On June 8, 1937, the legendary nonstop flight of Soviet aviators along the route Moscow – North Pole – Vancouver commenced. The crew, consisting of commander V.P. Chkalov, co-pilot G.F. Baidukov, and navigator A.V. Belyakov, had an ambitious goal: to "connect" the continents for the first time in history via the shortest route – over the Arctic Ocean. Especially for this and other long-distance flights, Soviet aircraft designer A.N. Tupolev created the single-engine ANT-25 with an extended wing within just one year. This design allowed for more fuel to be carried and increased the gliding capabilities of the aircraft. The flight, which lasted a total of 63 hours and 16 minutes, took place under extreme conditions. Due to Arctic cold, ice had to be manually scraped off the cockpit windows with a Finnish knife, and the engine was cooled with tea and coffee from thermoses (intended water supplies had frozen). Because of cloud fronts, the pilots had to either fly the plane blind or change course, which resulted in an overuse of about 300 liters of fuel. The flight of V.P. Chkalov’s crew became one of the greatest events in the history of world aviation. It demonstrated the advanced nature of Soviet achievements in aircraft construction and proved to the entire world the high professionalism and bravery of Soviet aviators. The feat of the three pilots was widely covered in the press – both Soviet and American. U.S. President F.D. Roosevelt personally received the crew in the Oval Office of the White House. Instead of the planned 15-minute conversation, he spoke with the Soviet crew for 1 hour and 40 minutes. Interesting: during the preparations for the flight, a network of radio stations was put into operation along the entire Northern Sea Route. Furthermore, the flight was specifically planned during the operation of the drifting polar station "North Pole - 1" under the leadership of Ivan Papanin, which started on June 6, 1937. From the station, the pilots even managed to receive a weather report, but during their passage through this area, the antenna of the onboard radio station of the ANT-25 failed. Thus, over the Arctic Ocean, the crew flew without communication.
