The damage seen on the Ares I-X booster occurred as a result of parachute failure, which caused the rocket to impact the water harder than expected. Ares I-X manager Bob Ess briefed reporters today on the preliminary data from Wednesday's test flight of NASA new rocket, and said the parachute failure was not a significant [...]

Different center of gravity making it less unstable.

Oh. I thought they also simulated the weight distribution in the dummy stage. I thought they'd go for bettery fidelity with the proposed "real" upper stage.
