On May 24, 1952, Angelucci was driving home from work at an aircraft plant in Burbank, California, when he spotted a red, glowing, oval object. He began to follow it and got within 30 feet of it when it shot out two smaller objects and then streaked away. The smaller objects, fluorescent green and about three feet in diameter, approached Angelucci, who then heard a male voice say in English, “Don't be afraid, Orfeo, we are friends.” The voice said that they had been observing him since his 1946 sighting. It said that the aliens loved all human beings because of an ancient kinship between their planet and earth.
On July 23, 1952, Angelucci experienced a dulling of consciousness followed by the sensation of being in flight. He was in a spherical object when the window opened and he saw the earth from space. He underwent a mystical experience and then returned to earth. Angelucci went public and spread the gospel through lectures and interviews.
As a result he was ridiculed and alienated from family and friends. He was among the speakers at an August 1953 flying-saucer convention in Los Angeles. In 1955 he published his book, The Secret of the Saucers.
Psychologist and philosopher Carl Jung considered that Angelucci's experiences were visions rather than concrete happenings or conscious inventions. Angelucci lapsed into obscurity after the 1950s and is believed to have died in Los Angeles sometime in the 1980s.
