#OTD in 1959, Submarine Voyage opened at #Disneyland. The attraction was inspired in part by the 1958 submerged transit of the North Pole by USS Nautilus. The ride's eight "subs" (which did not actually submerge) were built with advice from General Dynamics' Electric Boat Division and named after U.S. Navy nuclear submarines. Walt boasted that he had the eighth largest sub fleet in the world. The attraction closed in 1998 and reopened in 2007 with a theme based on "Finding Nemo". #SubSunday | U.
