There are a few comments popping up where posters are saying the pilots should be monitoring systems, picking up potential tech issues of their own accord etc, but I don't think that is the point of this thread.
The point is that a system that worked well was in place, it was a system that added an extra 'defence' in the Swiss cheese model. But in my opinion that particular defence has now been removed. The removal of just one defence creates an elevated level of risk. How many more defences will be removed before the remaining holes in the cheese line up?
