You don't know that. I remember watching a special on a similar occurrence involving Ed Link's (inventor of the Link flight simulator) submerged vessel being trapped below c. 1973. It was snagged on a cable while exploring a shipwreck (IIRC). Another craft either cut it or nudged it free. Two of the four men survived; tragically, one of the dead was Link's son.
I think we've had quite a few technological advances in 30+ years, so keep the faith. Let me see if I can dig up that story.
Prayers going out for these Russian sailors and their families.
Well, they can hope.
Now, IF they have the proper equipment (assuming it exists) and IF they can get it to the area right now, and IF they can deploy it right then and there, and IF it can actually do something to free the darn thing, then they have more chance than zero.
That is a fantastic story about cutting away cables.
Perhaps it could work with a net.
I haven't followed DSRV technology in quite a while, so perhaps there is hope, but 1 day of air changes everything.
As far as cables and such, frankly I don't see how it could be done, although there is a rumor that the CIA did that to recover PART of a Russian sub long ago.
Took a long time and tore the sub in half.
