In the B767 glory days, NS came back from Emirates and took over a dwindling fleet. Guys above him could not assist him with straight answers. He exclaimed over tea & biscuits (I was in trouble, again, for something trivial), "Tell me how many aircraft I have and I'll tell you how many pilots I need". Dead simple but it never, really, was THAT simple in GF. One factor in a very complex case but with the predictable and sad results of today's fallen falcon.
