Robert Jacobs
Robert "Bob" Jacobs is a former US Air Force Lieutenant who commanded a 100-man optical instrumentation unit at Vandenberg Air Force Base, California, in the early 1960s. He is best known for filming a disc-shaped UFO interacting with a dummy nuclear warhead during a September 1964 ICBM test — the Vandenberg Air Force Base UFO Film Incident — and for subsequently being ordered to silence by the Air Force. Jacobs is among the most credible military UFO witnesses on record, as his account was independently corroborated in writing by his superior officer, Major Florence J. Mansman, and he later testified under oath before AARO.

The 1964 Big Sur Incident
Jacobs served as commanding officer of optical instrumentation at Vandenberg, responsible for photographing every nuclear payload and ballistic missile launch from the Western Test Range near Big Sur, California. His unit's 180-inch lenses and telescopes were sensitive enough to image a missile from 160 miles away. On September 14, 1964, his team filmed the launch of a dummy ICBM warhead — a three-stage rocket test designed so that chaff countermeasures would separate from the warhead to deceive Soviet air defenses into targeting the decoy rather than the actual payload.
The launch proceeded normally through all three powered flight stages. At the moment of warhead separation, an unidentified object entered the camera frame. Jacobs described it as traveling at the warhead's speed of approximately 6,000–8,000 miles per hour at the fringe of space, in polar orbit. The craft's shape was that of a classic flying saucer — two saucers pressed together with a rounded hemisphere on top that Jacobs compared to "half of a ping-pong ball." The directed energy beam emanated from this dome. In sequence, the craft fired four beams of light at the dummy warhead, one from each of four approach angles (top, then a second pass, then below, then a final pass), before departing in the same direction it had entered. The warhead fell out of the frame.
Suppression and Disclosure
Within a day or two of the test, Jacobs was summoned to the office of his commanding officer, Major Mansman, who had convened with three men in gray suits later identified as the Director of the Office of the Chief Scientist and two government agents. After a private screening of the film, Mansman ordered Jacobs to attribute the beam of light to "Laser Tracking Strikes" — a cover story that Jacobs noted was factually impossible, as lasers were still in their infancy in 1964 and were not deployed for tracking purposes. Mansman warned of "dark consequences" for any breach. The agents then cut the UFO footage from the reel with scissors, placed it in a briefcase, and took it. Jacobs was handed the edited film.
Jacobs maintained silence for 18 years. He later reasoned that since he had never signed a confidentiality agreement and was never told the incident was formally classified, he was within his rights to speak. He disclosed the incident publicly in 1982 and faced immediate reprisals — sustained harassing phone calls through the night telling him "you're going down." The case was published in MUFON's journal in January 1989.
Major Mansman subsequently confirmed Jacobs's account in a signed letter to Paramount Pictures during production of a documentary on the case, describing the incident as "absolute fact."
Congressional Testimony
Jacobs testified under oath to AARO and Sean Kirkpatrick on February 10, 2023, bringing the incident into the formal record of contemporary UAP investigation — directly contradicting AARO's public position that no credible nuclear-related UFO cases existed.
Significance
Jacobs's case stands out within the UFO Interference with Nuclear Weapons pattern for several reasons: it involves physical film evidence (subsequently destroyed or concealed), direct corroboration from his commanding officer, a detailed craft description consistent with other classic disc sightings, and a documented suppression effort by government agents. It is cited as one of the primary cases illustrating that UFOs appear capable of interacting with nuclear weapons delivery systems in a targeted, controlled manner.
The craft's physical description — two discs with a hemisphere dome — closely matches accounts in the Flyby Footage case and the McMinnville Photos, a cross-case consistency cited by researchers as supportive of a consistent saucer morphology across independent sightings.
