It is the most famous military installation in the world. And it doesn't exist. Located a mere seventy-five miles outside of Las Vegas in Nevada's desert, the base has never been acknowledged by the U.S. government — but Area 51 has captivated imaginations for decades. Myths and hypotheses about Area 51 have long abounded, thanks to the intense secrecy enveloping it. Some claim it is home to aliens, underground tunnel systems, and nuclear facilities. Others believe that the lunar landing itself was filmed there. The prevalence of these rumors stems from the fact that no credible insider has ever divulged the truth about his time inside the base. Until now. Annie Jacobsen had exclusive access to nineteen men who served the base proudly and secretly for decades and are now aged 75-92, and unprecedented access to fifty-five additional military and intelligence personnel, scientists, pilots, and engineers linked to the secret base, thirty-two of whom lived and worked there for extended periods. In Area 51, Jacobsen shows us what has really gone on in the Nevada desert, from testing nuclear weapons to building super-secret, supersonic jets to pursuing the War on Terror.
