What a profoundly depressing series of posts. As a crew we are all responsible for the safe operation. Although a lot of time in the cruise is spent sitting on our backsides, it doesn't mean we aren't doing anything. In fact the most perceptive thing I heard once from a CSD coming up to the Flight Deck was "Just what I like to see, bored pilots". Trust me, you do not want to see us working hard
If you really want to see what the job entails, why not ask to sit on the Flight Deck for T/O and landing, particularly during bad weather, or better still try a Sim detail, ask any training Captain. Almost all of us welcome crew on the Flight deck.
