Philip J. Corso

Philip J. Corso (1915-1998) was an American Army officer who claimed involvement in U.S. government UFO programs. Serving as a Lt. Colonel, he alleged working on President Eisenhower's National Security Council, advising on Roswell, UFOs, and extraterrestrial biological entities (EBEs). From 1957-1961, Corso headed the Army's Foreign Technology Desk in R&D under General Arthur Trudeau, claiming he distributed Roswell crash artifacts to contractors, seeding technologies like integrated circuits, fiber optics, night vision, lasers, and Kevlar. He purportedly saw an extraterrestrial body at Fort Riley in 1947. His key publication, 'The Day After Roswell' (1997, ghostwritten by William J. Birnes), became a New York Times bestseller but faced criticism for factual errors, chronological impossibilities, and skepticism from analysts like Philip J. Klass, who questioned his qualifications and claims.
