Interesting to see this on HN as we dug out an entrance to a WW2 German bunker yesterday afternoon here in Jersey (the British island). Like urbex and WW2? Photos here: https://plus.google.com/photos/105983129534664287827/albums/6061218816958114817 https://plus.google.com/photos/105983129534664287827/albums/... Some videos also on our group's YouTube page, with a quick walk-through. We already have one of these restored and open to the public, and we were after parts and a bit of exploration. As for the accuracy, WW2 guns were good enough. This Youtube video on mechanical fire-control computers is very interesting and I've seen it come up on HN before several times. https://www.youtube.com/watch?v=s1i-dnAH9Y4 https://www.youtube.com/watch?v=s1i-dnAH9Y4 Lots of this equipment survives today. It was built to last and many people still collect it. We've also got about a dozen French and German cannon dumped from cliffs that we'll recover some day.

  Great stuff, thanks for posting this. What's being removed from the walls with the angle grinders? It looks like bits of rusty tube with little value... How was the air in there?

    Could be as simple as something to hang wooden seats or beds from. See for example the third photo in http://www.dailymail.co.uk/news/article-1041171/Violent-storm-uncovers-Nazi-bunkers-buried-sand-63-years.html http://www.dailymail.co.uk/news/article-1041171/Violent-stor... I wonder more about why one would, upon entering such a bunker, start axle grinding ones such structures.

      Little point in leaving stuff there I suppose. It will just rust away further over the next hundreds of years. Better to concentrate resources in a few of them.

        Sorry, I posted this and went to sleep so missed the replies. We have one complete and open to the public. We were allowed to dig out the bunker entrance to explore & recover anything interesting, then it had to be sealed back up. The last time this was done was in the 70's, as it is beach-side in an environmentally protected area.

  Is it normal to fire up an angle grinder and not wear eye protection where you live? In one of the pictures you can see spark bouncing off worker's face an inch below left eyeball.
  - jrockway 12y ago
    The sparks are hot, but don't contain much mass, so I don't think they're as dangerous as they look. That said, as an official paranoid person, I always wear goggles.

      Data/evidence to the contrary: The Royal Society for the Prevention of Accidents (RoSPA) Home and Leisure Accident Surveillance Systems (HASS/LASS) lists angle grinders at #3 in their top ten list of most dangerous tools, with an average of 5,400 injuries recorded. [1] "Angle grinders are one of the most dangerous tools in any workplace. They are used for cutting, grinding and polishing work. ... Most angle grinder injuries are from metal particles lodging in the operator’s eye. However, the most serious injuries are from kick-back, where the disc is thrust back violently towards the operator."

Interesting, but 1917-era is (late) WW1, not WW2. Quite a difference, not because of the size of the ships (the WW1 Dreadnought at 45,000 tons was larger than many battleships at Pearl Harbor; http://en.m.wikipedia.org/wiki/Dreadnought http://en.m.wikipedia.org/wiki/Dreadnought has a nice plot of battleship size over time), but because they had radar.
