Andy Williams is a veteran of the Royal Navy and served on HMS Glasgow during the Falklands War.
Glasgow saw action early in the war when her Lynx helicopter severely damaged the Argentine naval vessel, Alferez Sobral.
Glasgow then detected an Exocet missile fired at the Task Force and warned the fleet.
HMS Sheffield failed to receive the warning and was hit, later sinking.
Andy found himself just inches away from an Argentine missile that struck the side of his ship.
