UFO sighted in the Pacific in 1943

Summary

A Project 10073 record describes a 1943 sighting of an unidentified object in the Pacific. A ground observer reported seeing a satellite that shone like a first-magnitude star, moving west to east at 15 degrees above the horizon. Although no photos were taken, the report concluded the object was not a balloon, aircraft, or astronomical phenomenon. Instead, it was labeled as "ECHO I," a category suggesting an unconventional event. The calculated speed of the object was 30 degrees of arc in 10 minutes, indicating rapid movement. The report was distributed to multiple military and intelligence agencies, including the CIA, highlighting its significance.

The report also includes hydrological data from 1962, though they are not directly related to the UFO sighting. These data appear to be tables of measurements with coordinates and numerical values, possibly related to ocean currents or suspended particles. Despite the lack of direct connection, their inclusion in the same document suggests it was a classified file with multiple data entries.
