I’m surprised at how fast this video was made and is and it’s fully animated

[afonsoel]

Me: "Only four and a half minutes long video? Why so short?"
CN: "On the 26th of March, 2024..."
Me: "Wait, what?"

A slideshow of basic sketches would have been good in that timeframe; getting out an animated 4 minute video explanation is legendary.

RIP to the 6 road maintenance workers, and anyone else, who lost their lives when the bridge collapsed.

For those that don't know, THIS WAS A WELL MAINTAINED BRIDGE!. It wasn't some old rust monster, and wasn't on the " watch list " for poorly maintained bridges.

[Pissedoffdetective]

What is known so far is. Mayday was called before the 1st power loss.

Emergency all anchor drop was performed between 1st and 2nd power loss.

The cops managed to close the bridge before impact... hence low casualty numbers.

As an "Air Disasters" aficionado, I've learned that at least 2 problems need to occur for a disaster & you show them here, loss of power at the moment they're passing an intersecting channel which diverts the ship into the support.
Thanks!

Was definitely expecting a about this from you, just not this soon. Amazing jab once again 👍🏻

[dmhiix]

I'm pleased to see a video from an actual SME. So many people with no understanding of piloting have been rushing out their responses.

[mattgies]

Times like these, I'm glad I have such an eclectic collection of channel subscriptions.

Maryland here.... that Bridge has been considered a landmark for decades and people would often take pictures with it in the background.

It's happened before. In 1980, the Sunshine Skyway Bridge southbound span collapsed after being struck by a wayward cargo ship. The replacement bridge supports are protected from future collisions by concrete _dolphins_ on either side of the shipping channel.

a plum of black smoke usual means that the EDG is tripped on, unfortunately with restore power, full astern and rudder shifting to make emergency stop was not enough due to lack distance to the tower from the vessel which was going 8 knots. dropping the anchor would not help again because the short distance to travel and the speed of the vessel. the observation of + and - pressure known as bank and suction effect is a very good point as to why the vessel swung to starboard, something I didn't think of initially nor has anyone else pointed out in the YouTube video or in the press as subject matter expert. Bravo Zulu "Casual Navigation"

[Markyroson]

Media is now reporting that the vessel did lose power. I hope when the report drops that you revisit this.

[mikefochtman]

Good that you stick to what we DO know at this point. There are already those that are making wild speculations. Some evidence that the ship lost electrical power for a short time (video shows lights going off and then coming back on) but that's about it. Looking forward to you making another video when we know more.

[REzado]

I have been subscribed to you for a long time and I was waiting for this video. I wasn't expecting it to be so soon. That's insane workmanship. I'm from Baltimore and have been on that bridge millions of times. You explained in that video of the area like you were a local. Good job mate.

[Danieloncarevic]

That was fast. We're looking forward to a follow-up once more information is released and the causes can be properly examined.

Great job! 👍

[bc-guy]

Hats off to Casual Navigation!! Still just hours from this tragic incident and yet an episode with explanatory graphics and navigation points already plotted is prepared and explained. Very Impressive. Sort of mutes all of those spouting the ridiculous conspiracy theories.
This channel is a treat. Thank you!

[person]

Whoa, that is some fast production! Bravo!
