Dien Bien Phu Bristol Freighter?

My first thread of the year! Recently on Sky I saw a programme about post war sieges, Dien Bien Phu being the one that caught my attention. A piece of film shot across the runway showing C-47’s landing ended with the open mouth of a Bristol Freighter panting in the heat, but no chance of obtaining info. of the operator. I have photos of the RNZAF Freighters in the sixties in Viet Nam but can anybody out there provide information on the Dien Bien Phu one?
