ON SUNDAY October 21 , 1979, the Bradford skyline changed dramatically. The 300ft-high chimney at Bradford Power Station in Valley Road came crashing to the floor within seconds, disappearing in great clouds of dust. Watched by crowds of people, the controlled demolition of the colossal chimney left the skyline looking strangely empty. The T&A - then a broadsheet - reported the event in Monday morning’s paper, telling readers that just before ten o’clock the chimney ‘stood out brightly in the sunlight - four seconds later it had gone and a pall of dust rose slowly from where it had been laid to rest.’
