Study: Long commutes could fatigue airline pilots

AP tells us: Study: Long commutes could fatigue airline pilots :

One in five airline pilots lives at least 750 miles from work, according to a study by scientific advisers to the government, raising concerns that long commutes to airports could lead to fatigue in the cockpit.

I hope they are not driving to the airport every day, 10 hours each way at 75 MPH, it would only leave them 4 hours for work and none for sleep.
