Oval objects seen by moonlight reflection

Summary

A UFO sighting from September 1955 in Massachusetts describes two oval-shaped objects traveling in a straight line at an estimated altitude of 15,000 to 17,000 feet. The objects were only visible by the reflection of moonlight, which limited direct observation. The witness initially thought they were jet aircraft, leading authorities to consider the possibility of a conventional aircraft.

Although the sighting was reported over a month later, the available data suggest it was not an astronomical event or a balloon. The lack of photographs and the reliance on moonlight reflection for visual observation add an air of mystery to this case, which remains without a conclusive explanation.
