Triangular UFO sighted over Greenbay in 1957

Summary

In October 1957, a witness in Greenbay, Wisconsin, observed two triangular objects in red, white, and blue colors, roughly the size of a star. The sighting occurred in the early hours of the morning and lasted about 10 minutes. Although the witness used binoculars, the exact formation and nature of the objects could not be determined due to a lack of key information. The official report concluded that there was insufficient data to evaluate the case.

The testimony was submitted to Project 10073, a U.S. Air Force initiative to investigate unidentified aerial phenomena. However, essential elements such as speed, altitude, or behavior of the objects were not provided, making any conclusive analysis difficult. Like many other cases from that era, this one remains unsolved, adding a touch of mystery to the history of UFO sightings in the 1950s.
