UFO Sighting in Bethlehem, Pennsylvania on 2017-11-24 17:35:00 – Travelling south route 512, saw object descend east to west very fast, became 3 objects before disappearing

My brother and i were traveling south in lehigh valley area, and noticed an extremely fast object descending from east to west. much faster than any normal plane or helicopter. duration was about 3-4 seconds. the distance it covered was about three quarters of the windshield, left(east) to right(west), if that makes sense. the object appeared to "break up" into three lights before disappearing altogether.
