If you're going to bump into something...

Last week it was reported that the attack sub USS San Fransisco was returning to harbor after a mishap while underway. One sailor was dead and more than twenty were injured, some seriously.

Interested Participant has links to updated information, and it looks like the initial reports were understated.

The USS San Francisco hit an uncharted undersea mountain "incredibly hard" and, contrary to a previously reported 23, about 60 crew members were injured. The submarine was traveling at high speed when it hit, sustaining significant bow damage which caused flooding in the sonar dome and ballast tanks.

New reports indicate the collision slowed the boat from a speed of 30 knots to about 4 knots almost instantly. I can't even imagine how the crew felt as they fought to save their boat.
