🇺🇸 USAF — Project Blue Book
A 16-year-old civilian reported seeing a round object the size of a dime in the sky over Glen Avon, California, in the early 1950s. The object appeared and disappeared at the same point, leaving a small red and white trail. The witness was alerted by the noise of an aircraft. The sighting lasted 30 seconds and no photos were taken. The report suggests it could be an aircraft, but other possibilities are not ruled out.
The official report classifies the observation as "possibly an aircraft," without reaching a definitive conclusion. The teenager's testimony, though brief, includes details such as size, color, and trajectory of the object. Despite the lack of photographic evidence, the case was documented and analyzed by military personnel. The ambiguity of the report reflects the difficulty of identifying non-conventional aerial objects with the available data at that time.
