Okay.
I asked a question before with respect to fatigue, and the difference of fatigue when it comes to long flights and when it comes to landing and takeoffs. You explained to me, roughly, the timing of fatigue. Because we say that one size does not fit all, what type of fatigue exists for all three types of activities: long flights, takeoffs, and landings? Could all three of you give me short answers so the committee can have that information?
