The loss of propulsion following the scram is what ultimately doomed the Thresher. Procedure at the time required a long process to restart the reactor, delaying restoration of propulsion. One of the first changes following the disaster was the implementation of a quick startup procedure, to get the screw turning again as rapidly as possible.

The water in the emergency blow lines resulted in the Sub-Safe system—strict controls on work on any ship’s system critical to the boats operation. IIRC, this was the genesis of the entire QA system in modern manufacturing.

Lotta ways things can go wrong down there, and when they go wrong... they can really go wrong.

... which means since I signed as QA for stuff that hasn't seen the light of day since commissioning they can still haul my butt in if a boat I was on sinks.
