Stainless steel is one helluva material. Already the first launch of Starship a year ago showed how tough the rocket was. It was out of control, spinning wildly in high winds, and yet it still held together and had to be blown up remotely. Anything made of aluminium or aluminium alloys would have been torn to tiny pieces by the sheer aerodynamic force alone. And now, the melting flap that was still capable of actuation and steering the ship towards a successful landing... One day, this sturdiness is going to save some lives.
