1. Chernobyl
As many of us are now familiar with, Chernobyl is a ghost city known for the destruction of a nuclear reactor. Radiation poured all around the area. The tragic thing about the event is that the Soviet Union did not report and acknowledge anything about it until it was discovered by Sweden.
There you go the 11 biggest government cover-ups in history. We can only pray that these kinds of events don’t happen again in the future.
