Yuri Gagarin

Rumors that he was drunk during his fatal flight are incorrect. He passed two medical examinations before the flight, and post-mortem tests found no evidence of alcohol or drugs in his system. A new theory, advanced by the original crash investigator in 2005, hypothesises that a cabin vent was accidentally left open by the crew or the previous pilot, thus leading to oxygen deprivation and leaving the crew incapable of controlling the aircraft. The Russian press reported he stayed with the aircraft to avoid it hitting a school, although this may have been apocryphal.

To commemorate his feat as a cosmonaut and being the first human in space, a crater on the moon is named after him. In July 1971 when the crew on Apollo 15 visited the moon, they left a plaque in memory of 14 men, Russians and Americans, who died in the struggle to help human-kind into Space. Gagarin was one of those names.

Gagarin was chosen as the backup pilot for the Soyuz 1 flight, the first flight of a program that was intended to put a Soviet cosmonaut on the moon by 1968. The flight was made by team leader Vladimir Komarov, and the launch of Soyuz 1 was opposed by Gagarin due to safety concerns.

Gararin was right: the Soyyz I capsule crashed after re-entry on April 24, 1967, making Komarov the first person to die during a space flight. After the incident, Gagarin again was banned from participating in the manned space program as an active cosmonaut. He was appointed deputy training director of Star City.

He was appointed a deputy to the Supreme Soviet in 1962 before he went back to the Soviet cosmonaut training facility, Star City, where the extremely bright Gargarin worked designing reusable spacecraft. He eventually was promoted to the rank of full Colonel of the Soviet Air Force. His celebrity was still so great, the Soviet government refused to let him return to space, though he eventually was chosen as one of the astronauts for the Soviet moon landing program. Though he had been trained as jet fighter pilot, his superiors limited his flight time so as not to lose one of the USSR's greatest heroes of the Cold War period.

Yuri Alekseyevich Gagarin became the first man to enter deep space on April 12, 1961, when the Soviet cosmonaut made a flight that orbited Earth lasting one hour and 48 minutes in his Vostok 1 spacecraft. This accomplishment made the smiling Soviet pilot internationally famous as the first man to venture into space, the final frontier.

The feat beat the Americans, who put Alan Shepherd into space in a sub-orbital flight on May 5, 1961, and did not have an astronaut orbit the earth until John Glenn accomplished the feat on February 20, 1962. The perpetually smiling Gagarin, who was promoted from senior lieutenant to major in the Soviet Air Force and was awarded the honor Hero of the Soviet Union for his accomplishment, became an international celebrity.

He made many trips to foreign lands, including three to the United Kingdom, to publicize the Soviet space program that, since its inception with Sputnik in 1957, had been more advanced than that of the United States. Thus, Gagarin was a prime pawn in the propaganda wars between the two countries at the height of the Cold War.
