Skate was unable to surface precisely at the Pole on her August voyage 1958, due to dangerous ice conditions as noted in the captain's 1960 book, Surface at the Pole: The Extraordinary Voyages of the USS Skate, where Commander James F. Calvert, said "Seldom had the ice seemed so heavy and so thick as it did in the immediate vicinity of the pole. For days we had searched in vain for a suitable opening to surface in." The closest was to make radio contact at the surface from a polynya around 30 nm away, but not to surface fully owing to the risk of damage from ice. Skate did manage to surface and make contact with Drifting Ice Station Alpha at 85ºN, 300 nm away.
While the Skate was unable to surface on its first voyage to the pole, on 17 March 1959, she became the first submarine to surface at the North Pole with Calvert describing the historic moment in his book, saying, "Slowly we blew the tanks and the Skate moved reluctantly upward. It was apparent we were under heavier ice here than any we had experienced before." While at the pole, Calvert and the crew planted an American Flag in a cairn they built out of ice blocks and put a waterproof container in the cairn with a note commemorating the event. The crew also held a ceremony for the late Arctic explorer Sir Hubert Wilkins and committed his ashes at the pole. In 1931, Sir Hubert had conducted an Arctic expedition in the disarmed research submarine Nautilus. After reaching the Pole, the Skate continued its mission to pioneer arctic operations during periods of extreme cold and maximum ice thickness. When the submarine returned to port, she was awarded a bronze star in lieu of a second Navy Unit Commendation for demonstrating "... for the first time the ability of submarines to operate in and under the Arctic ice in the dead of winter...."
The first landing at the North Pole and the first men, which has been confirmed, to stand on North Pole was the three planes of the Soviet Union Sever-2 expedition of 24 scientists and flight crew led by Aleksandr Kuznetsov.
The expedition used the Lisunov Li-2 aircraft, originally designated PS-84, which was a license-built version of the Douglas DC-3. It was produced by Factory #84 in Moscow-Khimki and, after evacuation in 1941, at TAPO in Tashkent.
The pilots were: Ivan Cherevichnyy, Vitaly Maslennikov and Ilya Kotov. Cherevichnyy's plane was the first one to land at 4:44pm on April 23rd, 1948.
Russia's interest in the North Pole was driven by economic prospects and the opportunity for technological advancement. A northern sea route would allow passage of commercial and war ships, and would establish refueling and supply stations for ships and aircraft in remote areas. For navigation, meteorological stations were built providing better weather forecasting for northern Europe and Asia.
Weather, temperature, and reliance on aviation gauges were key elements in the first transpolar flight. Once over the Pole, the Chkalov crew encountered stormy, cold weather, throwing the ANT-25 off course and burning more fuel as they tried to fly above the storm. Baidukov, the co-pilot, and Chkalov slept in shifts as they manned the controls, while Belyakov, the navigator, took short naps to stay alert for navigation needs. Ice formed unevenly, endangering structural integrity and weighing down the aircraft. The higher they flew, the greater the crew's demand for oxygen. Baidukov prevailed by "flying blind" with instruments only. They were an excellent team. With Chkalov's steady guidance, Belyakov's expert navigation, and Baidukov's skills, they flew 5,288 miles through white skies and over unfamiliar territories. Through diplomatic arrangement, Russian and American meteorologists and radio operators communicated with the crew throughout the flight, though the fliers reported reception difficulties several times.
On the morning of June 20 in Vancouver, Washington, people were dressing for church, milkmen were beginning their deliveries, and the commanding general of the US Army's Department of the Columbia was sipping coffee in a beautiful house on Officers' Row. No one realized the magnitude of the aerial achievement that was about to unfold at Pearson Field.
In a huge, glider-like airplane above Eugene, Oregon, Valery Chkalov and his crew realized they were running out of fuel and would not make it to Oakland, California, as planned. Chkalov told his copilot, Georgi Baidukov, to turn the ANT-25 back towards Portland. Droplets of rain glistened on Baidukov's face as he leaned out the cockpit window. "I need the detailed map," he shouted to navigator Alexander Belyakov. "That's it," Chkalov whispered a short time later, as he gazed at photos of American airports and recognized the bridges and factories below.
