1983 not a chance but things have changed a tad since then
and I am very used to Penzance since 2002 not for work I may add
And in my, then (1990's), part-time job I even did a couple of, two years consecutive, stock-takes at B&Q Penzance, one memorable year occupying much of the afternoon/evening/night out in their Garden Centre because I was the one with wet weather gear.
No, I never saw the heliport in use
