UFO sighted in Tehran in 1959

Summary

In April 1959, a report from Project 10073 recorded a sighting in Tehran, Iran. Although the document is partially illegible, it mentions a ground-based visual observation. The data suggest the object was seen for a short period, and no photos were taken. The lack of clear information hindered a definitive evaluation of the phenomenon.

The conclusions point to possible explanations such as a balloon, an aircraft, or an astronomical event. However, the lack of sufficient data prevented a clear resolution. This case reflects the common ambiguity in many reports from that era, where technology and records were not precise enough to confirm or rule out hypotheses with certainty.
