Been wondering were did "CC" or "Click Click" originate and what is the history of it.
From what I know the Double Mic Click or "Click Click" as some call it, was used in WWII by Pilots to send an Acknowledgement when they really didn't have time to talk.
It was also used by Field Radio Operators during Korea and Vietnam as well, especially when the radio operator couldn't really talk.
I have hears stories of Radio Operators using Morse code radio clicks to call for fire when they had enemy patrols all around them.
We here in combat flight sims use "CC" in text to send acknowledgements.
I can still find it mentioned on forums and discussion boards by and for IRL pilots.
Any one know any more on the history of "Click Click"?
Note: not to be confused with the Carbon Copy (cc) and Blind Carbon Copy (bcc) in emails.
