A salutory tale. I've flown with that guy, or one of his many cousins. Bummer the CAA was so tough on you.
When I got my first job the CFI warned the one that gets you isn't the keen but inaccurate student but the high hour PPL who seems to know what they are doing but then at some point later doesn't. He hads proven himself right again and again.
On the other side of the coin the level of training imposed in this country does mean that of the hundreds of people I have flown with theres only two I recall that I would not get in a plane with and I managed to spot them before I got in. One got a darwin award shortly afterwards. Now compare that to how many people you would prefer not get in a car with and you could conclude someone is doing a pretty job somewhere.
