Len Kasten

1934–2026Researcher, American

UFO researcher and author who documented 30+ years of extraterrestrial contact evidence and classified military programs

Background

Len Kasten (1934–2026) was an American UFO researcher, freelance writer, and leading chronicler of extraterrestrial contact and hidden military aerospace programs. With over thirty years of intensive investigation into alien-human interaction, classified technology, and historical UAP documentation, Kasten authored four major works that synthesized interviews with prominent UFO figures, military insiders, and abduction researchers into comprehensive narratives of off-world contact and government concealment.

Personal Encounter

Kasten's engagement with UFO phenomena began with a direct observation near Eglin Air Force Base on the Florida Gulf Coast, where he witnessed a luminescent green and gold craft moving swiftly and silently across the water. The sighting was independently corroborated the following day by radar operators at the base and reported through military channels, lending credibility to the event and catalyzing his decades-long research commitment.

Research & Publications

Kasten earned a B.A. in Liberal Arts from Cornell University and an M.F.A. from National University. He served as a former member of both NICAP (National Investigations Committee on Aerial Phenomena) and MUFON (Mutual UFO Network), and held the presidency of the American Philosopher Society.

His published output included over fifty feature articles for Atlantis Rising magazine, New Dawn magazine, and other scholarly outlets, along with ten cover stories. His four monographs established him as a prominent voice in UFO studies:

  • The Secret History of Extraterrestrials: Advanced Technology and the Coming New Race (2010, Inner Traditions) — Kasten's foundational work, featuring extended interviews with John Mack, Jesse Marcel, physicist Paul LaViolette, Egyptologist Robert Bauval, and exopolitician Michael Salla. Synthesizes abduction accounts, anti-gravity device evidence, hybrid breeding programs, and government suppression timelines.

  • Secret Journey to Planet Serpo: A True Story of Interplanetary Travel (2013) — Kasten's investigation into the alleged Zeta Reticuli exchange program: a classified 1964 U.S. government agreement with extraterrestrials resulting in a twelve-person military delegation departing Earth in 1965 for a ten-year mission to the planet Serpo, with seven returning in 1978.

  • Alien World Order: The Reptilian Plan to Divide and Conquer the Human Race (2017) — Documents reptilian-driven agendas, interbreeding initiatives, and hidden hierarchies within global governance.

  • Dark Fleet: The Secret Nazi Space Program and the Battle for the Solar System — Explores documented post-WWII Nazi aerospace continuity, underground Antarctic bases, and alleged extraterrestrial technology transfer.

Media & Outreach

Kasten was interviewed on over forty radio programs, including four appearances on Coast-to-Coast AM with George Noory and two on Fade to Black with Jimmy Church, bringing his research to millions of listeners seeking disclosure of hidden UAP history and contact narratives.

Significance

Kasten's work bridged academic rigor (Ivy League education, peer-reviewed contributors) with grassroots UFO investigation networks (NICAP, MUFON), positioning him as a trusted synthesizer of classified accounts, eyewitness testimony, and historical documentation. His books remain standard references in disclosure and exopolitical research communities, cited for their systematic presentation of contact evidence, military testimony, and alternative historical timelines.
