A boom was detected near Cypress in Orange County on the afternoon of February 11, more than 6 hours after the confirmed Starlink 17-34 sonic boom that morning. The timing rules out the SpaceX launch. Camp Pendleton, which regularly conducts live-fire training and exercises that produce loud booms audible across Orange County, is the most likely source.
