From the left are cosmonaut and flight engineer Sergei Krikalev, mission commander William Shepherd and cosmonaut Yuri Gidzenko, Soyuz commander. Behind them is the full fuselage trainer, one of the full-scale mockups used to prepare the crew for certain phases and contingencies of their shuttle return flight.
