Hi MG, If it's the time I think it is, I reckon that's Apr 1979. As your Observer that day you gave me your camera and threw me out on to the Causeway with instruction "to take a photo of the Scout on the Causeway" Came out okay..which is a surprise as I've never been noted as much a photographer! Hope you are well. Good memories. JC
Your memory's not that good. In 1979, I was still a Sapper serving in Tidworth. Never did my pilot's course until 84.
Old age is a bugger with memory isn't it?

Plus, I've never been there, by air or by foot.
