What Happened at Area 51? [PDF ebook] 

Area 51 is a military base located in Nevada, though it has some questionable lore attached to its reputation. It’s said to be the site of alien dissections, clandestine aircraft testing, and numerous covert government programs. The US government denied for many years that it even existed, which didn’t stifle any of the rumors. This engrossing book presents what is known about the facility, the declassified projects that have taken place there, and the questions that still have to be answered about one of the military’s most secretive locations.
