First direct ascent trajectory for the Space Shuttle
These Extravehicular Mobility Unit (EMU or spacesuit) ID tags were sewn to the boots worn by STS-41C crewmate James "Ox" van Hoften as he worked outside the shuttle during two spacewalks. Together with "Pinky" Nelson, van Hoften performed the first in-orbit repair of a satellite, Solar Max. Running ahead of schedule at the end of the second EVA, van Hoften was given the go-ahead to to test fly the Manned Maneuvering Unit (MMU) jetpack in the cargo bay.
