"I seem to remember that in the early 1980s nuclear drama 'Threads',which was written by Barry Hines and screened by the BBC,a bus was seen fleetingly being destroyed in the nuclear attack on Sheffield-it may have been an Alexander-bodied Dennis Dominator of South Yorkshire PTE." (thanks Alan Sinclair)
A scene in Sheffield prior to nuclear attack briefly features a Leyland Atlantean/Alexander and Dennis Dominator/Alexander of South Yorkshire PTE.
