A senior officer described a near-catastrophic incident involving a submarine that left its assigned patrol zone and entered a restricted area at high speed. The commanding officer intervened at the last moment, taking control and steering the vessel back to safety. The officer's affidavit, submitted to the Defense Ministry, emphasized the extreme danger posed by such mistakes, noting the risk of massive loss of life and financial damage due to submarines' limited detection capabilities. The court found that the stress from the event triggered the onset of diabetes in the officer.
