Impressive stuff...
Although i didnt actually handle explosives, i used to detonate charges for geological surveying in the Vale of Belvoir. All small undergound stuff...unless you pulled the det cord with the charge still atatched up to the surface, then detonate it. Used to make some nice craters
I can still almost remember the sequence...all mounted on a box, foot on plunger, wind handle to create electric charge, while foot is still on plunger, hook toe under another plunger and lift it to detonate charge. Chrikey, i must have done hundreds of them...all 30 years plus ago
