True Story From 1980: 1,000 Lbs Bomb Disguised as a Photocopier Blows Up Nevada Casino.
On August 26, 1980, several men in white jumpsuits wheeled what appeared to be a photocopier into Harvey’s Resort Hotel and Casino in Nevada. But the massive device was actually the most complex improvised explosive device the FBI had ever seen.
Inside the box was 450kg of dynamite, elaborately rigged so that it could not be disarmed. But a note attached to the bomb said that in exchange for $3 million, the bombmaker would give instructions as to how to safely move it.
But the FBI instead decided to try and disarm the bomb, setting it off in the process. The explosion caused serious damage to the now-evacuated building, but nobody was hurt.
