1949 UFO in Pennsylvania and Ohio

Summary

A declassified document from June 26, 1949, describes an aerial phenomenon observed in Pennsylvania and Ohio. A witness, accompanied by experts like the director of the Flower Observatory and the executive director of the American Institute of Architects, saw a luminous object that appeared as a "blue-green moon." The object, estimated to be between half and two-thirds the size of the moon, moved rapidly to the south without emitting sound or leaving a luminous trail. Despite its impressive size, no explosive effects or sounds were recorded, causing some confusion among observers. The detailed description of the event, including its trajectory, color, and duration, led astronomers to classify it as a "fireball."

The report, part of Project 10073, includes testimonies from multiple sources, including a letter from the main witness to the Franklin Institute. It highlights observations from other individuals and the lack of physical evidence, reinforcing the hypothesis of an astronomical phenomenon. The document also notes the absence of sound or luminous trail, characteristics that distinguished it from typical meteors. Although considered a fireball, the unusual nature of the event generated interest and analysis from meteor experts and astronomers.
