This is a very appropriate revisit from 2012, I thought since we’re only a few days away from May 1. As in, May Day. Ha…ha…ha…😉

Anyway!

Mayday, according to “The Wireless Age” from June 1923, is an aviator distress call. It was agreed that just saying the letters SOS
wouldn’t do–that was the agreed upon message for telegraph, but it
didn’t translate so well to spoken words. The powers that be also
decided a simple “Help!” wouldn’t do. So they chose “May Day,” thinking
it particularly fitting because it sounds so similar to the French m’aidez (help me).
It has since translated to any radio communication of help, be it in airplanes or boats or whatever.
