Wartime accident, Cwm village, nr Dyserth, nr Rhyl North Wales

[Icare9]

I think we need a bit more help. Have you checked your local newspaper archives? Any date? WW2 or later? Mention of paratroops would indicate 1944 or thereabouts, possibly C46 or C47.
Is Cwm near a WW2 airfield? Is it in high ground or is the hill the only high spot in the area?
Why would an aircraft be in that area?
Give us more to work on and we'll do our best.
Check with your source for more details, please for anything more.
