I guess it is something like that, but don't know for sure. I live in a major urban area so if they find an unexploded bomb it has probably been built over a couple of times since it was originally dropped. The most recent near me (about 800 meters away) was in 2021 and the most interesting thing about it for me was that it was a US bomb, not a German one.
