All this crap about who is going to sue who, I'll sue you if you sue me and if he sues me then I'll sue them, and I want damages from him for making this equipment work but I'll sue you for pi$$ing in my pond. Sorry, but all I can see emerging out of this tragedy is scavenging lawyers feeding from a free meal. There seems to be no end to the heartache of such a loss. The report is out, and is final, there is scope for discussion and for blame. But let the past rest, you can't change it, you can't control it nor can you control the future, live today, now.
Sorry rant over. Shoot me if you want.
