Having to analyze 80 year old bombing records during new constructions adds to the long list of downsides of wars
BTW, Europe has similar problems with dud artillery shells, old minefields, etc. And it's not just WWII, nor just Germany. The most infamous is probably https://en.wikipedia.org/wiki/Red_Zone_(World_War_I)
The money quote is:
Conventionally the air forces designated as "the target area" a
circle having a radius of 1000 feet around the aiming point of
attack . While accuracy improved during the war, Survey studies
show that, in the over-all, only about 20% of the bombs aimed at
precision targets fell within this target area.
Imagine a place like Afghanistan. I assume neither USSR nor USA records are accessible for the people there. Their landmine issue is just too sad
