Today, they found an old British aerial bomb from World War II in my city. Right in the middle of the city center. So 17.000 people had to be evacuated during it's defusal, and 40.000 had to stay in their home. Almost all public transport came to a halt for a few hours during the evacuations and the defusal. The defusal also had to be delayed because some idiots refused to leave their homes.
A few months ago something like this happened a few meters from where I live. Luckily I was on vacation at the time, so I didn't need to be evacuated. Still blows my mind to see these old bombs, that were thrown off a plane from a pilot that is probably long dead. Yet it still has such a strong effect for so many people 80 years later. And there are so many more that are yet to be discovered.
