What happens when someone falls off a US Navy aircraft carrier?

From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.
At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.
The Independent is trusted by Americans across the entire political spectrum. And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.
Your support makes all the difference.If someone sees the person fall overboard, they report "man overboard starboard/port side" to the navigation bridge. It is important to provide the side of the ship, as the ship will be turned in that direction. A life ring is immediately thrown over the same side, even if the person in the water is not visible. This marks the approximate point the person went over for navigation purposes.
The officer having the conn [control of the engines] orders an alert to be sounded throughout the ship, and a "Williamson turn" to the direction the person fell from. A Williamson turn is an immediate, hard turn that first puts the ship's heading about 60 degrees from its original course before turning hard back in the opposite direction until the ship's heading is 20 degrees off the opposite direction of its original heading. The rudder is then centred, and the ship returns to the point in the water where the person went over.
The hard turn moves the propellers away from the person. If they come into contact with them, survival is unlikely.
The "man overboard" alarm prompts some sailors to assemble in a pre-designated area to prepare to lower one or more boats to form a rescue party. Those sailors not directly involved in the rescue effort assemble at their "muster stations" to be counted. Muster counts are reported to the bridge, which should give some idea of who is missing from the ship's company and is presumably in the water.
The ship then begins a search and rescue effort to locate the person overboard and recover them.

I've been aboard several times when people have gone overboard. One time I saw a Marine being blown over the fantail by a jet blast. A fellow Marine jumped in after her and they both required rescuing (having broken a few bones on impact with the water). They had flotation gear, and the rescue helicopter that is always flying nearby during flight ops picked them up, aided by a rescue swimmer.
Another incident was a deck ejection from an S-3 at night. While the NFO (Naval Flight Officer) ended up hanging in his chute from some of the antennae (inspiring his new callsign, "Swinger"), the pilot ended up behind the ship. Even though the helicopter was less than a mile away, it took 20 minutes to find and recover him in the darkness.
We also had a mail clerk with troubles at home who decided that he didn't want to go back. He stepped off the deck during our last port call. While his shipmates watched, he slowly swam away from the ship until he slipped beneath the calm Mediterranean waters. We never recovered his body.
