Food for thought?

Being questioned, the Chernobyl officials first refused to admit any flaws with the RBMK reactors - those had been around for years. They didn't know better.

Thus the blame was put on the officials and workers who were supposed to be well familiar with the rules. They were. But they weren't aware of the over ten accidents in other Soviet reactors that was kept secret by the government. So they knew the rules but not the risks because nobody told them of what had happened or what could happen. 

How can you run a new machine properly without first having read the manual, and if you run this machine for someone else who wants you to do a perfect job and who has the manual but won't give it to you, how do they expect you to perform correctly?

This all looks very simple, doesn't it? But it isn't. It just manifests the entire complexity of the Chernobyl affair. I wonder if we will ever find out the truth.
