What lies beyond the familiar stories of Area 51—and why has the alleged facility known as S4 remained one of the most enduring mysteries in UFO history?
Join Colorado MUFON on Saturday, August 8, 2026, for a special presentation by longtime MUFON leader, researcher, and investigator Ken St. John. Drawing upon his extensive technical background, aviation experience, government contracting work, and decades of involvement in UFO research, Ken will explore the history, claims, and continuing questions surrounding S4.
Often described as a highly restricted installation located near Area 51, S4 has become synonymous with allegations of classified aerospace programs, concealed technology, underground facilities, and government knowledge of unidentified craft. Ken will examine the subject through the perspective of an experienced researcher—separating documented information from speculation while considering the testimony, locations, technologies, and secrecy that have kept S4 at the center of the disclosure debate.
Ken St. John is a longtime member and benefactor of MUFON International. He formerly served as MUFON International’s Chief Operating Officer, Chief Information Officer, Director of Training, and a member of its Board of Directors. He holds degrees in Physics, Mathematics, and Electronic Engineering.
A retired commercial pilot and flight instructor, Ken has also served with the FAA as an Accident Prevention Specialist. His professional experience includes work as a private contractor for the Department of Defense and private-sector assignments throughout Southeast Asia and Europe. Ken is also a longtime member of Colorado MUFON, a former member of its Board, and a familiar guest who has presented to COMUFON audiences for more than 12 years.
Whether you are deeply familiar with the S4 story or are encountering it for the first time, this presentation offers a rare opportunity to explore one of the most controversial and compelling subjects in modern UFO research.
