Last month, journalist Leslie Kean revealed shocking testimonials from government officials about unexplained behavior by unknown objects in the sky over many decades.
Kean's book, the New York Times bestseller "UFOs: Generals, Pilots and Government Officials Go On the Record" includes a foreword by John Podesta and first-person accounts written by over a dozen military and aviation witnesses and official investigators from around the world.
A Huffington Post slide show from last month provides useful background for this batch of new information, which focuses on original witness drawings, and the importance they play in UFO investigations, particularly when similar features are depicted in different locations and at different times.
What do you think about the credibility of the accounts? And what, if anything, have you seen?
