Clark Lindsey has some useful thoughts. As he notes, it would have been pretty amazing if this test had failed, considering what a trivial thing they were doing, and how much they spent on it. If it had failed, it would (or at least should) have been the end of NASA, or at least Marshall, as a credible developer of rockets (not that they should have such a reputation now, given the history of the past three decades). Another SpaceX could have been founded and another Falcon 9 developed for the cost of that test. Which tells you all you need to know about the cost effectiveness of the NASA jobs program.

Jeff Manber says that it was the wrong test, at the wrong time.
[Thursday morning update]
Chair Force Engineer has some thoughts on the Potemkin Rocket:
While Ares I-X was a low-fidelity test of a bad rocket design, the test’s fundamental flaws should not detract in any way from the Ares I-X program personnel who devoted the last three years of their life to making this test a success. While I strongly believe that Ares I-X should have waited until the 5-segment SRB was available, Ares I-X still taught NASA personnel much about ground handling operations and ocean recovery for the Ares rockets.
It would be churlish to imply that people who work on a bad project are bad people, and I’ve never intended to do that. I know from personal experience in the industry that sometimes you have to do what you have to do, and the real tragedy is that so much talent, and not just taxpayers’ money, has been wasted on this program. It was a huge opportunity cost, in time, dollars and people. The people who work on it both happily, and otherwise, deserve plaudits for doing as good a job as they could under the circumstances. Let’s just hope that their talents can soon be turned to more useful ends.
