Big Sur Incident

Date: September 15, 1964
Location: Vandenberg Air Force Base, California
Appearance: Disc with dome on top
Classification: CE 2
Sources: Dr. Bob Jacobs; Dr. Florenz Mansmann
Summary: UFO shoots down dummy nuclear warhead

An Atlas D Intercontinental Ballistic Missile (ICBM) was launched from Vandenberg Air Force Base, California, carrying an experimental enemy radar–defeating system and dummy nuclear warhead. A disc-shaped UFO approached the missile which was flying at 11 thousand miles an hour.

UFO shoots at missile As the UFO chased and then circled the warhead, four bright flashes of light emanated from the unknown craft. Four times, from the center of the flashes there was a luminous beam, or bolt, extending all the way from the UFO to the warhead. Then the UFO flies out the way it came in. The warhead malfunctioned and tumbled out of orbit, hundreds of miles short of its target.

USAF officer Lt. (now Dr.) Bob Jacobs was tasked with filming the Atlas launch through a high-powered telescope and states that the entire encounter was captured on motion picture film. According to Jacobs, while the UFO’s maneuvers were readily discernable, other minute details - including the object’s domed disc-shape - were only discovered during in-depth optical analysis conducted at Vandenberg.

Jacobs’s account, relating to both the UFO incident itself and the subsequent cover-up, has been entirely endorsed by another officer, retired Maj. (later Dr.) Florenz Mansmann. In 1987, Mansmann stated that the film was confiscated by CIA agents.

Ongoing UFO activity at U.S. nuclear weapons sites is a documented historical fact. Declassified Air Force, FBI, and CIA records have revealed unquestionably significant incidents. On some occasions, the reported UFO activity involved interference with the missiles' functionality. Dramatic testimony to this effect has come from ICBM launch and targeting officers, as well as missile maintenance personnel.


  • What was filmed that September day in 1964 was a solid, three-dimensional, intelligently controlled flying device.
  • It emitted a beam of energy, possibly a plasma beam, at the dummy warhead and caused a malfunction.
  • This "craft" was not anything of which our science and technology in 1964 was capable.
  • The flashing strikes of light that were recorded on film were not from laser tracking devices. Such devices did not exist then aside from small scale, laboratory models.
