SpaceX launched 24 Starlink satellites from Vandenberg SFB's SLC-4E at 9:11 AM PST on February 11. Booster B1100, on its third flight, landed on the drone ship "Of Course I Still Love You" in the Pacific, the 177th landing on that vessel. The booster's return trajectory produced a sonic boom first detected on the Central Coast near Santa Maria at 17:16 UTC, then propagating south to the Inland Empire near Menifee 8 minutes later at 17:24 UTC, covering over 200 miles as the shockwave traveled across Southern California.
