A former US Army sergeant who alleged he helped cover up evidence of extraterrestrial life has spoken about a lifelong telepathic relationship with a mantis-like alien named Korona. Clifford Stone, who died in 2021, claimed that his first interaction with the entity occurred in his childhood and continued until his death.
Stone testified before the Washington National Press Club in 2001 about his alleged involvement in a secret army program tasked with recovering materials from UFO crash sites. He stated that he participated in retrievals of crashed saucers, some of which contained live extraterrestrials. However, no government body has confirmed these claims.
The mantis-like alien described by Stone matches reports of 'Insectoid' extraterrestrials, one of four categories outlined by Dr Hal Puthoff, a physicist who worked on a CIA UFO research program. The categories include Grays, Nordics, Reptilians, and Insectoids, to which Korona belongs.
Stone said Korona could feel his emotions and that the alien was among many walking among humans to understand what it means to be human. Despite his extraordinary claims, Stone's army records show he primarily performed clerical administrative work, which he said was a cover for his real duties.
