In short: In the early era of submarine warfare, accidents often meant certain death. This video explores how naval officer Charles Momsen developed specialized equipment to rescue sailors from a ghastly fate during a critical test in May 1939.

During the early age of submarines, limited technology meant that trapped submariners had very few chances of survival if an accident occurred. This changed when naval officer Charles Momsen designed new equipment specifically to save those caught in such disasters.
