Unidentified Aerial Object with Green Trail over National City

Summary

In August 1966, a witness in National City, California, reported an unidentified aerial object with a ship-like shape and a blue-green ionization trail. The object was seen for a few seconds while descending toward the desert, giving the impression it might land. The report notes that the object appeared vaporous and bright, with a trajectory resembling that of retro rockets. Despite the detailed description, authorities requested more information for evaluation, as the initial data was insufficient.

The case was analyzed under Project 10073, and while it was considered possibly astronomical in nature, the possibility of an unidentified object was not ruled out. The witness cooperated with authorities, but the final report concluded without a definitive explanation.
