He was a recipient of the Medal of Honor, the highest honor for valor given by the United States, and was a pioneering American aviator, polar explorer, and organizer of polar logistics. Aircraft flights in which he served as a navigator and expedition leader crossed the Atlantic Ocean, a segment of the Arctic Ocean, and a segment of the Antarctic Plateau. Byrd claimed that his expeditions had been the first to reach both the North Pole and the South Pole by air. However, his claim to have reached the North Pole is disputed.

Document 3: Umberto Nobile: Umberto Nobile (] ; 21 January 1885 – 30 July 1978) was an Italian aviator, aeronautical engineer and Arctic explorer. Nobile was a developer and promoter of semi-rigid airships during the period between the two World Wars. He is primarily remembered for designing and piloting the airship "Norge", which may have been the first aircraft to reach the North Pole, and which was indisputably the first to fly across the polar ice cap from Europe to America. Nobile also designed and flew the "Italia," a second polar airship; this second expedition ended in a deadly crash and provoked an international rescue effort.
Document 4: Norge (airship): The Norge was a semi-rigid Italian-built airship that carried out the first verified trip of any kind to the North Pole and likely the first verified overflight on 12 May 1926. It was also the first aircraft to fly over the polar ice cap between Europe and America. The expedition was the brainchild of polar explorer and expedition leader Roald Amundsen, the airship's designer and pilot Umberto Nobile and American explorer Lincoln Ellsworth, who along with the Aero Club of Norway, financed the trip which was known as the Amundsen-Ellsworth 1926 Transpolar Flight.

These, like the German Groß-Basenach semi-rigid airships, were the first to have the gondola attached to the envelope, to reduce air resistance.
Document 11: Roald Amundsen: Roald Engelbregt Gravning Amundsen (] ; 16 July 1872 – c. 18 June 1928) was a Norwegian explorer of polar regions. As the leader of the Antarctic expedition of 1910–12, which was the first to reach the South Pole, on 14 December 1911, he was a key expedition leader during the Heroic Age of Antarctic Exploration. In 1926, he was the first expedition leader for the air expedition to the North Pole, making him the first person, without dispute, to reach both poles.

After a badly distributed second work Biagetti abandoned films, devoting himself to the production and direction of commercials. He came back to cinema in 1968, directing two commercially successful films which had some political and social commitment, then since 1972 he focused on more low-profile genre films, in which he was sometimes credited as Pier Giorgio Ferretti.

He won international fame after reaching a record northern latitude of 86°14′ during his North Pole expedition of 1893–96. Although he retired from exploration after his return to Norway, his techniques of polar travel and his innovations in equipment and clothing influenced a generation of subsequent Arctic and Antarctic expeditions.
Document 14: Gianni Bisiach: Born in Gorizia, after getting his degree in Medicine Bisiach enrolled at the Centro Sperimentale di Cinematografia.
