The America was a non-rigid airship built by Louis Mutin Godard in France in 1906 for the journalist Walter Wellman's attempt to reach the North Pole by air. Wellman first conceived of using a balloon to fly to the pole during a failed polar attempt by boat and sledge from Svalbard in 1894. He then visited Paris to review the state of balloon technology but left disappointed by the lack of acceptable steering and propulsion capability. A decade later while at the 1905 Portsmouth Peace Conference he learned of recent innovations in French dirigible design and believed a solution might be at hand for his Arctic aerial plan. After receiving the backing of newspaper publisher Victor F. Lawson, the Wellman Chicago Record-Herald Polar Expedition was announced, and Wellman traveled to Paris in search of a suitable design and manufacturer. In the meantime a public company was established to raise the $US 250,000 required for the expedition and airship (to which Lawson contributed $60,000).
As originally constructed, the America was 165 ft (50 m) long and 51 ft 10 in (15.80 m) wide at its greatest diameter and enclosed a volume of 258,000 cubic feet (7,300 m3) of hydrogen. The envelope was of three layers of fabric and three of rubber, and contained no internal framework. The gondola could hold a crew of five, and power was supplied by three internal-combustion engines delivering a total of 80 hp (60 kW) to two propellers, one fore and one aft. It was delivered by ship to Spitsbergen on July 8, 1906, where Wellman and his team attempted to erect it. Their efforts met with failure when the engines fell apart. In September, the America was dismantled and returned by ship to France.
Wellman returned to Spitsbergen with the America in June the following year, 1907. The airship had a new centre-section sewn into it to increase its length to 185 ft (56 m) and volume to 272,000 cubic feet (7,700 m3). The weather was very unfavourable, however, and it was 2 September before the America could even leave the hangar. Wasting no time, Wellman launched later that day with mechanic Melvin Vaniman and navigator Felix Riesenberg in an attempt to reach the pole. Unfortunately, more bad weather forced this to be abandoned after only a few miles and the America was deflated to avoid a crash landing. America once again returned to France for repairs.
She returned to Spitsbergen one more time in July 1909, and at 10 AM on 15 August, launched with Wellman, Vaniman, Russian balloonist Nicolas Popov and Vaniman's brother-in-law Albert Louis Loud on board. The flight began well enough, but two hours and 40 miles (64 km) later, a device Wellman called the "equilibrator" failed. This was a long, leather tube filled with ballast that was intended to help gauge and maintain a fixed altitude over the ice. America gained altitude rapidly, until brought under control at 5,000 ft (1,500 m) and gradually lowered back to the ground by venting hydrogen. The crew was rescued by the Norwegian steamer Farm . [1] Wellman began plans to extend the hangar so that he could return the following year with a larger airship, but on learning [2] of Dr. Frederick Cook's claim to have reached the pole, abandoned the adventure.
Instead, Wellman resolved to make the first aerial crossing of the Atlantic Ocean. He had the America enlarged again, now to 345,000 cu ft (9,800 m3). A spark gap radio set was added to the underhanging life boat and operator Jack Irwin used it during the flight, callsign "W", and with the frame of the airship as the antenna. Given the airship was inflated with hydrogen, this was a very dangerous system. The unit made some of the first air-to-ground transmissions, [3] when the airship's engineer Melvin Vaniman sent one of the first aerial radio transmissions urging the launch boat to "come and get this goddam cat!" – the cat Kiddo who was (at first) not happy about being airborne. [4] [5] [6] [7]
On 15 October 1910, takeoff was made from Atlantic City. [8] [9] Condensing water on the airship's skin added excess weight, and it was difficult to gain height. A passing storm also made forward navigation difficult. The engines failed 38 hours into the flight, apparently due to contamination by beach sand, and America drifted. The crew jettisoned all excess weight, including one of the defunct engines. [9] The ship had gone as far as a point east of New Hampshire and south of Nova Scotia before floating generally south.
