Twin Pin was - I believe - the right answer. It had slipped my memory that I had posted about it before - well it was in 2007!
I read the story in the F540 of 78 Sqn when I was a baby Wessex pilot in Sharjah (and the F540 scribe). There was a report of a "trial" of SS11 at the time of the Radfan campaign IIRC, which would put it about '64-'65.
A brace of messieurs from Nord Aviation had arrived in Aden to carry out the trial. While en route for a range sortie, they were diverted to a "contact" up-country; some nasty men in a cave could not be zapped by the Hunters because of the tortuous approach path.
So the 78 Sqn Twin-Pin, complete with French civilians
did the deed! The 540 certainly reported it as the first "guided weapon in anger". (Not QUITE the way we'd do business nowadays!!)
78 disbanded last year when its Merlins became 846 NAS, so I guess its F540s will be at AHB, and I imagine that '64/'65 will be declassified by now.
If not - I'm in trouble!
