More than half a century since Roswell, UFOs have been making headlines once again. On December 17, 2017, the New York Times ran a front-page story about an approximately five-year Pentagon program called the Advanced Aerospace Threat Identification Program. The article hinted, and its sources clearly said in subsequent television interviews, that some of the ships in question couldn't be linked to any country. The implication, of course, was that they might be linked to other solar systems. The UFO community-those who had been thinking about, seeing, and analyzing supposed flying saucers (or triangles or chevrons) for years-was surprisingly skeptical of the revelation. Their incredulity and doubt rippled across the internet. Many of the people most invested in UFO reality weren't really buying it. And as Sarah Scoles did her own digging, she ventured to dark, conspiracy-filled corners of the internet, to a former paranormal research center in Utah, and to the hallways of the Pentagon. In They Are Already Here we meet the bigwigs, the scrappy upstarts, the field investigators, the rational people, and the unhinged kooks of this sprawling community. How do they interact with each other? How do they interact with "anomalous phenomena"? And how do they (as any group must) reflect the politics and culture of the larger world around them?
