So back to the topic at hand. It seems the green hydraulic system failed, a logical conclusion given the catastrophic failure of the #2 engine and possible loss of fluid from that location. So, this would seem to indicate severe damage to that system from shrapnal or the complete destruction of one of the two engine driven hydralic pumps on #2. Correct? Also baffling to me is that there seems to be no isolation valves within the hydraulic system (other than the fire valve). Am I correct to assume that any leak in either of the primary systems leads to a loss of the system? Also interesting to me is that the nose gear steering is not triple redundant. If you lose the green system (which appears to be the case here), you only have the electro hydaulics to fall back on. Pardon the sophomoric questions but I find the though that goes into these designs fascinating.
