Factual error: Glass gives the order to "submerge the ship." Submarines are always referred to as boats by their crew. (00:16:50)
Suggested correction: "Submerge the ship" is the correct verbiage. While submarines are referred to affectionately as boats by the crew, they are still ships and are referred to as such when the officer of the deck or commanding officer gives orders.
The Conn Officer will first order the boat to be Rigged for Dive. Upon getting a green board on the Ballast Control Panel (BCP) indicating all major hull openings are shut (red indicator means open), and reports from all stations that the boat is Rigged for Dive, he'll order the Diving Officer to dive the boat. The Diving Officer will then order the Chief of the Watch (the BCP operator) to submerge the ship and announce it; the Chief of the Watch, on the will announce "DIVE, DIVE' on the 1MC.
