This past weekend, I accompanied Miles O'Brien to the 50th anniversary of the Kennedy Space Center. In attendance were present and past KSC directors, NASA Administrator Charles Bolden, astronauts and space heroes of all eras—from Thomas Stafford to Cady Coleman—and many of the so-called "pad rats" who built spacecraft from the Apollo era through the Shuttle era. Miles delivered an amazing speech dedicated to those pad rats.
If you're familiar with traditional Japanese craftsmanship culture or you've seen the film Jiro Dreams of Sushi, you'll know why he calls them "The Shuttle Shokunin."
