Why did Francis Scott Key bridge collapse so catastrophically? It didn't stand a chance. https://lnkd.in/eefBTUUQ Three issues IMHO: 1. Design considerations: no redundancy of supports should one major support fail, long, heavy and narrow, reminds this author of the Tacoma Narrows Bridge collapse in Washington State. 2. Operational considerations: no bridge traffic should be allowed when a container ship is approaching or passing under the bridge. 3. Maintenance concerns: apparently a crew was working on repairing lighting on the bridge and this may have caused the container ship to lose visual line-of-sight of bridge support in its path. #Keybridge #Tacomanarrowsbridge #safety

Check the short positions on Zurich Insurance, the reinsurer of Maersk Freightline.

Or it was intentional… I’m not a big conspiracy guy but there’s a pretty interesting sped up video at a different angle that has to raise your eyebrows.

perhaps upon impact of 150,000 tons of force travelling at 9 mph dropped it at the acceleration due to gravity of 32 ft/sec/sec

Because one of its main supports was hit with a massive container ship, should we over engineer everything to cover all eventualities? Nothing would get built…… You mentioned apparently maintenance was getting carried out and possibly it had an impact… too many assumptions in your comment

According to what i read, the ship lost power shortly before reaching the bridge.

I'm guessing too many people were in a hurry to get it built

I think the bigger question is how many other bridges are susceptible to single point failure and collapse from frighter impact? Or is this the only one in the entire country? In hindsight sight this looked like a disaster waiting to happen. What are the chances that one of these huge ships would lose power or otherwise go off course and hit a column? It has to be somewhat likely given the number that routinely passed under that bridge. I hope the redesign takes into account this real probability.

Personally I like some of the Conspiracy Theories floated, they're hilarious! Unfortunately, some make sense!!
