Trap one: "You aparently seem to equate slim with brains and fat with incompedence"
I am guessing by that liitle rant that you fall in the 'competent' side. I agree with most of the replies placed on this subject and I am by no means saying that all front seat crews are racing snakes, but surely we need to draw the line on such a highly visible trade. After all, they are Aircrew at the end of the day and if memory serves me correctly the medicals on entry where quite stringent so at what point do we allow people to literally let it go!
Fat does not equall experience. it equals eating too much and not excercising!
