There is really nothing here that has not come out in some form over the years. What I find interesting is the high expectation of vehicle failures expressed here. While failures are to be expected, the tone here suggests that costs and departmental rivalries are a large part of the reason.

Also, there doesn't seem to be the overall enthusiasm for the X-30 that I would have expected. This too is a decision that has to be made with costs in mind, but from reading here one has a feeling of tentativeness by those involved.

And throughout, I am left with the feeling that the people making this report expect some technological advance to make much of their work, and the money invested, a waste of time, to some degree.
