U.S. Intelligence Agencies worked together in 1980, to capture a non-human extraterrestrial. Code-named Operation TANGO-SIERRA, this joint effort took 5 months and approximately 60 intelligence officers, who surveilled and eventually took custody of a “Septeloid” (originating from the 4th planet in the star system Delta Pavonis, located 20 light-years from Earth).
The then President Jimmy Carter ordered the release of this non-human ET, who had been working as a government employee. After his release the alien then disappeared, presumably back to his home world.
“According to accounts released Saturday, April 24, 2010, by the coordinator of an e-mail news and information service, officials of the U.S. Defense Intelligence Agency (DIA), U.S. Air Force Office of Special Investigations (AFOSI) and other U.S. government agencies have been involved in security activities involving human-appearing extraterrestrial beings in the U.S.”
