The CAA have a very "hands off" safety culture, and it is that methodology that is largely responsible for the number of accidents.
Their view seems to be that if your manuals are up to date, you are assumed to be in "compliance". That being the case, they interfere no further. Most countries with developed aviation authorities know darn well that it takes a lot more than that to get fallible, imperfect humans to obey the rules.
In this particular case, you have to say that, no matter what the weather might be (within reason), if you stick to an approach/missed approach profile, you are completely safe. If you hit terrain, you aren't even close to the profile.
What this illustrates is that we can all make mistakes - and we all do, no matter how good a stick we might be.
I certainly hope that some mechanical or instrument problem turns out to be the cause, as I have a hard time believing that Steve Brown would wilfully break the rules.
And yes, his name was confirmed on the news a few minutes ago.
