The man had at his command all of the resources of an aircraft carrier. He has machine shops, skilled personnel, subordinates tested and proven for their leadership, initiative, resourcefulness and knowledge in their own professions. This includes having a medical staff qualified for independent duty. They can take apart, repair and rebuild aircraft, ships, nuclear reactors and the most complex electronics around. Governors and Presidents and Fleet commanders don't have the immediate access to resources this man had. If they need quarantine quarters, they can go out on the hanger deck and with the personnel on board, build such in short order.
Near as I can tell they didn't do much of anything except sound abandon ship. The CO couldn't even organize a field day with Clorox to deep clean his ship.
I don’t know much about the Navy, but I would assume that the subject of handling infectious disease on a ship is something that would be standard training for officers. Is this accurate?
I think there was a recent series on FOX that featured something like this.
