Harry Secombe's bus stop episode was in the mid 70s.
A Wessex was tasked to pick him up from Ballykelly and bring him to Aldergrove. One of 72s pilots, dressed in scruff order, went along as an extra passenger. On the way there they dropped him off on some deserted hillside complete with a bus stop sign and 9mm. pistol.
En route from Ballykelly the crewman inform H S that they were giving a lift to somebody. They landed, after a short search, and picked up this bloke waiting at a bus stop. He sat opposite HS and they were on their way.
Apparently HS was getting more and more worried because this hitchhiker was acting strangely and was fingering what looked like an automatic under his coat. However when all was explained he saw the joke.
The pilot involved was not at all happy standing on a hillside with just a 9mm. for company especially not knowing precisely when, or if, the Wessex would be back. He survived and later on in civil life flew the Pope around and the last I heard he was driving S92s in Brunei.
