That's a good point even if it was said tongue in cheek. Any pilot that constantly complains about co workers, whatever the reason, is generally the cause of the problem. Most pilots from all backgrounds are fine ( once you get to an airline you do, in fact, meet a general level of competence). If an individual is having problems with who he is flying with it is because HE is the problem. It simply is not that hard to competently get the job done, unless you are a doosh. In that case, YOU are the problem. Not the people you are working with.
That has to be one of the most insightful posts I've read on FI. Very well put. I agree 100%. If you have more than 1 or 2 people on your no fly list it's time to take a hard look in the mirror.
