Futility Closet

In 1943 German submarines were devastating the merchant convoys carrying supplies to Britain. Unable to protect them with aircraft or conventional ships, the resource-strapped Royal Navy considered an outlandish solution: a 2-million-ton aircraft carrier made of ice. In this episode of the Futility Closet podcast we follow the strange history of the project, which Winston Churchill initially praised as dazzling but which ended in ignominy at the bottom of a Canadian lake. We'll also discover a love pledge hidden for 200 years in the heart of a Yorkshire tree and puzzle over the deaths of two men in a remote cabin. Our segment on Project Habbakuk is based chiefly on L.D. Cross' 2012 book Code Name Habbakuk. In the photo above, research workers cut ice and form it into beams on Lake Louise near the Chateau Lake Louise resort hotel in 1943. Our post on the Yorkshire inscription appeared on Dec. 18, 2009.