AMERICA! Sixty-three hours and sixteen minutes from the time they left Moscow, the world's first transpolar flight landed safely at Pearson Field. This dangerous, fantastic flight matched the glitz and glamour of Earhart and Lindbergh, but few in America would realize its lasting impact. Three men endured incredible cold, hazards, exhaustion, and a lack of oxygen to fly over the North Pole, setting world records in the process.
Graf Zeppelin’s 1931 Arctic Flight was both a scientific expedition and a theatrical display of the airship’s ability.
In July, 1931, the ship carried a team of scientists from Germany, the United States, the Soviet Union, and Sweden on an exploration of the Arctic, making meteorological observations, measuring variations in the earth’s magnetic field in the latitudes near the North Pole, and making a photographic survey of unmapped regions using a panoramic camera that automatically took several pictures per minute. The size, payload, and stability of the zeppelin allowed heavy scientific instruments to be carried and used with an accuracy that would not have been possible with the airplanes of the day.
The five-stage flight covered 7,187 nautical miles in 136:26 flying hours between July 24th and July 31st, 1931, and literally changed the map of the Arctic region with the information obtained during the flight.
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 of six crew members who were trapped in the still airborne envelope.
Nobile planned five flights for the expedition, each starting from and returning to Ny-Ålesund (Kings Bay) and exploring different areas of the Arctic.
After the necessary engine and structural repairs were completed, the first flight departed from Kings Bay on 11th May 1928. Italia was forced to turn back after only eight hours flight because of thick ice forming on the envelope, as well as fraying of the control cables due to the extreme conditions.
The second flight left at 13:20 on 15th May and lasted 60 hours. In contrast, this time the weather conditions were excellent and visibility perfect. Valuable meteorological, magnetic and geographic data were gathered in a 2,500 mile (4,000 km) flight to the hitherto uncharted Nicholas II Land and back. Malmgren gathered weather and ice observations, while Pontremoli and Běhounek made measurements of magnetic phenomena and radioactivity. The ship returned safely to base on the morning of 18 May.
The third flight started on 23 May 1928, and following a route along the Greenland coast, with the assistance of strong tailwinds, reached the North Pole 19 hours later at 00:24 on 24 May 1928. Nobile had prepared a winch, an inflatable raft, and survival packs (providentially as it turned out) with the intention of lowering some of the scientists onto the ice, but the wind made this impossible. Instead they circled the pole making observations and at 01:20 dropped the Italian and Milanese colours, as well as a wooden cross presented by the Pope and a religious medal from the citizens of Forlì onto the ice during a short ceremony. At 02:20 on 24 May, the Italia started back to base.
The same tail wind that had helped Italia to the Pole now impeded their progress. Nobile calculated the return journey would take 40 hours, and had discussed their options with Dr Malmgren in the hours before their arrival at the Pole. Nobile considered a trans-polar route to Mackenzie Bay in Canada. According to Nobile, Malmgren advised a return to Kings Bay, predicting lessening winds on their return trip. On the other hand, Malmgren predicted a head wind all the way if the Canadian route was attempted. No doubt the prospect of a forced landing in the Canadian wilderness was unpalatable to both men, as it would mean the end of the expedition.
Heading directly south on a heading for Kings Bay, after 24 hours of increasing head winds and thick mist the Italia was only halfway back to base. The airship struggled to gain ground and break through to the zone of calmer winds which expedition meteorologist Finn Malmgren predicted was just ahead. Ice formed on the propellers and shot off into the envelope, necessitating running repairs. Engine speed was increased but with little effect, except for a doubling of fuel consumption. Dr Běhounek, in charge of the compass, started reporting variations in course of up to 30 degrees, and the elevator man Cecioni had similar problems maintaining control. By 07:30 on 25 May, Nobile, who had been awake for over 48 hours, knew that the situation was critical and Giuseppe Biagi, the wireless operator, sent out the message: "If I don't answer, I have good reason". By dead reckoning, Nobile estimated his position as 250 miles (400 km) northeast from Moffen Island. This estimate was 350 miles (560 km) off.
At 9:25am on 25 May the first critical incident occurred, when the elevator control jammed in the downward position while the ship was travelling at less than 1000 feet (300 metres) altitude. All engines were stopped and the airship began to rise again after it had dropped to within 300 feet (90 metres) of the jagged ice pack. The airship was allowed to continue rising to 3000 feet (900 metres) and above the cloud layer into bright sunlight for 30 minutes. After two engines were restarted the ship descended to 1000 feet (300 metres) with no apparent ill effect, with the headwind appearing to decrease slightly allowing an airspeed of 30 mph. Malmgren took the helm with Zappi supervising him. Cecioni continued to operate the elevators.
