Do you not think he's a bit lite on aviation experience to understand fully what the environment is like?
It really is time this ludicrous notion is put to bed. Mahon did NOT need to have any aviation experience at all. I think this is where a lot of aviation "experts" come unstuck when it comes to this accident.
What Mahon really needed was experience in getting to the bottom of complex cases, and he had plenty of that.
I find it naive in the extreme to suggest he needed aviation experience. All he needed was knowledge of what was reasonable and he was able to acquire this from the many experts called to testify.
