I can’t add much more to what NASA’s own data from the Ares I-X launch shows, which was that acoustic vibrations resulting in thrust oscillations for Ares I-X, possibly strong enough to disable the launch abort system, at least according to the Air Force 45th Space Wing, did not happen. Or, as Marshall Smith, the Ares I-X Chief of System Engineering and Integration, said, “Bottom line is that …it was much lower than anticipated”
The Ares I-X data can be found on NASA’s Ares I-X website at this location. It’s a good read. And it further affirms that Ares I is a good and safe launcher.
