In fine condition, with expected wear from use, which includes some scattered stains.A decorated pilot in the Soviet (Russian) Air Force, Onufriyenko was selected as a cosmonaut candidate in 1989 and later served as an integral member of four missions—Soyuz TM-23, STS-108, Expedition 4, and STS-111. He was a veteran of two extended spaceflights—aboard the space station Mir in 1996 and aboard the International Space Station in 2001-2002—which enabled him to accrue over 389 days in space and a total of eight spacewalks.
