Charles Hickson and Calvin Parker

This famous case from October 1973 involved two co-workers who were fishing on the Pascagoula River in Mississippi. They claim they were levitated onto a spaceship. There they were subjected to some form of medical examination by humanoid creatures with claws like a lobster on the end of their arms. Later, they reported their experience to the local police, who thought the men seemed sincere and genuinely frightened.
