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. ==Design and specifications== ''Italia'' was an N-class semi-rigid airship, designation N-4. In design it was almost identical to the N-1 ''Norge'' but slightly larger in gas capacity. Little is known of airship N-2. Airship N-3 was sold to Japan and became "Naval Airship No. 6". Nobile and some of his staff traveled to Japan in 1926 or 1927 to deliver this airship.〔Wilbur Cross, Disaster at the Pole, 2002 ISBN 1-58574-496-4〕 According to Italian sources, airship N-5 (which was larger and had three times the lifting capacity of N-1) was Nobile's preferred design for the Arctic expedition, but when funding was refused by the Italian government he built N-4 with the assistance of private backers and the City of Milan. In May 1928 the Italia set off for the Arctic Circle, stopping at a German airship hangar at Stolp, Pomerania, and the airship mast at Vadsø in Norway. *First flight: 1924 〔Ventry and Kolesnik, Jane's Pocket Book of Airships, Collier, 1977〕 *Length: 105.4 metres/347.8 feet *Diameter: 19.4 metres/63.9 feet *Gas capacity: 18,500 cubic metres/654,000 cubic feet *Performance: 112.3 km/h /70.2 mph *Payload: 9405 kg/20,900 LB *Power plant: 3 Maybach 560 kW/750 hp total 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Airship Italia」の詳細全文を読む スポンサード リンク
