PROJECT BLUE BOOK - The CIA and Government conspiracy to hide Top Secret UFO Files. This Edition 1 was updated April 2021. As of 2017 the U.S. Government began releasing UFO images (videos) taken from Navy F-18 fighter jets.From 1947 to 1969, the U.S. Air Force recorded a total of 12,618 UFO sightings. The investigation of these "Unidentified Flying Objects" was headquartered at Wright-Patterson Air Force Base, Ohio. In this book we address the declassified Project Blue Book cases as well as sensational UFO encounters that remain classified (not included in the Project Blue Book files). The chapters in this book are arranged by topic based on the way UFOs operate. Each chapter contains chronologically ordered short stories of UFO case files.Project Blue Book was just one of many UFO reporting channels for the U.S. Government. Blue Book does not contain all UFO record sightings. Many military UFO sightings remain classified "Top Secret" today. This book explores declassified cases as well as a few non- declassified cases. "Project Blue Book: Top Secret UFO Files" is prepared to tell you the truth about the extraterrestrial's visitors monitoring our military bases and following commercial and military passenger planes. This book is a culmination of many hours researching thousands of declassified military UFO records, newspaper articles, and other sources. Through 27 chapters we discuss many topics including the various forms of evidence (e.g., physical, radar and visual); actual military and civilian UFO case histories. The stories are compelling and include the typical "cat and mouse" games used by the Alien pilots to evade our jets. On the one hand, our police and military jets chase the UFOs. On the other hand, UFOs pursue our military and commercial passenger planes.You will come away understanding the reasons why they are here, what they are doing, and the ships they use. Finally, you will also understand which agencies (CIA, FBI, etc.) and congressional members wanted the UFO phenomenon to remain "classified" as a result of losing pilots and planes during aerial engagements.
