Amazing aircraft the 777. If you ever get a chance to walk up close to one, take a look inside the wheel housing and notice how "clean" it is in there. No hydraulic lines or wires anywhere. That's because previous aircraft models would have hot tires explode after gear were retracted, with shrapnel often taking out essential functions. To reduce that chance Boeing Engineers re-routed all the lines & harnesses. Reminds me of the hot rods of today where they "sterilize" the engine bay.
