CROSS KEY DORADO's video: UFO Rocket launch

A short time after its appearance, multiple local law enforcement agencies confirmed the flash of light was from the rocket launch, which blasted off from Vandenberg Air Force Base along California's Central Coast. Vandenberg Air Force Base announced earlier this week the launch was set for 5:27 p.m. Friday from Space Launch Complex-4. The base said it was the “fourth Iridium mission consisting of 10 satellites on a SpaceX Falcon 9 rocket.” Space Launch Complex-4 is along the Pacific Ocean coast west of Lompoc in Santa Barbara County, about 140 miles west-northwest of downtown Los Angeles. The SpaceX launch was the final scheduled one out of Vandenberg this year, and officials deemed it a success. KTLA's Melissa Pamer contributed to this story.
