|ANT-20 "Maksim Gorky"|
|National origin||Soviet Union|
|First flight||19 May 1934|
|Primary user||Soviet Union|
|Developed from||Tupolev TB-4|
The ANT-20 was designed by Andrei Tupolev, using the all-metal airframe technologies devised by German engineer Hugo Junkers during the World War I years, and constructed between 4 July 1933 and 3 April 1934. It was one of two aircraft of its kind built by the Soviets. The aircraft was named after Maxim Gorky and dedicated to the 40th anniversary of his literary and public activities. The ANT-20 was the largest known aircraft to have used the Junkers design philosophy of corrugated sheet metal for many of the airframe's key components, especially the corrugated sheet metal skinning of the airframe.
It was intended for Stalinist propaganda purposes and was equipped with a powerful radio set called "Voice from the sky" ("Голос с неба", Golos s neba), printing machinery, library, radiostations, photographic laboratory and a film projector with sound for showing films in flight. In a first in aviation history the aircraft was equipped with a ladder which would fold on itself to become part of the floor.
Another first for the plane is that it used both direct current and alternating current. The aircraft could be dismantled and transported by rail if needed. The aircraft set several carrying capacity world records and is also the subject of a 1934 painting by Vasily Kuptsov, which is now in the collection of the Russian Museum at St. Petersburg.
1935 Maksim Gorky crash
On 18 May 1935, the Maxim Gorky (pilots – I. V. Mikheyev and I. S. Zhurov) and three more planes (Tupolev ANT-14, R-5 and I-5) took off for a demonstration flight over Moscow. The main purpose of the other three planes flying so close was to make evident the difference in size. As a result of a poorly executed loop manoeuvre (a third such stunt on this flight) around the plane performed by an accompanying I-5 fighter (pilot – Nikolai Blagin), both planes collided and the Maxim Gorky crashed into a low-rise residential neighbourhood west of present-day Sokol metro station.
Forty-five people were killed in the crash, including both pilots and their 33 passengers, family members of some of those who had built the aircraft. (While authorities announced that the fatal manoeuvre was impromptu and reckless, it has been recently suggested[by whom?] that it might have been a planned part of the show.) Also killed was the fighter pilot, Blagin, who was made a scapegoat in the crash and subsequently had his name used eponymously (Blaginism) to mean, roughly, a "cocky disregard of authority." However, Blagin was given a state funeral at Novodevichy Cemetery together with ANT-20 victims.
A replacement aircraft, designated ANT-20bis had begun production the following year and first flew in 1938. It was largely identical in design but with six more-powerful engines. This plane, designated PS-124 and registered CCCP-L760, served with Aeroflot on transport routes in Russia and Uzbekistan. On 14 December 1942, it also crashed after the pilot allowed a passenger to take his seat momentarily and the passenger apparently disengaged the automatic pilot, sending the airplane into a nosedive from an altitude of 500 m (1,500 ft) and killing all 36 on board.
