On the evening of 11 October 1973, 19-year-old Calvin Parker was fishing with a friend on the Pascagoula River in Mississippi. It started just like one of many peaceful evenings, but things took a turn for the worse when three creatures with 'leathery grey skin and crab-like claws' grabbed hold of the two men and pulled them aboard their spacecraft. After a thorough and intrusive examination, Calvin claims he was returned to land.
The story quickly gained local notoriety but Calvin spent decades shying away from the press - until now.
Amid the release of his book Pascagoula - The Closest Encounter, Calvin joins us live from New Orleans, Louisiana, to tell us his version of events.
