Glad to hear that your sons are ok.
It must have been quite a rough time for them and the crew. I can't begin to imagine their stress and thoughts. It sounds like only quick action and proper training kept that sub together. The entire crew deserve a lot of praise for getting her back to port. I hope their heroic actions are well-noted and recognized.
Prayers continue for your sons and the rest of the families of the SF, especially those of MM2(SS) Ashley.
