Again though, the more complex you make the logic tree, the higher chance you have of an error manifesting. This is aside from the fact that there are no doubt many occasions where you don't want spoilers to deploy, so if they did deploy on one occasion after your suggested update was made, would there be a similar outcry to roll back that change?
The problem with responding to these accidents emotionally is that by nature we want to do everything to stop that particular set of holes in the cheese from lining up again. Where we need to be careful is to make sure that by closing those holes, we're not opening others elsewhere.
I think there needs to be some kind of HF research into how a broad cross-section of pilots respond to that situation and the call-outs made. If a significant number of pilots only retard one TL by mistake, then we have a serious interface problem. If not, then it could be argued that it was just a combination of tragic mistake and dumb rotten luck. Something that factors in all too many aviation accidents.
