Question: The Lisunov Li-2, originally designated PS-84, was a license-built version of the Douglas DC-3, a fixed-wing propeller-driven airliner, its lasting effect on the airline industry, and which event makes it one of the most significant transport aircraft ever made?

full_context: Document 1: List of Douglas DC-3 family variants: This is a list of variants of the Douglas DC-3 family of airliner and transport aircraft.
Document 2: Boris Lisunov: Boris Pavlovich Lisunov (Russian: Борис Павлович Лисунов , 19 August 1898 – 3 November 1946) was a Soviet aerospace engineer.
Document 3: Petlyakov Pe-8: The Petlyakov Pe-8 was a Soviet heavy bomber designed before World War II, and the only four-engine bomber the USSR built during the war. Produced in limited numbers, it was used to bomb Berlin in August 1941. It was also used for so-called "morale raids" designed to raise the spirit of the Soviet people by exposing Axis vulnerabilities. Its primary mission, however, was to attack German airfields, rail yards and other rear-area facilities at night, although one was used to fly the People's Commissar of Foreign Affairs (Foreign Minister) Vyacheslav Molotov from Moscow to the United States in 1942.
Document 4: Sukhoi: Nine years prior to the creation of the bureau, Pavel Sukhoi, a Soviet Russian aerospace engineer, took over team no. 4 of the CAHI's AGOS aviation, flying boat aviation and aircraft prototype engineering facility, in October 1930. Under Sukhoi's leadership, the team of the future design bureau started to take shape. The team, under the Tupolev OKB, produced experimental fighters such as the I-3, I-14, and the DIP, a record-breaking RD aircraft, the Tupolev ANT-25, flew by famous Soviet aviators, Valery Chkalov and Mikhail Gromov, and the long-range bombers such as the Tupolev TB-1 and the Tupolev TB-3.
Document 5: Douglas C-47 Skytrain: The Douglas C-47 Skytrain or Dakota (RAF designation) is a military transport aircraft developed from the civilian Douglas DC-3 airliner. It was used extensively by the Allies during World War II and remains in front line service with various military operators.
Document 6: Douglas DC-3: The Douglas DC-3 is a fixed-wing propeller-driven airliner. Its cruise speed (207 mph ) and range (1500 mi ) revolutionized air transport in the 1930s and 1940s. Its lasting effect on the airline industry and World War II makes it one of the most significant transport aircraft ever made.
Document 7: Ilyushin Il-96: The Ilyushin Il-96 (Russian: Илью́шин Ил-96 ) is a Russian four-engined long-haul wide-body airliner designed by Ilyushin in the former Soviet Union and manufactured by the Voronezh Aircraft Production Association in Voronezh, Russia. It is powered by four Aviadvigatel PS-90 two-shaft turbofan engines.
Document 8: Ilyushin Il-2: The Ilyushin Il-2 (Cyrillic: Илью́шин Ил-2) Sturmovik was a ground-attack aircraft (Cyrillic: Штурмови́к, "Šturmovík") produced by the Soviet Union in large numbers during the Second World War. With 36,183 units of the Il-2 produced during the war, and in combination with its successor, the Ilyushin Il-10, a total of 42,330 were built, making it the single most produced military aircraft design in aviation history, as well as one of the most produced piloted aircraft in history along with the American postwar civilian Cessna 172 and the Soviet Union's own then-contemporary Polikarpov Po-2 "Kukuruznik" multipurpose biplane.
Document 9: Convair CV-240 family: The Convair CV-240 is an American airliner produced by Convair from 1947 to 1954, initially as a possible replacement of the ubiquitous Douglas DC-3. Featuring a more modern design with cabin pressurization, the 240 series was able to make some inroads as a commercial airliner and also had a long development cycle which resulted in various civil and military variants. Although reduced in numbers through attrition, the "Convairliners" in various forms continue to fly into the 21st century.
Document 10: Lisunov Li-2: The Lisunov Li-2, originally designated PS-84, 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 project was directed by aeronautical engineer Boris Pavlovich Lisunov.
Document 11: Pratt &amp; Whitney R-1830 Twin Wasp: The Pratt & Whitney R-1830 Twin Wasp was an American aircraft engine widely used in the 1930s and 1940s. Produced by Pratt & Whitney, it was a two-row, 14-cylinder, air-cooled radial design. It displaced 1830 cuin and its bore and stroke were both 5.5 in (140 mm). A total of 173,618 R-1830 engines were built, and from their use in two of the most-produced aircraft ever built, the four-engined B-24 heavy bomber and twin-engined DC-3 transport, more Twin Wasps may have been built than any other aviation piston engine in history. A "bored-out" version (to a 5.75 inch/146 mm cylinder bore) with a slightly higher power rating and other slight changes in detail design was produced as the R-2000.
Document 12: Mikulin AM-34: The Mikulin AM-34 (M-34) was a Soviet mass-produced, liquid-cooled, aircraft engine. Before the war, the Russian aero engine industry was mainly engaged in producing engines of foreign design, notably Wright, Bristol, Hispano-Suiza, and Gnome-Rhône. Several engines of so-called original design have been developed, although these were probably largely based on foreign models. The M-34 was thought to have been originally designed in Italy by Fiat for the Russians; its design closely follows Italian in-line aero engine practice. Its initial development was troubled, but it eventually became one of the most successful Soviet aircraft engines of the 1930s. It was utilized on the Beriev MBR-2, Tupolev TB-3, Tupolev TB-4, Tupolev ANT-20, Petlyakov Pe-8, Kalinin K-7, Polikarpov I-17, and Bolkhovitinov DB-A aircraft as well as the G-5 and various prototype motor torpedo boats. A version of the maritime model was adapted for use in several prototype heavy tanks in 1939, although none were placed into production.
Document 13: Douglas SBD Dauntless: The Douglas SBD Dauntless was a World War II American naval scout plane and dive bomber that was manufactured by Douglas Aircraft from 1940 through 1944. The SBD ("Scout Bomber Douglas") was the United States Navy's main carrier-borne scout plane and dive bomber from mid-1940 through mid-1944. The SBD was also flown by the United States Marine Corps, both from land air bases and aircraft carriers. The SBD is best remembered as the bomber that delivered the fatal blows to the Japanese carriers at the Battle of Midway in June 1942. The type earned its nickname "Slow But Deadly" (with the SBD initials) during this period.
Document 14: Consolidated PBY Catalina: The Consolidated PBY Catalina, also known as the Canso in Canadian service, was an American flying boat, and later an amphibious aircraft of the 1930s and 1940s produced by Consolidated Aircraft. It was one of the most widely used seaplanes of World War II. Catalinas served with every branch of the United States Armed Forces and in the air forces and navies of many other nations.
Document 15: Showa/Nakajima L2D: The Shōwa L2D and Nakajima L2D, given the designations: Shōwa Navy Type 0 Transport and Nakajima Navy Type 0 Transport, were license-built versions of the Douglas DC-3. The L2D series, numerically, was the most important Japanese transport in World War II. The L2D was given the Allied code name Tabby.
