S84-37532 (18 July 1984) --? Robert B. Thirsk, backup payload specialist for 41-G appears to be shaking hands with an unoccupied extravehicular mobility unit (EMU) during a familiarization flight aboard NASA?s KC-135 aircraft. Thirsk, representing Canada?s National Research Council (NRC), serves as backup to Marc Garneau on the seven-member crew for Challenger?s October 1984 flight.
