UFO sighted near Sioux City in 1967

Summary

In May 1967, a witness in Sioux City, Iowa, reported an unidentified aerial object that remained stationary in the sky for about four minutes. The object was described as round with a dome on top and a flat surface on the bottom. It was estimated to be about 22 feet tall and emitted a bright green light. Despite the detailed description, authorities could not identify the phenomenon.

The witness, a housewife and part-time college student, described the object as reliable and well-detailed. The official U.S. Air Force report concluded there was no clear explanation for the phenomenon. The witness was asked to complete an additional form for more details, but no definitive resolution was found. The case remains one of the many unresolved reports from that era.
