I did my one and only stint in the Falklands in 1983. less than a year after the war had ended. The concrete runway had been covered with an interlocking covering - AM2 matting I think it was called.
One of the 'sights' to see at Stanley was the edge of the bomb crater that could be clearly seen at the side of the runway sticking out from the AM2. We were told that the bomb hadn't denied the Argentinians the use of the runway as they had managed to operate down the side of it.
