John Glenn during preflight training for STS-95

S98-06944 (28 April 1998) --- U.S. Sen. John H. Glenn Jr. (D.-Ohio) prepares to rehearse launch readiness procedures on the middeck of a crew trainer at the Johnson Space Center (JSC). Sharon Jones, involved in crew training, briefs the STS-95 payload specialist. When he lifts off aboard the Space Shuttle Discovery in October of this year and later lands in Florida, Sen. Glenn will be seated in a temporary middeck chair like the one used in this training exercise. The photo was taken by Joe McNally, National Geographic, for NASA.
