> "I have to wonder why they haven't built a scaled version of Starship they could launch with a Falcon to test thermal protection designs with and run that concurrently with things they are doing in Texas. To iterate a design, you have to be able to examine the failures. I've gone through plenty where no amount of instrumentation would have been adequate, but Mk1 eyeballs did the job."
Because they've worked out that getting things up is relatively easy, it's the getting them back down intact that is difficult. Scaled models have issues because of the scaling, so if you can lob something up at full size, why not do that? It's also parallel development of booster, ship and production methods.
Yes, if you can get your eyes on something afterwards that helps a lot (and they're very much working on that), but they've also got some pretty impressive camera tech on board relaying live HD video which gives an awful lot of information alongside the plethora of sensors.
You also learn a lot more from failures than successes, so the iterative "test, boom, next" approach they're taking is valid.
