When I heard of a 737 falling out of the sky in Russia immediately Turkish came to my mind...why? If FZ pilots are worked to death.. give it a try a THY 737 roster..and than you tell me if you would fly as passenger. Done that..never again.
I have seen and flown worse rosters, with more night work and multiple sectors. This is pretty much industry standard, in the low end of the market. And yes, sleeping on duty was fairly standard, esp at 03:00 or 05:00. Someone mentioned I was blaming all airlines. Not at all, but there is a significant section at the low end of the industry where this is quite normal.
But nothing changes. You can shout at the authorities all you like, but they don't even have the decency to reply. All they are interested in is an easy life and a nice pension, and squaring up to the likes of these shouty managers and owners is not on their priority list. Iy will take more than 60 deaths to get them out of the office.
