Submariners worldwide mourned the tragic loss of MM3(SS) Michael Gentile during a field day accident aboard USS Nebraska (SSBN 739)(Blue) last September. Beebs over at beebsblog has obtained a heavily-redacted copy of the Command Investigation into the tragedy; you can read it -- along with the endorsements -- here, here, and here. (Click on each .jpg to make it readable.)
The bottom line from the investigation is found on page 9: "MM3 Gentile was a hard-working and respected member of the command. The EMT efforts were heroic and inspiring, prolonging the life of MM3 Gentile. The crew united to expeditiously surface and conduct a safe helicopter transfer while treating a wounded shipmate. The death of MM3 Gentile is recommended to be deemed 'In the line of duty and not due to his own misconduct.' "
Hopefully this tragedy will prevent this from happening to someone else. Submarining is a dangerous business, and the inviolable safety rules are written in blood. It's important that all Submariners remember that, and keep in mind Petty Officer Gentile and his tragic fate in everything we do.
