SI duplicated in simulators?
Lemurian brings up an interesting point on simulators, the flip side of which is that creating conditions to induce the proposed somatogravic illusion (SI) is likely not possible in a simulator.
Point being that even if the exact scenario was trained in a simulator the G forces would not be the same as felt by the accident pilots.
This of course would make the SI even more difficult to recognize and deal with.

Some things cannot be simulated:
The failure of the first Arian 5 launch was in part due to the fact that the only way to truly test an inertial guidance system (in all 3 acceleration axis) is to fly it.
