Hi all. I worked for Ogdens, when they demolished Oak and Eldon,and did the drilling and burning,on the windows which can be seen in the photos. which enabled the way the buildings fell inwards...also did the drilling and laying of the charges but not laying the Cortex, the line or fuses,as it was too dangerouse,i believe...the actual explosive was useless on its own and useful for lighting the fire....When the buildings were blown I was stationed on the St lawrences junior school roof, to signal the area was clear...and was really surprised when the flats eventually were blown at the shock waves. near blowing me off my feet...the end of oak gardens refused to fall and Mick (the boss) had to go in and set the charges again as the cortex got severed by flying debris thus not allowing the charge to carry on,,,so it took two blasts to finish them off............I have some foties which have never been published so ill add them on here soon........Kind regards to all
