One is reminded of the Saudi 747 in KL taxiing to the gate with 1 and 4 shut down. The only problem being the Aux HYD pumps were OFF (Engineers taxiing, not pilots). Into a ditch it went, breaking the fuselage just behind the cockpit. Another one of those 'it seemed like a good idea at he time' events. It was a terrible sight seeing that lovely aeroplane sticking out of the ground like a giant arrow. Why look for trouble and make life complicated.