At 10:25 the ship was noticed to be tail-heavy and falling at a rate of 2 feet per second (0.6 m/s). Nobile ordered full elevators and emergency power, but although the nose rose to an upward angle of 21 degrees, the descent continued. Nobile ordered foreman rigger Renato Alessandrini to the tail of the envelope to check the automatic gas valves. A short time later, seeing a crash was unavoidable, Nobile ordered full stop and the cutting of electrical power to prevent a fire on impact. The port engine engineer failed to notice the order and the ship began to bank. At the same time Nobile ordered Cecioni to dump the ballast chain, but was unable to carry out the order in time owing to the steep angle of the floor and the secure way the chain was lashed.
Seconds afterwards the airship's control cabin hit the jagged ice and smashed open. Suddenly relieved of the weight of the gondola, the envelope of the ship, with a gaping tear in the keel and part of one cabin wall still attached, began to rise again.
Nine survivors including Nobile's fox terrier and one fatality were left on the ice, and six more crew were trapped in the still drifting airship envelope. The envelope and the crew members aboard it have never been found. The position of the crash was close to 81°14′N 28°14′E, about 120 km (75 mi) northeast of Nordaustlandet, Svalbard. The drifting sea ice later took the survivors towards Foyn and Broch islands.
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 12th 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.
In 1925, Amundsen telegrammed Nobile asking to meet him at Oslo, where he proposed an airship trip across the Arctic. With a contract in place Nobile modified the N-1 for cold conditions. As the expedition was being financed by the Aero Club of Norway the modified N-1 was given the name Norge.
On 12th May at 01.25 (GMT) they reached the North Pole, at which point the Norwegian, American and Italian flags were dropped from the airship onto the ice. Relations between Amundsen and Nobile, which had been strained in the freezing, cramped and noisy conditions became even worse when Amundsen saw that the Italian flag dropped was larger than either of the others. Amundsen later recalled with scorn that under Nobile, the airship had become "a circus wagon in the sky".
On 14th May the Norge reached the Inupiat village of Teller, Alaska where in view of worsening weather, the decision was made to land rather than continue to Nome. The airship was reportedly damaged during the landing and was dismantled and shipped back to Italy.
The three previous claims to have arrived at the North Pole—by Frederick Cook in 1908, Robert Peary in 1909, and Richard E. Byrd in 1926 (just a few days before the Norge)—are all disputed as being either of dubious accuracy or outright fraud. Some of those disputing these earlier claims therefore consider the crew of the Norge to be the first verified explorers to have reached the North Pole.
On May 9th, 1926, Byrd and Navy Chief Aviation Pilot, Floyd Bennett, attempted a flight over the North Pole in a Fokker F.VIIa/3m Tri-motor monoplane named Josephine Ford, after the daughter of Ford Motor Company president Edsel Ford, who helped finance the expedition. The flight went from Spitsbergen (Svalbard) and back to its take-off airfield, lasting 15 and 57 (including 13 minutes of a claimed circling of the pole). Byrd and Bennett claimed to have reached the pole, a distance of 1,335 nautical miles return.
When he returned to the United States from the Arctic, Byrd became a national hero. Congress passed a special act on December 21st, 1926, promoting him to the rank of commander and awarding both him and Floyd Bennett the Medal of Honor. Bennett was promoted to the warrant officer rank of Machinist. Byrd and Bennett were presented with Tiffany Cross versions of the Medal of Honor on March 5th, 1927, at the White House by President Calvin Coolidge.
His claim, widely accepted at first, has been challenged since.
The 1996 release of Byrd's diary of the May 9th, 1926, flight revealed erased (but still legible) sextant sights that sharply differ with Byrd's later June 22nd typewritten official report to the National Geographic Society. Byrd took a sextant reading of the Sun at 7:07:10 GMT. His erased diary record shows the apparent (observed) solar altitude to have been 19°25'30", while his later official typescript reports the same 7:07:10 apparent solar altitude to have been 18°18'18". On the basis of this and other data in the diary, Dennis Rawlins concluded that Byrd steered accurately, and flew about eighty percent of the distance to the Pole before turning back because of an engine oil leak, but later falsified his official report to support his claim of reaching the pole.
