Interesting little film. The bit with the magnesium flare reminded me of a photographic trip into High Gill Cave near Dent in the late 1950's to take a picture of the waterfall. I used some magnesium ribbons without realising the amount of smoke they created. I tried to beat the smoke to the entrance but failed and had to grope & cough. Had I waited 5 minutes it would all have gone out with the draught. You live & learn!
Thanks for that .........love the Bob Danvers-Walker style narration. Peter Herrison. Traffic on the "old" road too. Iirc I went down with my dad on Good Friday 1959. It was p*ssing down and we walked over from Edale station as he didn't drive.
Interesting to see the reel of what looks to be electrical cable outside the top entrance/exit, obviously just in the process of bringing new fangled electricity......
