This week, federal authorities announced the arrest of Yinpiao Zhou for allegedly flying a drone above the base on Nov. 30. Zhou, 39, who most recently had been living in Brentwood in Contra Costa County, has been charged with failure to register an aircraft not providing transportation, and violation of national defense airspace. Federal documents outlining the allegations say Zhou’s drone flew over and photographed sensitive areas of the base for 59 minutes, the same day a sensitive payload traveled to space aboard a Falcon 9 rocket. Security forces personnel contacted Zhou and another person, determining the defendant had the drone in hidden inside his jacket. During an interview with investigators, Zhou admitted he flew the drone from Ocean Beach County Park. Sign Up for the A.M.

Zhou’s drone flew to a height approximately 4,939 feet, or approximately just shy of 1 mile, and 1.8 miles into base, beyond the required line of sight for an operator. Federal officials say they were alerted to the illegal activity “by a drone detection system employed by VSFB Security Forces and a drone detection system employed by the FBI.” It’s not known if the systems detected illegal activity before Nov. 30, but that seems likely due to abrupt changes to webcast procedures for SpaceX launches from the West Coast. The Nov. 23 launch marked the first with unexplained changes to the live webcast. The Nov. 30 and Dec. 4 missions also lacked full webcasts without explanation. At the same time, SpaceX launches from Florida continued without changes to the live webcast practices. Zhou was in the United States on an immigrant visa, and was arrested at San Francisco International Airport. Tagged:
