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....
