Pennsylvania, one of America's original thirteen colonies and home to the birthplace of American independence, has also witnessed its fair share of unidentified aerial phenomena throughout the modern UFO era. The Keystone State's combination of major metropolitan areas (including Philadelphia, one of America's largest cities), extensive rural countryside, and significant military installations has created diverse conditions for UFO sightings. From the industrial cities of Pittsburgh and Philadelphia to the Amish farmlands of Lancaster County, Pennsylvanians across the spectrum of American life have reported unusual phenomena in the skies above the commonwealth.
The state has a notable history of significant UFO events, including the famous 1973 Codorus case that became one of the most documented UFO incidents in American history. Pennsylvania's position along the densely-populated Eastern Seaboard means that sightings often involve multiple credible witnesses, including reports from law enforcement officers and other trained observers. The state's rich history of manufacturing and industry, combined with its agricultural heritage, has produced a diverse population with varied perspectives on unexplained phenomena.
