The best part of this flight was seeing the full reentry with no visible hot spots or burn through like we've seen on every previous reentry of Starship. Seems like they have the heat shields really nailed.

Yes, reuse of the heat shield has been the biggest question mark of the whole program and this is by far the best result of any launch so far. This is the first time it looks plausible that you could consider reusing the heat shield.
