Join the boys this week as they finish the story of the raising of the submarine Squalus. The story left off with the Squalus stuck in 240 feet of cold Atlantic water and divers were attaching the new McCann Rescue Chamber to the sub to begin rescue operations. At 240 feet the divers were on air and in the late 1930's helium use was in it's infancy and still being "felt out" so it was not being employed but several events during this rescue would change that position. Join us in part "trois" of The Raising of The Sqalus!
