“Danger UXB”— one of the greatest tv series ever! You watch the young men meet their rapid demise, see the cat and mouse between the German bomb and fuse designers and the UXB experts, and watch how jaded and old the UXB survivors get very quickly. Highly recommended!
The shocking thing is 1/6 of WW I shells were duds. I had no idea it was that high.
Not necessarily duds. The churned up mud was so soupy and deep that the impact force was sometimes not hard enough to cause a detonation.
