Umberto Nobile

Umberto Nobile was a prominent Italian aeronautical engineer and Arctic explorer.

He specialized in the development of semi-rigid airships. These aircraft use a partial internal frame to maintain their shape while floating. Nobile believed this design was superior to both rigid and non-rigid airships. His technical expertise helped push the boundaries of long-distance flight during the early 20th century.

Nobile's early career was defined by rapid academic and professional growth. He graduated from the University of Naples in 1908 with a degree in industrial engineering. During World War I, he served as a military engineer in Rome. He worked at the Military Factory for Aeronautical Construction and Experience. In this role, he designed airships for anti-submarine reconnaissance. He also designed the first Italian-made parachute in 1918.

As a director of the Military Factory, Nobile focused on medium-sized airships. He designed the T-34, which the United States Army purchased as the Roma. In February 1922, the hydrogen-inflated Roma crashed in Norfolk, Virginia. It hit high-tension power lines and exploded, causing 34 deaths. This was the worst aviation disaster in the United States at that time. Nobile later worked as a consultant for Goodyear in Akron, Ohio. He also helped design the Caproni Ca.73, Italy's first all-metal aircraft.

Nobile is most famous for his polar expeditions. In 1925, Norwegian explorer Roald Amundsen sought Nobile's help for a North Pole flight. They used the airship Norge, which was built from Nobile's N-1 design.

The Norge departed from Italy in April 1926. On May 11, 1926, the expedition left Svalbard. Fifteen and a half hours later, the airship flew over the North Pole. It eventually landed in Teller, Alaska, due to strong winds. This flight was the first to fly across the polar ice cap from Europe to America.

Despite the success of the Norge, professional tensions arose. Nobile and Amundsen disagreed over who deserved the most credit for the flight. This dispute was worsened by the Italian Fascist government. They used the expedition to promote Italian engineering genius. Nobile was later subjected to professional hostility from figures like Italo Balbo. Balbo obstructed plans for other flights and withheld support for polar exploration.

In 1928, Nobile planned a second expedition using the airship Italia. The Italia was nearly identical to the Norge. It was financed by the city of Milan. On May 23, 1928, the Italia began its flight toward the North Pole. The crew reached the Pole on May 24. However, they soon encountered a severe storm. On May 25, the Italia crashed onto the pack ice near Svalbard.

The crash resulted in a major international crisis. Of the 16 crew members, ten were thrown onto the ice. Six others remained trapped in the buoyant superstructure as it ascended. One man, Pomella, died from the impact. Nobile suffered several injuries, including a broken arm, leg, and rib. The survivors faced extreme conditions on the drifting sea ice. Some crew members, including engineer Ettore Arduino and five others, were carried away by the airborne airship envelope.

A massive international rescue effort followed the crash. Nations including the Soviet Union, Norway, Sweden, Finland, and Italy participated. Even Roald Amundsen joined the effort by flying a seaplane. Tragically, Amundsen's plane disappeared, and he was never found. A Swedish pilot, Einar Lundborg, eventually airlifted Nobile from the ice. However, Lundborg refused to take other seriously injured survivors. Nobile faced further difficulties when he returned to Italy. He was met with censorship and false reports regarding his conduct. He lived until 1978, leaving behind a complex legacy in aviation history.
