Nobody can determine how tired someone else 'felt'. Especially when that person is deceased and cannot speak up for themselves. However, they may be determining that the crew should not have been fatigued, since it was their first day of a trip, and it was their responsibiliy to show up for duty rested, or to call out fatigued if they lack that personal responsibility. To sit up in the crew lounge and/or taking a red-eye to work when you will be on duty past 10 pm shows a lack of professionalism and personal responsibility. And don't cry to me about FO pay. She could have haad a crash pad for a couple hundred bucks a month and flown in the day prior at a decent hour and got a good nights rest. They most certainly were tired, but should not have been had they shown up for work properly rested, as their passengers expected them to be, and had every right to do so!
