SpaceX Starlink Group 4-3 2021-12-02

Launched on a Falcon9 Block 5 rocket. This is the ninth launch and landing of this particular booster, and this is the 27th launch by SpaceX this year. (a record!)
Apparently they stopped numbering the Starlink launches by a simple count, and are instead labeling them by 'Group'.
These satellites are part of 'Starlink Shell 4' which will be in a 540km orbit.

Re-entry burn at 3:34.
