A little ghost story from the greet Tin-ter-web
The A44 road from Aberystwyth to Llangurig passes Pumlumon mountain, and on more than one occasion motorists have reported seeing a WW2 bomber flying silently above them, about 15 – 20 feet off the ground near Eisteddfa Gurig farm. One such person, Paul Jay saw the bomber and was expecting to see a crash in his rear view mirror, but there was no crash and no sound at all. A week later Mr Jay was watching Foyle’s War on ITV and saw the exact same footage that had been played out above the A44 as he drove past the week before. Looking into this further he was amazed to find that Foyle’s War had used actual archive footage in the programme, and that the scenes on the television had been real. In fact, on the walk from Eisteddfa Gurig farm up the mountain you pass an old mine working. Lying next to these mine workings is the wreckage of an old WW2 bomber, the very same bomber plane seen in the Foyle’s War footage.
