Well said.
You've summed up what many of us instinctively know after years/decades of flying. The problem is, the people making he decisions in the senate inquiry haven't had that experience, they will have to be clever enough to work out that the gradual change that has ocurred with little obvious consequence so far, has led us to be boardering right on the edge of an accident, and the conclusions that they come to will decide if that accident ocurrs.
If they are indeed that clever and can see that, we may move in the right direction again. If they aren't, or if there are such powerful economic forces at play that they don't, we will see the result on the six o clock news within the next ten years. My 2 cents.
