Unidentified Aerial Phenomena
Funny enough I was just reading the book &quot;In Plain Sight&quot; [1] before I flipped over to hacker news. It&#x27;s a book about the serious investigation into UAPs by various governments, and is heavily sourced, with often times a half dozen references per page, many official and declassified sources.  It&#x27;s hard to come out of reading it without being strongly convinced that these UAP are not of human or natural origin.<p>[1] <a href="https:&#x2F;&#x2F;www.goodreads.com&#x2F;en&#x2F;book&#x2F;show&#x2F;57734614" rel="nofollow">https:&#x2F;&#x2F;www.goodreads.com&#x2F;en&#x2F;book&#x2F;show&#x2F;57734614</a><p>Edit: really curious if any of the downvoters could mention their rationale.
