Kursk ended up nearly nearly vertical with her bow buried in the mud when she sank! The angle was so great the AS-28 DSRV couldn't dock with her. The inwards crush could be from something on the seabed like a rock.
How come one side of the hole is round and the other side is square? Answer: because it was cut with a torch, this was caused by the salvage operation that raised her.
