"The Interupted Journey", the story of Betty and Barney Hill was the first book I read decades ago about UFOs. I remember as a kid, walking home after dark from basketball practice wondering if I might have "missing time" once I got home.
Shortly after I read it we had a UFO "flap" in my area with a lot of sightings. I figured it was just a matter of time when saucers would be landing on the White House lawn.
