They keep this up and they're going to need ~~a bigger~~ more boats. Also, that video from the barge was solid the whole way through. Did they just improve their antenna stabilization or are they using Starlink to relay video and data from the barge?

The need for more ASDS has been discussed repeatedly (search for A Shortfall of Gravitas).

The video is actually usually pretty good. The LOS on the landing is due to the intense vibration causing temporary signal lock failure.

Probable sighting of Upper stage and payload over limerick Ireland, Just south of Alkaid in Ursa Major at ~06:34

Probably

But can't they record it to an SDCard or something and show it to us after it returns to port? It would be nice to see some more clear videos of landings...

Yes, they record the landings locally, but they don't always share the photos and videos afterwards (especially these days since it's pretty routine).

You can see all the landing videos from previous missions here: https://www.elonx.net/spacex-first-stage-landing-attempts/

Forgive me if I missed it but I don't recall them ever giving us S1 telemetry all the way to the drone ship. ISTR we've had some in the past, but I don't think I've seen it all the way down. Seeing it tick by is so much more visceral than the excellent plots that are produced.

Staged at about 7900 km/h and 67 km
Topped out at 7100 km/h and 115km.
Velocity drifted up to 8066 km/h at entry burn.
Entry burn dropped that to 5750 km/h.
Only picked up 6 km/h before the reorientation took hold.
And bled enormous velocity all the way to the landing burn.

That was fascinating the watch.
