“According to the Jacobs/Mansmann account as presented by Hastings, the object circled the dummy warhead and four bright flashes appeared to emanate from it; the warhead then fell out of its planned trajectory. Hastings notes that the case is disputed and devotes substantial space to skeptical counterarguments.”

“Hastings challenges Kingston George’s September 22 launch identification and cites Vandenberg launch records summarized by Encyclopedia Astronautica: a September 15, 1964 Atlas D mission was an ABRES LORV-3 re-entry-vehicle test and matched one of the dates in Jacobs’s personal records, whereas the September 22 mission had a different published purpose.”

CLAIM-710038reported
“Faded Giant summarizes Robert Jacobs's account that a special telescopic camera at Big Sur filmed an Atlas test in 1964 and that subsequent film review showed a disc-like object approach the separated dummy warhead, maneuver around it and emit apparent beams before leaving the frame.”

“The book states that Jacobs placed the event in September or possibly November 1964 and that Florenz J. Mansmann later corroborated the account in writing. The source therefore preserves date uncertainty rather than establishing an exact launch date.”
