Oh, those daredevils! They’re always willing to pull off another incredible stunt to gain fame and glory. Sometimes it’s something incredibly stupid, but sometimes it is simply incredible.

“The Chernobyl disaster was a catastrophic nuclear accident that occurred on 26 April 1986 at the Chernobyl Nuclear Power Plant in Ukrainian SSR, which was under the direct jurisdiction of the central authorities in Moscow. An explosion and fire released large quantities of radioactive contamination into the atmosphere, which spread over much of Western USSR and Europe.
