Felice Trojani (Rome, April 18, 1897 - Rho, November 3, 1971) was an Italian engineer, designer of airships and airplanes.
The AUT.18 was a prototype fighter aircraft developed in Italy by Aeronautica Umbra shortly before the outbreak of World War II.
 It was designed in 1934 by Ing Felice Trojani, who at that time was collaborating with Umberto Nobile on the Arctic flights of the airships "Norge" and "Italia".
 The aircraft's designation came from initials of the manufacturer, the surname of the designer, and the aircraft's wing area (18 m²), the sole prototype receiving the serial no.
 "M.M.363".
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.
Giuseppe Biagi (Medicina February 2, 1897 - Rome, November 1, 1965) was a soldier, explorer and Italian radio operator, who took part in the expedition of Umberto Nobile to the North Pole in the airship Italy, in May 1928.
Airship "Italia" was a semi-rigid airship used by Italian engineer Umberto Nobile in his second series of flights around the North Pole.
 It crashed in 1928, with one confirmed fatality from the crash, one fatality from exposure while awaiting rescue, and the disappearance (and presumed death) of six crew members who were trapped in the still-airborne envelope.
Nobile Glacier ( ) is a glacier flowing into the southeast part of Recess Cove, Charlotte Bay, on the west coast of Graham Land.
 Charted by the Belgian Antarctic Expedition under Gerlache, 1897-99.
 Named by the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1960 for Umberto Nobile, Italian designer of the rigid airships Norge and respectively.
 Glacier is located in the closest part of Antarctica to South America.
The Société Latham was a French aeronautical construction company which built seaplanes for the French Navy.
 It is best known for the prototype of the Latham 47 which disappeared in 1928 with Roald Amundsen onboard during a rescue mission to the North Pole in search of Umberto Nobile (a memorial to which was set up in Caudebec-en-Caux in 1931, by the sculptor Robert Delandre and the architect Léon Rey).
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.
Leif Dietrichson (1 September 189018 June 1928) was a Norwegian military officer and aviation pioneer.
 He is most famous for joining Roald Amundsen and Lincoln Ellsworth in the 1925 North Pole Expedition.
 In 1928, Dietrichson disappeared with Amundsen and four others as they were looking for the expedition of Umberto Nobile.
The "Norge" Storage Site is a historic building in the small native city of Teller, Alaska.
 It is a two-story wood frame building with a false front, and a small single-story addition to the east.
 The building's notability lies with its association with the groundbreaking voyage of the dirigble "Norge", which overflew the North Pole on May 11, 1926.
 Commanded by the explorer Roald Amundsen and its Italian maker, Umberto Nobile, the airship flew from Spitsbergen, Norway on May 10, and made for Nome after crossing the pole.
 Frustrated by fog and bad weather, the ship was landed instead at Teller, about 72 mi from Nome, landing on Front Avenue near this building.
 The airship was dismantled and stored here until a freighter could be sent to recover it.
