On June 5, 1952, the U.S. government conducted its final atom bomb test at Nevada’s Yucca Flat, 300-miles from Los Angeles. A brief ‘aurora borealis’ lit up the night sky making it possible to see downtown Los Angeles.
On March 12, 1955, at 5:20 a.m., the government detonated another atomic bomb in the Nevada desert. Once again, the blast eerily lit up the Los Angeles skyline. Here is the 9th Street cutoff at the Harbor Freeway. (LAPL 00058252)
