hmm. just when you think you've heard it all. wasn't sure where to put this. from WW2 1945
On 14 April 1945, only 8-10 miles off the British coast line, U-1206 was safely cruising at 200 feet when the commander, Schlitt, decided to use the toilet without the help of a trained specialist (the system was complicated). Something went wrong and when the specialist arrived he misunderstood something and opened the wrong valve with the end results that large amount of seawater got into the boat. The seawater reached the batteries directly under the toilet causing chlorine gas to form and the boat had to be surfaced immediately right under the enemy. When the boat reached the surface they managed to blow clean air into the boat but at the same time an aircraft bombed the boat causing extensive damages leaving the boat unable to dive. Seeing the hopeless situation Schlitt had no choice but to destroy his secret material and abandon ship to safe his crew.
what a shitty way to go
