Mayday

"Mayday" is an internationally recognized distress signal used by radio operators to indicate a life-threatening emergency, such as a serious injury, a sinking vessel, or a fire on an aircraft. Originating from the French phrase "m'aidez" (meaning "help me"), it is repeated three times to signal urgency and prevent miscommunication. When a "Mayday" call is made, responders understand that immediate assistance is needed. It is reserved for situations where there is a real or imminent danger to life, ensuring swift and focused rescue efforts.
