Leonid Kadeniuk

Kadenyuk was a Soviet military pilot. He began his service in the Soviet Air Forces and was selected in 1976 for the Soviet Cosmonaut Corps being on a team of test pilots of the Soviet new space shuttle Buran, but was removed after marital issues. He was allowed to rejoin the Cosmonaut Detachment several years later. With the break-up of the Soviet Union, Kadenyuk remained in the Russian Space Forces and adopted Ukrainian citizenship. In 1995, during the preparation of the first Ukrainian space mission, he volunteered to take part and returned to his homeland.

In the 2002 parliamentary election, he was elected to the Verkhovna Rada in the list of pro-Kuchma United Ukraine Bloc. Later, Kadeniuk joined the "Trudova Ukrayina - Industrialists and Entrepreneurs" faction, but had not been politically active. He worked within parliament's Committee on Defense and National Security.

Asteroid 399673 Kadenyuk, discovered by astronomers at the Andrushivka Astronomical Observatory in 2004, was named in his honor. The official naming citation was published by the Minor Planet Center on 5 October 2017 (M.P.C. 106504).

In the 2006 parliamentary election, Kadenyuk was #3 in the electoral party list of Lytvyn's People's Bloc, but the block won only 2.44% of the popular vote (short of the required 3%) and no seats in the parliament.

Kadenyuk died on 31 January 2018, three days after turning 67. He was interred in the central avenue of Kiev's Baikove Cemetery. On February 2, 2018, the farewell ceremony occurred in Kyiv in the Club of Cabinet of Ministers of Ukraine building.

In September 2018 Chernivtsi International Airport was renamed after Kadeniuk.
