Pavel Romanovich Popovich (cyrillic Павел Романович Попович), born October 5, 1930 in Uzin[?] was a Cosmonaut who commanded two space flights, Vostok 4 and Soyuz 14[?].
In 1960, he was selected as one of a group of twenty air force pilots that would train as the first cosmonauts.
He was originally selected to command the Soyuz 2 mission, but following the accident that killed Vladimir Komarov, that mission was launched without a crew.
He retired from the space programme in 1982.
