Project 10073 Record Card and Naval Messages — Guam, November 1961

This document collection details an Unidentified Flying Object (UFO) sighting that occurred over Guam on November 11, 1961. The primary report, filed under Project 10073, describes an incident at 0900Z involving a single object observed by five mature observers at four different points on the island. The object was described as pear-shaped, greenish-whitish in color, and occasionally displaying bluish and reddish hues. It was noted to have a white front and a green rear, moving in a horizontal, westerly flight path at great speed before disappearing instantaneously after approximately 30 seconds. A separate, corrected naval message clarifies that an Air Force enlisted weather observer at Andersen Air Force Base, considered a reliable witness, sighted a round, blue-green object directly overhead at 11144Z. This witness reported the object moved in a straight northeasterly course at great speed, changing color to blue-green, and disappearing 20 degrees above the horizon after a duration of three seconds. The witness estimated the size of the object to be that of a dime held at arm's length. Both reports emphasize that there was no sound and no known aircraft in the vicinity. Weather conditions at the time were reported as clear with some cloud cover. The official conclusion recorded on the Project 10073 record card categorizes the sighting as a 'fireball observation,' noting that the object exhibited characteristics consistent with such phenomena.
