A bomb that's been sitting in the ground for 60-plus years could
be much more sensitive to vibration than it originally was.
Explosives can get very unstable in their old age. Not nice.

They used AMATOL then, which doesn't have a long shelf life and isn't in
any way water proof. 60+ years buried in mud and you don't have a hair
trigger device..... you have a rusty cylinder full of sludge :-)

When they find the next I'll gladly drive the truck to the dump.
