Landings have been fairly regular. I think the sand isn't a major concern as these aircraft are designed to cope with all conditions. A mate's son was a pilot of them and did many visits to the beach. The sand remains damp so limits air blast. I know the beach well, fished it innumerable times, learned to drive on it and the adjacent forest and airfield that was closed in a Willys Jeep and Landrover.
The area is great for military plane spotting. The Pembrey range attracts all types, there is a route they take through mid wales for low-ish flying.
A pair of Tornados did a fly-past before being taken out of service as a thank you for using the range and area.
Red Arrows used to do displays for Kidwelly carnival day as a thnk you too.
Pre Falklands Harriers did some spectacular training at Pembrey as the geography afforded Falklands-like conditions. LOW level down valleys over the estuaries to hit the bombing range from new directions to the normal circuit.
