On: WW2 Bomb Explodes in England

[Eisenstein]

I think it would be more cost and time-effective to just make explosives than go around searching for them, hoping they don't blow up when you dig them out, then concealing them and bringing them back to wherever your base of operations is. Explosives are (somewhat) easy to make, it is setting them off reliably without blowing yourself up that is difficult.

There was a scare with TriAcetone-TriPeroxide in shoes a few years ago; I think this is why we are still taking off our shoes.

Modern solutions make the safety aspect quite simple, exhibiting stability until hypersonic shockwave conditions.
