The Diving Bell
Momsen returned to his diving bell idea in 1930. He built a prototype, constructed from a water-tight aircraft hangar pirated from S-1 and tested it off Key West, Florida. Momsen stated the bell was unstable, tipped, and leaked, and had several changes in mind for the diving bell, but was sent to the Bureau of Construction and Repair to teach submariners how to use the Momsen lung before he could make the changes. Lieutenant Commander Al McCann was put in charge of the revisions on the Momsen / McCann diving bell. When the redesigned diving bell was completed in late 1930, it was introduced as the McCann Submarine Rescue Chamber. Momsen stated the redesign was a significant improvement over the prototype. The design incorporated a floor bulkhead, a pneumatic winch, and a pressure seal allowing direct transfer of survivors to the diving bell in a dry environment.

Famous quotes containing the words diving and/or bell:
“all the fine
Points of diving feet together toes pointed hands shaped right
To insert her into water like a needle”
—James Dickey (b. 1923)
“One of the most difficult aspects of being a parent during the middle years is feeling powerless to protect our children from hurt. However “growthful” it may be for them to experience failure, disappointment and rejection, it is nearly impossible to maintain an intellectual perspective when our sobbing child or rageful child comes in to us for help. . . . We can’t turn the hurt around by kissing the sore spot to make it better. We are no longer the all-powerful parent.”
—Ruth Davidson Bell (20th century)
