When I was a lad....(yawn)...
I was interested in amateur radio (c.1960?). Somewhere on the shortwave band one could pick up a loud ghostly message at hourly? intervals which went on the lines of:
"All Moonshine Aircraft, all Moonshine Aircraft this is Croughton, this is Croughton. Do not answer, do not answer, Break - Alpha Delta Kilo Seven Niner Four Four.
I say again - All Moonshine Aircraft, all Moonshine Aircraft this is Croughton, this is Croughton. Do not answer, do not answer, Break - Alpha Delta Kilo Seven Niner Four Four. Croughton out."
Used to wonder who, or what Croughton was. Never did find out what it was all about - almost certainly something to do with SAC.
Something below on the subject from: http://www.merhabaturkey.com/1CAMMARATAAindex.html
There were two other missions we handled at airways. We made "fox" or one way voice broadcasts. SKY KING and MOONSHINE. SKY KING was a code name for the SAC B-52 airborne nuclear deterrent force. We never knew in advance when we would make a broadcast until the crypto man would alert us about an hour before the scheduled time and give us the coded phrase and exact transmit time. It went something like this: "SKY KING, SKY KING this is Incirlik this is Incirlik. Do not answer, do not answer break Romeo November Juliett break authentication is x-Ray Sierra." We repeated the message one more time followed by the phrase "Incirlik out." Other Airways stations also made random Sky King and Moonshine broadcasts. The Moonshine coded messages were similar except that we used the phrase "All Moonshine Aircraft". I never did find out what Moonshine missions were.
I too can't find out what Moonshine missions were - somebody out there must know
