The US Navy has released groups of documents to a court order. One thing they show is the haphazard state of the sub program that contributed to the sinking. They fixed that with the SubSafe program.
The second revelation is that the USS Seawolf says that they were in contact with the Thresher through various signals for 24 hours after the accident. The scene was chaotic but the Seawolf called for silence as they traded signals such as banging, keyed mikes, sonar pings and garbled voice messages. If the sub had achieved near neutral buoyancy it may have taken some time to sink to crush depth. It's the line by line Seawolf account that is most compelling.
I can see the Navy holding the details that surely ended up in the Subsafe program close to their vest but it may be that quick end to the Thresher's crew may have been window dressing.
