it.
The more government involved ,the longer it will take to get ANYTHING done
Yes
Centuries? I don't think so. The bridge is only 50 years old.
Not talking about the bridge. Using the formal local Pilot system has been used for hundreds and hundreds of years. Probably informal for long has ports have existed.
And already a rust bucket judging by Google maps images.
It looks like they meant to put why it collapsed totally and not near the support, and the simple answer is the design of the bridge, it relies on the supports to “balance” over the channel, you take out one of those supports and you lose that balance, and then gravity takes over
SUMMARY: a Boat knocked the bridge down.
It’s video not pictures.
LL
I WANT TO KNOW THE LOST OF LIFE . WE CAN SEE WHAT HAPPENED TO THE BRIDGE . WHAT THE RECOVERY EFFORT. I'M PRAYING FOR THE FAMILEY'S
looks like we need stronger bridges
So you’re going to have experts tell us what we just saw happen a ship from Singapore crashed into our bridge it came tumbling down suspicious to me .
Who are this people? How many calls for help they had responded to?
Anyone that has watched Scandal knows this play. Mechanical errors affect stock prices. It has to be human error right? Smh
“Black smoke indicates more power from the engine which increases the steer-ability of the ship” Wrong! Not if the transmission is in reverse, then it’s all prop-walk. Hire some experts that understand boats!
Can we have the stuff on the boat?
What is wrong with the captain
So much information, so little answers . Who owns ship, why increase in speed why not n middle of structure instead of close to main support structure
This & similar incidents raise serious questions about US infrastructure that is way out of date because a modern design would've had more than adequate pier protection!
The boat hit it that’s why don’t need nobody to explain that
These are Experts? They told us nothing.

Going forward adequate tugboats must escort vessel during critical important passageway
Was that ship heading out…..or coming in ?
Heading out.
Outbound.
@@CoalCreekCroft thank you
Later reports made that obvious , but I couldn’t really tell from the first report .
Take a look at the "dolphins" Florida put in place to protect the new bridge after the Sunshine Skyway Bridge disaster in 1980 - that was another incident where a ship lost control and collided with the bridge support structure.
That bridge fell like it was made of match sticks in the video...very concerning... unfortunately, sometimes crap just hits the absolute fan and the pilot may have done everything right and those technology issues of the lights going out are suspicious. Someone is in trouble no doubt, we'll see with the investigation.
We won’t get answers we never do and I believe it was done deliberately.
🤦♂️ A MASSIVE cargo ship ran into one of the main supports for that bridge, so it’s no surprise the bridge went down the way it did. That’s a lot of kinetic energy that NO bridge would be able to withstand especially a ship that size going the speed it was. Imagine a train 🚂 crashing into your house and your house collapsing like a house of cards afterwards only for you to say, “iT’s cOncERniG tHe wAy mY hOuSe cOLLapSed 🥴”. It’s literally simple physics. The bridge did exactly what it was supposed to do on a physical scale, but unfortunately it was not able to withstand that kind of force from a ship that size. NO bridge can!
@@andrewbell7996 yes, I understand that a big ship hit the bridge with big force...science and physics. Thanks for the explanation. I already know I'm not smart, I've known my whole life. I'm an iDiOt 🫥 I get it.
I bet we'll find out that was one of the most critical places to hit it for a complete collapse. Yet still surprised me the whole thing went down.
So......at anytime your going across a bridge you have to worry about a ship taking it down.....awesome.
Thank you for explaining, I was confused as to why the bridge collapsed before watching this video. How stupid of me.
why was the ship so close to the bridge before it lost power? why was the ship headed straight for a main support structure? Where was the back up generator? Where were the small ships that guide the larger ones around. Why was no warning given? Even over radio?
Why don’t you bring some structural engineers on? - as they are the actual experts in terms of infrastructure.
It's pretty obvious why the bridge fell. It was hit by a massive cargo boat. Duh!!
Were they heading out to sea or coming into port
Heading out.
Outbound.
What caused the bridge to fall, it’s called gravity!
It broke and now it's a shovel ready project!
Oh I had assumed it was a giant
F me your manufacturing standards are in the bin, Boeing now whoever built the bridge, here in the UK the concrete plinths are big enough to keep ships away from the bridge structurr
Focus in saving lives! These was a massive power failure, the anchor dragged and the bearings in the pylon were not sufficient. Why don't you interview Sam at "What's going on with Shipping"? Talking heads do not enlighten of save lives. Infrastructure/safety chack fail!
A ship ran in to it?
Here they come, experts …
Let me guess, it was built in the 70s when builders cut corners to save money?
A bridge is supposed to withstand a hit to its pillar no matter how big or heavy the object is. 🥴
No, no it isn't. There isn't a bridge in the world that would have been able to withstand that large of a cargo container, smashing into it.
People said, there was a power outage and smoke coming from the ship prior to the collision with the bridge. A lot of lawsuits out of this.
I think a five year old can explain the bridges collapse.
Ukrainian captain works for SBU Budabov
It was hit by a massive ship that’s why it collapsed 🧐
Amm no. Its a bridge of fuks sake. They are meant to tolerate this sort of impact. the bridge was not well maintain. I expect lawsuits and I hope they paid out like they should.
Is there oil spill ?
Experts!?
Real heavy Boat lost power.
Puny Bridge has no pillars.
Heavy boat, hit bridge.
Gravity made Bridge go falling down, falling down, falling down
Be very interesting to know the background of the crew, especially the captain and pilot. Anyone believe they were hired on qualities other than experience, competence, and skill?
