Reading some of the comments on this thread, and others, I can't say I'm tempted to throw the old 'Flightsim pilots' comment, as there are a load here who would probably be downchecked by Microsoft.
This really is a joke. In my current lot, we always laughingly say that when the 'Bus comes back from a quick MOT and oil change, if any setting is where it was before, it obviously relates to something that hasn't been checked. That's the way it's been for all my airborne life, but so what?
It's not up to the ground crew to set the flight deck up. It never has been, nor (pray God) will it ever be. Anyone who assumes every setting is going to be the way they left it is someone who has no business being there in the first place, or who has very minimal experience of real life. Switches and settings the way they were before? Before what? Quite a few would be in the wrong position for departure, as they would have been set for an approach and landing. Whose 'fault' is that then?
If an angineer has sat in the seat, do you not think to adjust it again to suit you? Or do you hit something solid, then blame the engineer because you weren't able to reach the controls?
Sympathies, as before, to everyone who suffered from this dreadful (and avoidable) tragedy. However, like it or not, the blame (as has been properly proven) lies front left and front right.
