bubbers44, et al; re “… they forgot the flaps. The warning system didn't work and they crashed. It will happen again if they don't fix it” (#2382).
‘They’ the crew, were operating in conditions where there are opportunities for error, and ‘they’ the crew, are error prone, as are all humans.
Your simplistic view implies blame; although you may not have intended this. This may be a result of oversimplification.
You also refer to those (they) who fix ‘it’; – which ‘it’, the TOCW (the operating conditions) or the human susceptibility to error. Who are these people, what are their responsibilities, and are these responsibilities of similar magnitude as those of the crew? Thus should they proportionally share the burden of this accident?
If the TOCW system had been fixed after previous accidents then this accident might have been avoided. Checks were introduced, but these did not circumvent error. Are they, the people at higher level who decided on checks vs a fix, to be blamed? No, but as with the crew and all of us there is a shared responsibility for safety.
How many Ppruners contributing to this thread knew about the poor working conditions (TOCW problems), how many of us have erroneously failed to select flap (on any aircraft) … how many have reported these issues, and if reported who took action and checked the result?
Not blame (after the event), but responsibility before the event; this isn’t simple.
