More than two million people have signed up during the past two months to converge on Area 51, the air base near Rachel, Nevada, with hopes of seeing aliens. Although the organizer has called the âStorm Area 51" event a hoax, city officials estimate that 30,000 to 40,000 people could show up this weekend. Each year, Area 51âs mythology draws tourists from around the world. People come to catch a glimpse of otherworldly aircrafts and the mysterious base, which may house foreign spacecrafts.
