Category 1, Distant Encounters
Preliminary Rating: 5
Classification of Distant Encounter is usually
an incident involving an object more than 500
feet from the witness. At night it is
classified as a "nocturnal light" (NL) and
during the day as a "daylight disc" (DD). The
size of the object or the viewing conditions
may render the object in greater detail but
yet not qualify the sighting as a Close
Encounter which is an object within
March 8, 1957; Between Mockville and Arrity, North Carolina (BB)
At 12:00 a.m. EST, a civilian observed an object 30 to 35 feet long with a round nose that was 10 to 12 feet in diameter. It was gray-white in color and the nose was a very bright green light. The object was at an altitude estimated at 500 to 2000 feet and traveled from the NW, circled then moved to the NE. The length of the observation was 2 minutes. (Here is another report from the SE U.S. This one was carring a very bright green light in the nose. The next day on March 9, 1957, there were three sightings of green fireball-like objects from aircraft in the SE U.S. area all at different times, so there is no overlap here).
Written off by Blue Book as possible jet aircraft with afterburner. However, the description doesn't fit and the witness heard no sound.
