We watched the Brit Series UXB about the crews that defused the unexploded bombs in London of 1940.
The bombs buried them selves deep in the ground and then had to be dug down to and defused. One kind had to have the explosive actually removed bu injecting steam and removing the explosive charge as a liquid.
After the explosive was removed, what was left was a harmless bombshell.
Bombshells are harmless
BTW..... The series is streamed off ACORN a source of very very good brit and Australian TV. Acorn is highly recommended
Danger UXB was certainly one of the very best series from that time period. Excruciating suspense while they were defusing those bombs.
