Allan Rockwell McCann was in charge of the development of a submarine rescue chamber, which bears his name, "The McCann Submarine Rescue Chamber". Additionally he was assigned as Liaison Officer / Engineer when the submarine was converted for use in the under ice attempt to circumnavigate the Arctic Ice cap and voyage to the North Pole. Modifications to the submarine were extensive, and contained innovations of a telescoping conning tower, an ice drill, an incorporated diving bell and an Air Lock, designed by Simon Lake. The submarine was designated "Nautilus" and leased for one dollar to Lake and Danenhower, Inc., of Bridgeport, Connecticut,
Pole to Pole flying there on a small aeroplane fitted with skis. The North Pole scene was filmed in May 1992, after the rest of the series had been shot, as weather conditions were more suitable then as the ice was too fragile the previous year. From there, he heads to Greenland, then the Norwegian island of Spitsbergen, where the towns of Ny Ålesund and Longyearbyen are located. From there he sails across the Barents Sea on a supply ship to the Norwegian port city of Tromsø, where he visits a statue of Roald Amundsen, the first man to reach the South Pole.
