Wasn't that the same occasion that an 18 Sqn Wessex got totally iced up while doing underslung load training over at Junker's Farm, on the south side of the airfield? The sudden thick ice jacket it received made it too heavy to make it back to dispersal. The (scary looking) photo of it featured on the cover of the incident report.
I was posted there in 1980 and to my surprise, the first Met. officer I saw was none other than Bert Ford, off the telly.
