Which Russian cosmonaut became the first to fly aboard a Space Shuttle on STS-60?

Sergei Krikalev became the first Russian cosmonaut to fly aboard a Space Shuttle on STS-60.

Krikalev launched with five American crewmates aboard Discovery on February 3, 1994. The eight-day mission was the first flight of the Shuttle-Mir cooperation program and an important early step in post-Cold War U.S.-Russian human-spaceflight collaboration.

Krikalev had already completed long-duration missions on the Soviet and Russian space station Mir. His backup for STS-60 was Vladimir Titov, who later flew aboard Discovery on STS-63, the second Shuttle-Mir mission. That reversal is a frequent source of confusion.

During STS-60, Krikalev participated in joint medical and radiological investigations and used amateur-radio equipment to contact operators in Moscow. He later flew again on the Shuttle during STS-88, the first International Space Station assembly mission.
