I can only assume you were flying a jet and I doubt a high powered jet flying above Mach 1 would not act quite the same way as a low powered biplane flying along at about 100 mph.

I suspect the low powered biplane would be far more susceptible to any turbulence than your modern jet, and that is all AnKor is attempting to simulate.

Plus a modern jet has a far more sophisticate seatbelt system holding you rigidly in place versus a simple lapbelt in the WW1 planes which allows you to move your upper body around due to banking or turbulance.
