"I am very glad to be here today in Groton, Connecticut."
"And I think we have started something that will, in the long run--maybe 50 years from now--make history."
"We are assembled here to lay the keel of a Navy submarine, the U.S.S. Nautilus."
"The Nautilus will be able to move under the water at a speed of more than 20 knots."
