The crew did what they were told (paid) to do to get paid their salary and that's exactly what good pilots would do, simple, straight forward, end of..
Yeah, right!
They should do anything the company tells them to do, because they're paid by them.
They should heed any advice by maintenance, because they have the bigger picture from their office.
They should fly any fatiguing roster up to 100h a month without complaining, because the FRMS team says that their calculator shows only minor fatiguing sectors.
They should go into any discretion, up to any limit, because the company says its legal.
Simple, straight forward, end of story and we all can give back the fourth stripe.
If you really mean the above, you're dangerous aviators.
