Vandenberg Minuteman-Silo Hover Report
February 1967, 99% certain according to Leroy Clark; exact silo designation not rememberedVandenberg AFB north missile-test area, California, California, United States
Leroy Clark told Hastings that coworkers returning from night survey work relayed a report of a bright, silent object approaching from the Pacific and hovering approximately 50–100 feet over a Minuteman silo. Clark did not see the object himself and could not determine whether the missile schedule or functionality was affected.
