New Lenox, Illinois: Teenager watches two green lights move back and forth in the south

Around 10:00 p.m., a teenager in New Lenox, Illinois, saw two green light sources from his bedroom window. They moved back and forth in the southern sky and disappeared briefly when a plane flew below them. The sighting was reported in IUR/Frontiers of Science under the title 'UFOs—or IFOs over Joliet?'. The account follows the entry in George M. Eberhart's chronology UFOs and Intelligence (CUFOS) and the sources cited there; it is not an independent determination by From Beyond Space.
