When builders of the Coronado Naval Amphibious Base in San Diego planned this complex in 1967, satellite imagery was probably the furthest thing from their minds. But in 2007, Google Earth sleuths found that four unconnected buildings on the base formed an unfortunate shape when viewed from above: a swastika. The Navy says it's spending more than $600,000 to mask the shape. "We don't want to be associated with something as symbolic and hateful as a swastika," a spokesman said.
