While mistakes in aggregate are inevitable, individual mistakes are not, and neither are certain categories of mistakes.

Not paying attention to your airspeed is the sort of mistake you should be able to eradicate.

I want to know why a pilot who says that he is "very concerned" with doing a simple visual approach is allowed to have a couple hundred lives in his hands in an airliner. This is Piloting 101.

Mistakes are inevitable, but we shouldn't just throw up our hands either, especially when this particular mistake comes down to straight-out incompetence and a pilot who's afraid of a basic and straightforward flight operation.
