My not-so-secret guilty pleasures: UFO books. This current read is an excellent biography of J. Allen Hynek, the scientific maverick first tasked by the US Air Force to sort it all out. It presents a puzzle, though. In the 1950s and 60s these glowing things literally stopped cars: knocking out ignitions, turning off headlights and radios, etc. But it doesn‘t seem to happen nowadays. So what changed? The UFOs, the cars, or something else?
