that Gagarin never said these words and that the quote originated from Khrushchev's speech at the plenum of the Central Committee of the CPSU about the state's anti-religion campaign, saying "Gagarin flew into space, but didn't see any god there". Petrov also said Gagarin had been baptised into the Russian Orthodox Church as a child, and a 2011 Foma magazine article quoted the rector of the Orthodox Church in Star City saying, "Gagarin baptized his elder daughter Yelena shortly before his space flight; and his family used to celebrate Christmas and Easter and keep icons in the house". Death On 27 March 1968, while on a routine training flight from Chkalovsky Air Base, Gagarin and flight instructor Vladimir Seryogin died when their MiG-15UTI crashed near the town of Kirzhach. The bodies of Gagarin and Seryogin were cremated and their ashes interred in the walls of the Kremlin. Wrapped in secrecy, the cause of the crash that killed Gagarin is uncertain and became the subject of several theories, including several conspiracy theories. At least three investigations into the crash were conducted separately by the Air Force, official government commissions, and the KGB. According to a biography of Gagarin by Jamie Doran and Piers Bizony, Starman: The Truth Behind the Legend of Yuri Gagarin, the KGB worked "not just alongside the Air Force and the official commission members but against them." The KGB's report, declassified in March 2003, claimed that the actions of airbase 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 The report states that an air-traffic controller provided Gagarin with outdated weather information and that by the time of his flight, conditions had deteriorated significantly.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 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 Because of the out-of-date weather report, the crew believed their altitude was higher than it was and could not react properly to bring the MiG-15 out of its spin. Another theory, advanced in 2005 by the original crash investigator, 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
