I well remember explosive bolts - the 'no volts' and squib tests. Structures shops full of damaged Canberra navigator's hatches...
You had to be careful where you poked your Avo prods in those days...
Then there was the 'V' Bombers' light triggered, explosively actuated fuel tank 'explosion suppression' system. My God! Who dreamed up that bit of crap?
With only 14 tanks you'd think a chap would be able to deactive the right one, once in a while.
It sure puts another edge on 'Human Factors' engineering...
