distress signal

A distress signal is a standardized message or signal used to indicate an emergency situation where immediate help is needed. It aims to alert rescue services or nearby vessels and aircraft of a person or vessel in danger, such as being stranded, injured, or sinking. Common formats include Morse code signals like “SOS” or “Mayday,” radio calls, flares, or signal flags. The goal is to communicate clearly and quickly to facilitate prompt rescue efforts, potentially saving lives by ensuring responders recognize the urgency and location of the emergency.
