In order not to panic the thousands of passengers aboard a ship, especially when making emergency announcements on the loudspeakers, crew members have a secret code. If you hear the following, you'll now know what they mean:

• Code Adam: a child is missing
• Code Alpha: there’s a medical emergency
• Code Oscar: man overboard
• Code Bravo: fire on the ship
• Code Operation Rising Star: a passenger has died
• Code Red: an illness outbreak
• Code Charlie: a security threat
