Wow, still, while the booster was lost that much success must have given them so much more data.

The details of how they stream all the data down in real-time reliably must be really interesting

Telemetry isn’t too hard to send down during launch, at least for the booster stage. It’s really only when you have hot plasma buildup in front of the vehicle that’s a problem for RF, which is mainly on reentry.
