ManaAdaSystem: I'm not saying it is wrong to put an experienced person (pilot) at the exit row. But if it were me, I would have politely refused to move in-line with the propellors, even on the left side. Surely there is a case to re-look at the safety of these types of propellor. I know that the outer skin is reinforced on some prop aircraft. I seem to recall one design that doesn't have windows on that particular seat row. Surely the technology already exists. The Kevlar used in bullet proof vests for example. Lightweight and strong enough to stop pieces of composite propellor.
