Good info you guys placed here.
I have been flying all sorts of 777 for the past ten years and to be honest, never gave too much thought on fuel leaks.
What Boeing tries to do is to give us some sort of guidance for possible failures and as they state in their manuals, they cannot write a checklist for everything. The crew judgment, after consulting engineering and other sources, is still the best option for unexpected and not-checklist-covered events. The crew must avail of the technical information provided by the experts on ground; however, it is up to the commander to decide the best course of action. IMHO, the guy who landed against company recommendation, did the right thing. The folks on the ground are not under pressure, they have the books in front of them, the coffee is ready, and everything seems to be all right.
