The most amazing part for me is that there seems to be no steering mechanism for this rocket. The fact that this was machined so well to withstand those speeds, maintain proper telemetry and not spin out of control/crash to earth, etc. is a testament to the builders. With that type of airflow, any slight imperfection in the fins would have made this a very short or nausea inducing video. Instead we get to view beautiful images of the planet we live in.
