I think large-scale engineering failures in other disciplines are always of interest here.

It's interesting only if there's a detailed report on the reasons. Otherwise this piece is news is just a "oh", instead of a "a-ha".

They'll start on the report after they finish mopping 1000 m^3 of water i guess.

This is more interesting than the "look what I cloned in Rust" posts at the least.

Considering there was a hotel lobby under the aquarium, it's actually a miracle that only 2 people were hurt. Too bad for the fish though. Also, there's a sentiment of "how could this happen, it was only upgraded two years ago?!" in all the articles I have read so far - maybe it happened precisely because of that ? But let's see what the investigation will reveal...

> it's actually a miracle that only 2 people were hurt It probably helped that it happened at 6AM ...

Yes, it could have been much worse if it had happened at, say, 6PM. Although some hotel lobbies can start to get busy even at that hour (airport hotels, etc).

I think we're richer for having this type of content, not least because someone has posted elsethread that the early signs point to material fatigue. The system works as far as I can see, and I think we're some way off the front page of HN being flooded by TikToks.

I don’t know about TikTok, I just know this post was submitted by someone with 50 karma originally pointing to a German radio station news site, in German. It was only changed to the Guardian later, perhaps by a mod.

Wow, how do you make pieces of glass that size?

It was manufactured in 2004 by a US company, "International Concept Management": https://icm-corp.com/ (side note: what a weird name for an aquarium manufacturing and design company)

uuuups... they better lawyer up...

And you do have first hand information, that this was the reason, as you speak with such authority of that matter?

Like, you do know that the temperature in that hotel was significantly lower than last year?

I mean, it seems possible, that it was the reason, (even though the water temperature itself hopefully did not change as the fishs do not like that) and the last nights were quite cold in germany, so stress from temperature difference is possible, but before I claim to know something, I wait until I know.

What exactly have we learned that’s valuable from this news?

That is one eventual first quick assumption by some (mostly nontechnical journalists), but nothing official and confirmed, or you have sources? Otherwise please don't sell this as fact. Knowing the place, it still had heating, so I personally find this also unreasonable.. would only make sense to me if it got to freezing temperatures or below 4°C, but that for sure wasn't the case.. I doubt that place was much colder than at other times, like maybe 2-4 degrees.. but if you have any real details on that this would be welcome.

If you're curious about the design considerations and construction techniques for large aquaria, the standard reference is Stachiw's Handbook of Acrylics for Submersibles, Hyperbaric Chambers, and Aquaria: https://www.bestpub.com/books/product/cid-151.html Plastics are weird, and examining the wreckage will give a lot of information about the failure mode.

A column of water that tall is nothing to mess around with. Even the smallest imperfection in the base materials can become a problem.
