Every time we board a flight, it is with the assumption that the blokes up front know exactly what they are doing.
I used to think the same thing. Do you make the same assumption about medical professionals and business leaders and ' experts' from other fields Kelvin? I have begun to realise over the last decade or so that the assumption is incorrect in every field but easier to expose in some. In medicine for example, with people often making decisions by themselves ( imagine if every doctor had a co-doctor equally qualified but slightly less experienced) , and with no voice recording of their procedures and public analysis of incidents, it is harder to confirm that there are good medical professionals and poor ones, but it is true never the less. The same is true for every field, aviation is no different.
