UFO sighted over Springfield in 1957

Summary

In January 1957, a witness in Springfield, Massachusetts, observed a circular and flat object glowing in the dark. The object moved in a straight line at high speed for 15 minutes before disappearing on the horizon. Although initially considered a balloon or astronomical phenomenon, investigators concluded it was likely an aircraft. The responsible officer noted there was extensive air activity in the area, supporting the theory it could have been a military aircraft with landing lights visible.

The report, though brief, highlights the impossibility of identifying the object as a meteor due to its trajectory and duration. Additionally, it mentions the possibility that it was a jet exhaust trail seen at high altitude. Despite the lack of photographs or radar data, the testimony of the sole witness and the context of air activity suggest a conventional explanation, although other possibilities are not ruled out.
