The tot: A mystery unsolved 6/6al length of 6 parts 55 min

 

On 27 March 1968, while on a routine training flight from Chkalovsky Air Base, he and flight instructor Vladimir Seryogin died in a MiG-15UTI crash near the town of Kirzhach. The bodies of Gagarin: Celebration in Moscow and Seryogin were cremated and the ashes were buried in the walls of the Kremlin on Red Square.

Gagarin had become deputy training director of the Star City cosmonaut training base. At the same time, he began to re-qualify as a fighter pilot.

The cause of the crash that killed Gagarin is not entirely certain, and has been subject to speculation and conspiracy theories over the ensuing decades.

Russian documents declassified in March 2003 showed that the KGB had conducted their own investigation of the accident, in addition to one government and two military investigations. The KGB's report dismissed various conspiracy theories, instead indicating that the actions of air base personnel contributed to the crash. The report states that an air traffic controller provided Gagarin with outdated weather information, and that by the time of his flight, conditions had deteriorated significantly. Ground crew also left external fuel tanks attached to the aircraft. Gagarin's planned flight activities needed clear weather and no outboard tanks. The investigation concluded that Gagarin's aircraft entered a spin, either due to a bird strike or because of a sudden move to avoid another aircraft. Because of the out-of-date weather report, the crew believed their altitude to be higher than it actually was, and could not properly react to bring the MiG-15 out of its spin.

In his 2004 book Two Sides of the Moon, Alexey Leonov recounts that he was flying a helicopter in the same area that day when he heard "two loud booms in the distance." Corroborating other theories, his conclusion is that a Sukhoi jet (which he identifies as a Su-15 'Flagon') was flying below its minimum allowed altitude, and "without realizing it because of the terrible weather conditions, he passed within 10 or 20 meters of Yuri and Seregin's plane while breaking the sound barrier." The resulting turbulence would have sent the MiG into an uncontrolled spin. Leonov believes the first boom he heard was that of the jet breaking the sound barrier, and the second was Gagarin's plane crashing.

Another theory, advanced by the original crash investigator in 2005, hypothesizes that a cabin air vent was accidentally left open by the crew or the previous pilot, leading to oxygen deprivation and leaving the crew incapable of controlling the aircraft. A similar theory, published in Air & Space magazine, is that the crew detected the open vent and followed procedure by executing a rapid dive to a lower altitude. This dive caused them to lose consciousness and crash.
 

On 12 April 2007, the Kremlin vetoed a new investigation into the death of Gagarin. Government officials said that they saw no reason to begin a new investigation.

In April 2011, documents from a 1968 commission setup by the Central Committee of the Communist Party to investigate the accident were declassified. Those documents revealed that the commission's original conclsuion was that either Gagarin or Seryogin had manoeuvred sharply, likely to avoid a weather balloon, leading the jet into a "supercritical flight regime and to its stalling in complex meteorological conditions". The report also suggested the jet may have been manoeuvring sharply to avoid "entry into the upper limit of the first layer of cloud cover"
