Apollo 13 was called "The Successful Failure" because the three astronauts returned to earth alive and safe although they never walked on the moon.
Gene Krantz, Flight Director of several Apollo flights always wore a vest made by his wife, each one specific for each flight.
While at the Johnson Space center, I, too, wore a vest for a brief time. The vest I am wearing is NOT one of Gene Kranz's vests, but he did wear it. Thanks goes out to the volunteer who put the vest on me for a picture!
