I watched an episode of Vanishings! today and it was the episode on the disappearance of Lionel Crabb while investigating the hull of a Soviet ship. My interest in Crabb was first piqued at the same time as the Loch Ness Monster, Spring Heeled Jack and Jack the Ripperas all the stories were in the same unsolved mysteries book I picked up when in the 5th grade.
The files on the Crabb disappearance aren't due to be released until 2057! Don't think I'll make it to see the day.
