I think it is pointless to discuss the technicalities of all of this in too much detail. We need a broader perspective and yes, a social context. How can you see this terrible event in isolation of the race to the bottom of the last few years? The article below describes it aptly as a "sick pilot being a symptom of a sick industry".
Germanwings crash in the Alps: sick pilot a symptom of a sick industry
Of course, in a
PR attempt to be seen to be “doing something”, most airlines, worried about their profit margins and perceptions of the flying public, are now introducing a policy of always having two crew members on the flight deck (already common in the USA). This cheap and immediate measure seems a sensible policy at first sight, but clearly the law of unintended consequences applies here as well. What if the cabin crew member is the rogue member of staff, locks the door, restrains the remaining seated pilot and takes control of the aircraft to nose-dive it into the ground? Somebody with minimal screening on a zero hour contract? (the reality in low-cost airlines, where there is a high turn-over of cabin crew because of the poor working conditions).
Currently, when a pilot is suffering from one of a multitude of situations which is impairing them mentally, from fatigue (very common) to a specific mental condition, there is no adequate support system in place. The perception is that we will be out the door and back on the dole with no hope of returning to work. This is not conducive to the best possible mental state for those sitting at the controls to do their job correctly.
The truth is, a cancer has been eating away for quite some time at the aviation industry as a whole. Low cost airlines have initiated a race to the bottom and through sheer market forces legacy carriers have been forced to follow suit. In order to understand how it came to this we have to go back a few decades.
It is unclear how much Lubitz was aware or involved in all of this. What is clear is that he lived in this social context and became socially alienated to a pathological level. Was it a feeling of lack of control over his own life and future? A hopelessness about nobody caring for him that he could no longer bear? We will probably never know.
We believe it is more useful to provide a general framework of the current state of the aviation industry than what is being spouted in the mass media about this tragedy. It has never been much in the public eye, but pressure has been building up for quite a while now. Morale is at rock bottom in most airlines. Unions are either non-existent or powerless to stem the tide, never mind offer an alternative that can inspire their members (we would suggest taking a good look at London tube drivers). What was once one of the best careers to aspire to is now quickly becoming a laughing stock. Why would anyone bother going through all this drama when the public perception is of a pilot just pushing a few buttons “as these things fly themselves anyway” (nothing could be further from the truth) in some cases to earn less than a train driver?
The point is not to empathise with Lubitz or justify his actions, despicable as they are, but to try and understand why a human being might act this way, so that people can then try to ensure it does not happen so easily again. Within aviation in the last few decades, this has been the goal of aircraft accident investigations: not to apportion blame to any particular individual, but to try to uncover a chain of events in order to draw the lessons. Rather than just throwing our arms in the air and declaring Lubitz was a “madman” or a “rotten apple” living in a social vacuum, our aim should be a lot higher. As such, we cannot see this event in isolation but have to see it within the context of the degeneration of the aviation industry in particular and the prevailing malaise in society in general.
