Seeing that a mate of mine is about to do a 737 crash course in a clapped out old Ansett sim,
Nothing wrong with the Ansett B737-300 simulator. In fact the fidelity is first class. When you do a heavy landing it feels just like the real aeroplane - that is a bone jarring hit and you know all about it. Having said that another operator using the Classic has it's heavy landing impact technically "smoothed out" (saves on maintenance costs) so you hardly know you are on the runway. Good for the ego but not realistic in any way.