After another 33 hours, [9] and having now traveled a total distance of 1,370 miles (2,200 km) from launching, they sighted the Royal Mail steamship Trent west of Bermuda. After attracting the ship's attention by a signaling lamp using Morse code, Irwin made the first aerial distress call by radio. The crew, and mascot cat Kiddo, got into the lifeboat and, after opening the gas valves on the airship, abandoned the America. The airship drifted out of sight and was never seen again. Trent, having barely avoided running down the lifeboat in a high crosswind, was able to rescue the crew and returned them to New York. [10] The first successful aerial crossings of the Atlantic came nine years later.
The North Pole, also known as the Geographic North Pole, Terrestrial North Pole or 90th Parallel North, is the point in the Northern Hemisphere where the Earth's axis of rotation meets its surface. It is called the True North Pole to distinguish from the Magnetic North Pole.
Roald Engelbregt Gravning Amundsen was a Norwegian explorer of polar regions. He was a key figure of the period known as the Heroic Age of Antarctic Exploration.
A Zeppelin is a type of rigid airship named after the German inventor Ferdinand von Zeppelin who pioneered rigid airship development at the beginning of the 20th century. Zeppelin's notions were first formulated in 1874 and developed in detail in 1893. They were patented in Germany in 1895 and in the United States in 1899. After the outstanding success of the Zeppelin design, the word zeppelin came to be commonly used to refer to all forms of rigid airships. Zeppelins were first flown commercially in 1910 by Deutsche Luftschiffahrts-AG (DELAG), the world's first airline in revenue service. By mid-1914, DELAG had carried over 10,000 fare-paying passengers on over 1,500 flights. During World War I, the German military made extensive use of Zeppelins as bombers and as scouts. Numerous bombing raids on Britain resulted in over 500 deaths.
LZ 129 Hindenburg was a German commercial passenger-carrying rigid airship, the lead ship of her class, the longest class of flying machine and the largest airship by envelope volume. She was designed and built by the Zeppelin Company on the shores of Lake Constance in Friedrichshafen, Germany, and was operated by the German Zeppelin Airline Company. She was named after Field Marshal Paul von Hindenburg, who was President of Germany from 1925 until his death in 1934.
An airship is a type of aerostat or lighter-than-air aircraft that can navigate through the air flying under its own power. Aerostats use buoyancy from a lifting gas that is less dense than the surrounding air to achieve the lift needed to stay airborne.
USS O-12 (SS-73) was an O-class submarine of the United States Navy. These later O-boats, O-11 through O-16, were designed by Lake Torpedo Boat to different specifications than the earlier Electric Boat designs. They performed poorly as compared to the Electric Boat units, and are sometimes considered a separate class. The ship was launched in 1917 and entered service with the Navy in 1918 in the Panama Canal Zone.
LZ 127 Graf Zeppelin was a German passenger-carrying hydrogen-filled rigid airship that flew from 1928 to 1937. It offered the first commercial transatlantic passenger flight service. The ship was named after the German airship pioneer Ferdinand von Zeppelin, a count in the German nobility. It was conceived and operated by Hugo Eckener, the chairman of Luftschiffbau Zeppelin.
Umberto Nobile was an Italian aviator, aeronautical engineer and Arctic explorer.
The Norge was a semi-rigid Italian-built airship that carried out the first verified trip of any kind to the North Pole, an 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 the wealthy American adventurer and explorer Lincoln Ellsworth who, along with the Norwegian Aviation Society, financed the trip, which was known as the Amundsen-Ellsworth 1926 Transpolar Flight.
The Italia was a semi-rigid airship belonging to the Italian Air Force. It was designed by Italian engineer and General Umberto Nobile who commanded the dirigible in his second series of flights around the North Pole. The Italia crashed in May 1928, with one confirmed fatality from the crash, one fatality from exposure while awaiting rescue, and six missing crew members who were trapped in the still-airborne envelope. At the end of the rescue operations there were a total of 17 dead and a number of survivors.
