Southern California, March 1963March 1963

On March 6, 1963, military pilots over Southern California spotted a bright, star-like object moving across the sky in a way that puzzled investigators. Two T-33 training aircraft and an F-101 jet interceptor reported seeing the same object over the course of about an hour, between 1730 and 1843 (5:30 and 6:43 p.m.) local time. The sighting took place in the airspace between Ventura and Santa Barbara, with the object appearing high in a clear blue sky.

The F-101 pilot described a silver object roughly the size of a pea, bright white like a star, with no contrails or exhaust. The object appeared at roughly 80 degrees elevation (high in the sky) and at about 10 degrees off the pilot's left wing. When the F-101 crew turned to intercept, the object seemed to race ahead of them. The pilots estimated the object was flying at 500 knots and was at approximately 100,000 feet altitude, roughly 50,000 feet above their own aircraft. The object vanished instantaneously to the east, described as if a lightbulb had been switched off. A T-33 pilot near Vandenberg Air Force Base also saw a bright light that disappeared suddenly. Multiple observers from Santa Barbara, Vandenberg, and Oxnard reported similar sightings.

Investigators checked what was actually in the sky that day. A weather balloon launched by a training crew at Point Mugu Naval Base had reached 70,000 feet. More significantly, Point Mugu had conducted a high-altitude test at 1047Z (around 2:47 a.m. in local time) releasing a balloon carrying a metallic parachute and chaff (reflective strips used in radar countermeasures) to an altitude of 230,000 feet. The investigators noted that this parachute-equipped balloon drifted southwest over Southern California during the time of the sightings. They also observed that the wind patterns at 80,000 feet were from the west-southwest, which would be consistent with the object moving from east to west as described. However, they noted it would be unusual for a free balloon to move from east to west given the prevailing wind direction.

The reporting officer at Vandenberg could not offer an explanation for the sighting. The file notes that the wind speed and temperature variance at 80,000 feet could be a factor. Despite the proximity of Point Mugu's chaff release test and its timing, the case file does not definitively conclude what the pilots saw. The full case file, comprising 12 pages, is reproduced below as held by the National Archives.
