About Vladimir Komarov
Vladimir Mikhaylovich Komarov (Russian: Владимир Михайлович Комаров, IPA: [vlɐˈdʲimʲɪr mʲɪˈxajləvʲɪtɕ kəmɐˈrof]; 16 March 1927 – 24 April 1967) was a Soviet test pilot, aerospace engineer, and cosmonaut. In October 1964, he commanded Voskhod 1, the first spaceflight to carry more than one crew member. He became the first Soviet cosmonaut to fly in space twice when he was selected as the solo pilot of Soyuz 1, its first crewed test flight. A parachute failure caused his Soyuz capsule to crash into the ground after re-entry on 24 April 1967, making him the first human to die in a space flight incident. He was declared medically unfit for training or spaceflight twice while in the program but continued playing an active role. During his time at the cosmonaut training center, he contributed to space vehicle design, cosmonaut training, evaluation and public relations. In 1946, Komarov completed his first year of training at the Chkalov Higher Air Force School in Borisoglebsk in Voronezh Oblast.
