Back to the original idea, I can't remember how many tests NASA has done on fatigue and the effects on the human body. Although; they never seem to get the FAA to impose new flight rules and duty rest... Now JBlue does one test with a few pilots and a doctor with their own definition of what fatigue is, and things my change to a 9 hour day? Give me a brake. I wonder what the actual tests showed? Maybe the pilots showed fatigue with less then 8 hours and they are trying all sorts of formulas to show otherwise....If you put enough money (Lobbying) behind anything, it will get past....LOOK OUT, 9hr, 10hr, 11hr.... P.S. Yaaaa my 50th post....
