If a crew member falls overboard, what should be done immediately?

The immediate action of deploying rescue measures and alerting command is crucial when a crew member falls overboard. This response ensures that the situation is addressed without delay, maximizing the chances of a safe recovery. Alerting command facilitates a coordinated rescue effort, mobilizing additional resources and support if necessary. By initiating rescue measures promptly, the crew can implement established safety protocols, such as deploying a lifebuoy or a rescue swimmer, while also keeping communication open for situational updates.

Given the urgency of the situation, continuing the mission as planned could result in a tragedy, as it neglects the immediate need for rescue. Conducting a search pattern may come later in the rescue efforts but is not the first step; the priority is to enact rescue measures right away. Similarly, calling for air support may be valuable, but it typically comes after the initial rescue response is underway and should not take precedence over immediately assessing and responding to the overboard situation.
