And a f-ing lot of good the investigation will be

Bob E summarises the likely conclusions of the investigation, full article at the BBC:

A lot of people collectively failed to do their jobs. Someone died as a result. That is unfortunate. No one person is to blame. This was not "corporate manslaughter". No one can be punished for this unfortunate and tragic accident, as it is no one person's fault. Measures are now in place to ensure it never happens again. Until it does. We will then dust off this report, change the dates and a few of the names, and go public with it and how horrified we are. Again.
