Anyone else concerned by the text stating level flight and 250 knots, if that was indeed the case (and obviously crikey have higher res versions of the photo that allow them to do a closer examination of the controls), then the aircraft would be below stall speed at altitude above 10000 ft and I cannot imagine the crew being that casual or having a reason to be cruising below 10000!
I suspect if indeed the aircraft is showing an IAS of 250kts then in fact we are looking at a sim photo of an aircraft setup to do an approach, and looking at the charts that could well be one into Darwin. Why would their be a cabin crew member in a sim, maybe they were on a training course, it will be interesting to see the truth.
