Tell you what, he was a tough 'un !! I saw his very first docu. carrying ladders up the outside of stack, fixing them, then scaffolding out on 'skyhooks' .... He could stand on two planks, steadier than most on the pavement. ... Then shift everything down a level .. again and again.
I see a guy from the states had dropped a line, because his firm demolishes chimneys in the same manner. ... Simple but effective, carve out the base, propping with timber, then burn the props away !! Excellent !!
