It seems to me as though those who complain the most about the BMI issue could do with losing some weight.
While the company benefits by having pilots who are less overweight (they represent about 67% of sickness statistics) - one would think that those pilots who are overweight would benefit from the increase in quality (and longevity) of life afforded by losing said excess weight....
Anyway, enough rational thought - let's get back to the whinging!
