So with the data revealed thus far, we have a fairly accurate reason of what/how this happened. But what human factor related issues actually "caused" this...or what was said earlier, "why"? The factors unveiled will probably very difficult to fix. The companies want us to fly as much as possible using the automation, because accidents seem to only happen when humans are flying the aircraft. The down side is obvious, automation is not always available or U/S, so then the human has to take over. But skills have atrophied, gotten rusty, and put aside. There has to be a positive medium. So many human factor issues to deal with in a blog.
Look at three deadly major accidents in the past few year, Turkish 1951, AirFrance 447 and now this (probably). All due to, too much reliance on automation.
