There is a book by Haruki Murakami called Underground that is a bunch of interviews with people who survived the sarin gas attack in Tokyo. It's OK but the thing I found interesting was a lot of people didn't realise what had happened and continued on to work rather than hospitals. I can understand three was a lot of confusion and chaos when it happened. It reads though as if Japanese people where like not going to let a sarin gas attack stop them from getting to work. It kind of made me angry and frustrated I don't think I finished that book. Destroying the world to save it a good read if your interested in the topic though.

Aum bought a farm in Western Australia in 90s they flew in with a lab setup and where testing sarin on sheep. That farm also had a fair bit of uranium on it too. There was a seismic event that hasn't really been able to be explained that happened in the same area at the around the same time. It's sort of a local conspiracy that it was Aum testing nuclear weapons. One of their plans to bring about a global apocalypse was to obtain nukes to trigger seismic events that would destroy the world.
