UFO sighted near ECHO I satellite in 1963

Summary

In September 1963, an aerial observer reported an unidentified object near the Pacific Ocean. The sighting occurred between 15:15 and 15:30 UTC at the precise location of 43.20°N 173.50°W. The object was moving rapidly eastbound and remained visible for 15 minutes. Although no photos were taken, the data matched the trajectory of the ECHO I satellite, which was in orbit at the time. The official conclusion was that the sighting corresponded to this satellite, suggesting the report was part of an effort to explain unknown aerial phenomena with available scientific data.

The report, classified under Project 10073, includes precise coordinates, times, and directions. It mentions that the ECHO I satellite crossed the equator at 1427 and that its trajectory took it southward. This placed the satellite in the region where the sighting was recorded. Despite the observer being unable to determine the exact altitude of the object, the satellite's orbital data matched the event description. The analysis concluded it was not a balloon, aircraft, or astronomical phenomenon, but the ECHO I satellite. This type of report was common during the Cold War, when UFO sightings were frequent and often linked to ongoing space projects.
