In August 1951, a V-shaped formation of lights was seen over the city. The "Lubbock Lights" series of sightings received national publicity and is regarded as one of the first great "UFO" cases. The sightings were considered credible because they were witnessed by several respected science professors at Texas Technological College and were photographed by a Texas Tech student. The photographs were reprinted nationwide in newspapers and in "Life". Project Blue Book, the USAF's official investigation of the UFO mystery, concluded the photographs were not a hoax and showed genuine objects, but dismissed the UFOs as being either "night-flying moths" or a type of bird called a plover reflected in the nighttime glow of Lubbock's new street lights.
