Acton listen to a briefing by a crew trainer (out of frame) during emergency egress training for members of the Challenger's next crew. Later, the seven crewmembers used sky-genies to practice quick egress from a potentially troubled Space Shuttle craft. They are standing near the crew compartment trainer in the Shuttle mockup and integration lab at JSC.

Other Challenger crewmembers egressing the spacecraft are, left to right, F. Story Musgrave, mission specialist; John-David Bartoe, payload specialist; Roy D. Bridges, Jr., Karl J. Henize, mission specialist; Loren W. Acton, payload specialist; and Anthony W. England, mission specicalist. Fullerton, commander, earlier successfully landed Challenger on a Mojave desert dry lake bed. Three years ago, Fullerton was pilot of STS-3, on which the Columbia's scheduled Edwards landing was moved to New Mexico because of weather and runway conditions here.

S85-29498 (June 1985) --- The crew members of space shuttle mission STS-51F have chosen as their insignia this design by Houston artist Skip Bradley. The space shuttle Challenger is depicted ascending toward the heavens in search of new knowledge in the field of solar and stellar astronomy, with its Spacelab 2 payload. The constellations Leo and Orion are in the positions they will be in, relative to the sun during the flight. The nineteen stars signify that this will be the 19th STS flight. Crew members for the mission are astronauts C. Gordon Fullerton, commander; Roy D. Bridges, pilot; F. Story Musgrave, Anthony W. England and Karl J. Henize, mission specialist; and payload specialists Loren W. Acton and John David Bartoe. The NASA insignia design for space shuttle flights is reserved for use by the astronauts and for other official use as the NASA Administrator may authorize. Public availability has been approved only in the forms of illustrations by the various news media. When and if there is any change in this policy, which is not anticipated, the change will be publicly announced. Photo credit: NASA
