Mayday Calls – International Distress Signal

Mayday is an internationally recognized distress signal .

It derives from the French venez m’aider , meaning ‘come help me ‘. The Mayday call sign was originated in 1923 by Frederick Stanley Mockford (1897–1962)

The call is always given three times in a row ("Mayday Mayday Mayday ") to prevent mistaking it for some similar-sounding phrase under noisy conditions, and to distinguish an actual mayday call from a message about a mayday call.
