This is "A Brit, curious about everything around him, lives in Germany and has a video camera", so appears to be just repeating whatever he's picked up from the likes of YouTube and news media. Just wondering why this one is picked vs the probably hundred or so others that weren't (many of which would have at least some engineering background to flaunt). |

I just read an article in an online (reputable) newspaper about the accident but no real information about the cause. The article mentioned that the cylinder should have been heated to 80 deg. C to treat the material. Appearantly that has not been done during the recent maintenance cycle. But the article doesn't state whether not doing the heat treatment is part of the cause. Maybe it was deemed unnecessary and somebody who thinks otherwise has a huge 'I told them so' moment. |

The architect (in ~2003) reckoned that you could shoot a bullet hole in the aquarium, and nothing but some water would leak out. Catastrophic failure was "impossible". |

I used to have or came across (if I remember right), some C or D cells (possibly Ray-O-Vac), which said something like 'Absolutely 100% Guaranteed Totally Leak-proof', with huge amounts of horrible brown (glue like) goo, coming out of them, like crazy. Great pity I didn't photograph it! Engineering is full of learning by dramatic failure. Hindenburg Airship disaster, oops we shouldn't have used Hydrogen, it can burn/explode (the fuller details, with flammable outer coverings and war-regime NOT being allowed to purchase US Helium, Static electricity being able to set it on fire, via mooring ropes etc, are probably the real factors, especially). |
