I see they are blaming staff for the crash at Alton Towers (or human error)
This is what AT are saying - not what the HSE are saying

They are saying staff misunderstood a warning message and manually over-rided the safety's.
Straight away alarm bells ring with me... as I said before, there is no way anyone should be able to do this especially ride operatives.
Cheap undercutting of the control and safety systems. AT say everything was OK with the machine but the HSE haven't given an official report yet. I suspect they will differ.
