People use anonymity on here for valid reasons. However I'd be happy to identify myself if you PM me. I'm personally gutted that Sean died in those circumstances. I don't think anyone is saying "I told you so", in my case (especially as an ex Flight Safety Officer) I'm just concerned that such a well-known gotcha (there were posters everywhere, some archived on this site) somehow got forgotten over time. No-one is sneering and I'm sure that BA/BY didn't intend that.
As you know, accidents usually involve a chain of events, holes in the cheeses. The handle was one link in the chain, the bolt torque another.
All the best
