My favorite book on the subject is...
UFOs: Generals, Pilots, and Government Officials Go On The Record by Leslie Kean.
I would say this is hands down one of the best books ever written on the subject.
Only the best cases, with hard evidence and multiple witness reports. Speculation is kept at a low. I always believed in UFOs before this book, but
after I read it, it became laughably obvious how real the phenomenon is.
