Project Sigma

An ongoing 1954 Top Secret project that looked into how to communicate with aliens. That projects existence was revealed in the PROJECT AQUARIUS Briefing Document and is said to have succeeded in 1964 when a USAF intelligence officer met two other aliens at a prearranged location in a desert in New Mexico. However, there is a "Project Sigma" listed in the 1986 Defense Marketing Services Code Name Directory as a "Top Secret Air Force program involving Rockwell International" and has been officially identified as a laser weapons project.
