Sorry to intrude, but in the early 1980s I flew (as SLF) out of LBA on numerous occasions, mainly to Glasgow on a twin turbo prop (?).
The locals would have me believe that in adverse wind conditions, traffic lights held road traffic at the end of the departing runway, as a precaution in case the departing aircraft was struggling for height.
I know it sounds far fetched these days, but was there any element of truth in that story ?
