ROUTINE vs rare, you are talking about one in a million event.
We are talking about the military, or experimental aircraft, or aviation theory here. We are talking about passenger carrying commercial aviation. A one in a million event would be quite frequent these days & I don't believe that the industry could sustain a weekly fatal hull loss. The traveling public would just not accept it.
Tweeting aircraft to get maximum performance at the detriment of a fall back position where the pilot can get it home when the automatics fail, combined with less & less pilot training due to cost, is pushing the boundaries of what the customer will find acceptable. The never ending quest for lower fares & more profit has a dark side. Try telling the customer that they are in a lottery & bad luck - your number just came up. Worse still, try telling that to the family members left behind.
Things cost. Safety & reliability cost. And the sooner people wake up to the cost of flying around the world at speed in comfort, with safety in mind, the better! Constant downward pressure on costs, combined with constant demand for more profit isn't sustainable. And that applies to all aspects of business.
