Building Hitler's SupergunJuly 1, 2016

In 1944 the British and the Americans went head to head in a race to destroy a new Nazi secret weapon - an enormous canon with the range to bombard London from France. Large scale practical experiments solve outstanding mysteries, such as whether shells from the Supergun could really have reached London, and how a man groomed to be a future president of the USA (Joe Kennedy) lost his life unnecessarily on a mission to destroy the weapon.
