"A ship in harbor is safe, but that is not what ships are built for."
-John Augustus Shedd

We have said it before and will continue to say, this is why we test. We have already learned a lot from this test and will continue to learn as we recover data and evaluate the hardware. No test article should be too precious to lose. A spare vehicle was planned from the start and is just a few months away from completion. The basic development approach is to quickly build, test and redesign the hardware to achieve many design cycles and maturity before building flight articles.
