UB-110 German submarine 1918
We’ve come a long way from thinking the world was flat and sailors feared they could sail right off the edge of the world. Take a look at this; it’s a UB-110 German submarine. This Control Room from a 1918 sub shows just how intricate our evolution has become. At least 24 control valves and 4 pressure valves that need to be worked and monitored can be seen in this one small section of the room. This shows the skill and knowledge it took to manually control a submarine.
