Westmoreland County UFO Wave

The 1973–1974 Wave

During late 1973 and into 1974, Westmoreland County and surrounding areas of southwestern Pennsylvania experienced one of the most widely reported UFO waves in the region's history. The phenomenon spanned nine counties across an 80-mile area and became known as the "double flap" due to the simultaneous reports of UFO sightings and large, ape-like creature encounters. Unlike many UFO waves that capture brief public attention, this event was systematically documented by a young electronics technician named Stan Gordon, who would become one of the most prolific UFO researchers in Pennsylvania.

The wave occurred during the broader 1973 UFO flap that swept across North America, but the Pennsylvania incidents were particularly notable for their combination of high-credibility witnesses (including law enforcement), reports of electromagnetic vehicle interference, physical ground traces, and close-range encounters with tall humanoid entities.

The October 25, 1973 Primary Incident

The wave's most dramatic event occurred on October 25, 1973, around 10:30 p.m. near Uniontown. Gordon received a call from a state trooper reporting that approximately 15 people had witnessed a massive red spherical object, estimated at over 100 feet in diameter, hovering low over a pasture. Witnesses described the object draining power from nearby vehicles—engines stalled, lights dimmed—suggesting significant electromagnetic effects. The craft emitted a distinctive sound described as a cross between a high-pitched whine and an infant's cry.

Most remarkably, at least two witnesses reported observing tall humanoid figures, each measuring 7–8 feet in height, standing near a fence line at the edge of the field. These entities were visible for several minutes before the main aerial object departed. The combination of the large craft, vehicle electromagnetic interference, and close-range humanoid observation made this encounter one of the most significant multiwitness cases in UFO history.

Documentation and Investigation

Gordon's systematic approach to documenting the wave established a foundation for rigorous UFO research. He founded the Westmoreland County UFO Study Group in 1970 and later expanded it into the Pennsylvania Center For UFO Research in 1975. His archive from the 1973–1974 events and subsequent decades now exceeds 3,000 documented reports spanning low-altitude sightings, structured craft observations, luminous orbs, electromagnetic vehicle interference, animal behavioral anomalies, and physical ground traces.

The wave's credibility was bolstered by eyewitness accounts from multiple independent sources, corroboration by state law enforcement, and detailed field investigation that collected physical and witness evidence before memories faded. However, the concurrent reports of large bipedal creatures—elements typically associated with cryptozoology rather than ufology—added layers of complexity that have prevented mainstream scientific consensus on the phenomenon's nature.

Legacy and Significance

The 1973 Westmoreland County wave remains a benchmark case in UFO documentation, demonstrating how organized, methodical investigation can preserve otherwise ephemeral event data. The incident helped establish Pennsylvania as a region of sustained UFO activity and provided a foundation for decades of continued monitoring by Gordon and other researchers. The combination of mass-sighting credibility, electromagnetic effects, and close humanoid encounters makes the case central to ongoing discussions about the nature, origin, and intent of unidentified aerial phenomena.
