I've told this one before, but, as someone who is afraid of heights, i'll never tire of telling it.
On all 3 tours of Ulster, we were transported to and from Belfast in an Hercules. On one occasion, in mid flight, one of the RAF lads strapped something to his belt, pushed a button, and the tail-gate began to lower. At the required height, he sat down and lit up a ciggy, the smell of which drifted over to my ciggy-starved nostrils.
I said i could do with one of those and he immediately stood up, pressed another button, raising the tailgate somewhat. Then he put a belt around my waist, strapped it to the side of the plane, give me a ciggy then lowered the tail-gate once more.
I sat and joined him and, as we both watched the little people scurrying about below us, i remember thinking to myself, "This has got to be the best cigarette i've ever smoked." And i was right:-)
