On June 1, 1978, during the second day of bootcamp for the U.S. Marine Corps, Michael Christopher Gerloff was asked whether he wanted to go to space and serve in a “20 and back” program. He recalls everything that subsequently happened during the intake process for his recruitment into the “Space Marines”, and has partial recall of his subsequent activities during his 20 and back service. After ending active reserve service with the USMC Reserves (1978-1984), Gerloff went on to serve as a U.S. Army Ranger (1987-1991), and police officer with the Mountlake Terrace and Seattle Police departments (1992-2001). From 2004-2005, he served as an international police officer with the United Nations Liberia peacekeeping mission. Gerloff has provided military and police records that corroborate key aspects of his testimony, and contain many anomalies which point to his “20 and back” service. He believes that his coming forward has been sanctioned by a USMC/Department of Navy intelligence group established by President Dwight Eisenhower, which is actively promoting disclosure of a US Navy Secret Space Program. In Part 1 of this five part interview series, Gerloff describes a huge triangle UFO sighting that triggered him, only four days later, to begin the process of joining the U.S. Marine Corps. He describes how a USMC captain interviewed him during his initial testing at bootcamp, and alluded to the triangle sighting as a factor in him receiving a special offer. The captain made an offer to Gerloff to join a “20 and back” Space Program. The captain said that he would send a telegram to Gerloff’s parents. In 2016, Gerloff saw the telegram, a “Marsgram”, for the first time and it triggered more memory recall. The Marsgram is among the documentary evidence supplied by Gerloff in support of his claim of being covertly recruitment into a “20 and back” secret space program run by the US Navy.
