What happened this time, who knows. But if you all bother to Google sub accidents you'd find that their has been many from all nations that have them, and even within just the last couple decades. Everything from running aground and hitting undersea mountains at full speed, hitting other subs, other ships, to surfacing and taking out fishing trawlers. A record that would equal the recent surface ships of the 7th fleet. High tech or not, not all are mechanical failure and mishaps. Sometimes things happen so fast that their is no stopping an incident once a sequence of events is put into motion. Not sub related, but these things always reminds me of the Navy's Honda Point incident of 8 Sep, 1923. involving 9 destroyers where 6 were lost and 23 sailors lost their lives.
