[[Soviet space program conspiracy accusations]] suppose that [[Yuri Gagarin]], first cosmonaut (astronaut) and head of Soviet "moon" team of cosmonauts, died during this alleged unsuccessfull first L1 manned mission around Moon onboard Zond 4, not in officially announced crash of fighter on 27 March 1968. But to this time L1 spacecraft was not ready for manned missions after all previous 4 uncussessfull unmanned test starts although this mission really was a first flight of L1 spacecraft under open designation "Zond". |

Zond 4, a formal member of the Soviet Zond program and unmanned version of Soyuz 7K-L1 manned moon-flyby spacecraft, was a short flight that was one of the first Soviet experiments towards manned lunar spaceflight. It was launched to test the space-worthiness of the new capsule and to gather data about flights in circumterrestrial space. It was deliberately launched away from the Moon either to avoid trajectory complications from its gravitational pull, or, according to NASA, probably unintentionally.[1]
After launching on March 2, 1968, it reached 300,000 km before coming back down. Operators attempted to bring it in with a skip reentry, but they made the angle too steep and it ended up plunging into the atmosphere early over West Africa. When the spacecraft reached on March 7 an altitude of 10 km, a self-destruct mechanism was detonated by Ground control, destroying the spacecraft over the Gulf of Guinea.
