As one of the engineers attending the aircraft on arrival, normally we would have had the aircraft hooked up and towed off within 10 mins, however another problem arose which prevented it being towed. At the momment the problem is under investigation so I don't want to say too much, however the delay was for safety reasons and in my view very much required. As with most engineers, we are fully aware of the implications of blocking runways etc, but safety is paramount and the disruption a consequence.
As for the strange door config, the 747 has 2 alternate gear systems, in this case the wing gear was fine as the #4 hyd system was OK so only the nose / body gear alternate system was used, due the lack of #1 hyd system there is nothing available to retract the doors.
