Springfield, Pennsylvania: Domed object with rotating window band passes 20 feet over yard

At 7:45 p.m. on April 24, 1962, Alice W. Gasslein and her mother, Estelle W. Wilkinson, were driving near their home in Springfield, Delaware County, Pennsylvania, when they saw a large domed object emitting flashes of green light moving over the roofs of nearby homes. A rotating band around the main body consisted of a series of square windows from which came shafts of bright white light. They drove home to alert Alice's husband, Joseph A. Gasslein, an aviation worker at Boeing; by then the object was about half a mile away, giving off colored lights. Around 8:10 p.m. the object returned, flying toward the Gassleins' home south of Walsh Park only 20 feet above ground level, passed over their backyard, made a sharp left turn and moved away to the east. The entry cites Olsen's case compilation, an IUR retrospective of 1985 and Loren E. Gross's history for January–June 1962. 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.
