> But what's new in Starship?

The planned recovery mechanism (the aerodynamic fall, with a very late righting maneuver and landing) is still quite new. They've successfully tested it once (which is great!), but the Starship concept really hinges on that being an extremely high reliability maneuver.

I would argue that, until SpaceX can demonstrate that landing maneuver is high reliability, that the Starship concept isn't proven.

I say this as a massive fan of Starship, and someone who is extremely excited by the promises of Starship of they come to fruition.