The Graf Zeppelin was the last of the German rigid airships built by Zeppelin Luftschiffbau during the period between the World Wars, the second and final ship of the Hindenburg class, and the second zeppelin to carry the name "Graf Zeppelin" and thus often referred to as Graf Zeppelin II. Due to the United States refusal to export helium to Germany, the Graf Zeppelin II was inflated with hydrogen and therefore never carried commercial passengers. It made 30 flights over 11 months in 1938–39, many being propaganda publicity flights; but staff of the Reich Air Ministry were aboard to conduct radio surveillance and measurements. The airship, along with its LZ 127 namesake were both scrapped in April 1940, and their duralumin framework salvaged to build aircraft for the Luftwaffe.
The R.33 class of British rigid airships were built for the Royal Naval Air Service during the First World War, but were not completed until after the end of hostilities, by which time the RNAS had become part of the Royal Air Force. The lead ship, R.33, served successfully for ten years and survived one of the most alarming and heroic incidents in airship history when she was torn from her mooring mast in a gale. She was called a "Pulham Pig" by the locals, as the blimps based there had been, and is immortalised in the village sign for Pulham St Mary. The only other airship in the class, R.34, became the first aircraft to make an east to west transatlantic flight in July 1919 and, with the return flight, made the first two-way crossing. It was decommissioned two years later, after being damaged during a storm. The crew nicknamed her "Tiny".
Walter E. Wellman was an American journalist, explorer, and aeronaut.
Danes Island is an island in Norway's Svalbard archipelago in the Arctic Ocean with an area of 40.6 km2 (15.7 sq mi). It lies just off the northwest coast of Spitsbergen, the largest island in the archipelago, near to Magdalenefjorden. Just to the north lies Amsterdam Island. Most of Svalbard's islands, including Danes Island, are uninhabited; only Spitsbergen, Bjørnøya and Hopen have settlements.
Chester Melvin Vaniman was an American aviator and photographer who specialized in panoramic images. He shot images from gas balloons, ships masts, tall buildings and even a home-made 30-metre (98 ft) pole. He scaled buildings, hung from self-made slings, and scaled dangerous heights to capture his unique images.
A semi-rigid airship is an airship which has a stiff keel or truss supporting the main envelope along its length. The keel may be partially flexible or articulated and may be located inside or outside the main envelope. The outer shape of the airship is maintained by gas pressure, as with the non-rigid "blimp". Semi-rigid dirigibles were built in significant quantity from the late 19th century but in the late 1930s they fell out of favour along with rigid airships. No more were constructed until the semi-rigid design was revived by the Zeppelin NT in 1997.
Virgohamna is a small bay on the northern coast of Danes Island, an island off the northwestern coast of Spitsbergen. Spitsbergen and Danes Island are islands of the Svalbard archipelago. The bay is named after SS Virgo, the vessel of Swedish engineer and explorer Salomon August Andrée's 1896 expedition. Virgohamna is located across a small strait from Smeerenburg, a historical whaling station on Amsterdam Island about 2 km to the north.
The Spitsbergen Airship Museum is a museum located on the island of Spitsbergen in Longyearbyen, the capital of the Arctic Ocean archipelago Svalbard. It has been formally renamed as the North Pole Expedition Museum. It was co-founded by the Italian Stefano Poli and the Norwegian Ingunn Løyning. Plans to open the museum began in 2005. Originally a new building was supposed to be built to house the museum, but following a fallout with one of the share-owners in 2007 this idea was scrapped, and instead the Airship Museum was opened in 2008 in Longyearbyen's former pig farm, which previously had housed the Svalbard Museum as well.
Wellman abandoned his plans when both Robert E. Peary and Frederick A. Cook announced in the fall of 1909 that each claimed to have attained the North Pole by surface travel.
