Imagine a toilet so complicated, it requires special training to use. That’s German engineering for you. This submarine deep water toilet featured a series of chambers and airlocks to blast waste into the sea, akin to a poop torpedo.
On April 14, 1945, just 24 days before the end of World War II, Captain Karl-Adolf Schlitt, feeling the call of nature and over estimating his toilet training, dropped a deuce and then everything backfired -— literally.
Sewage and seawater were unleashed throughout the submarine. This filthy deluge short-circuited internal batteries, filling the sub with toxic chlorine gas. Panicked, Schlitt ordered the sub to the surface, only to get bombarded by Allied planes. Ultimately, they had to abandon ship, and while most of the crew survived, the U-1206 now rests on the North Sea floor.
