A sad day in the history of America's part in the space race.  On this day in 1967, 3 brave men died while training on the launch pad in a capsule simulator, this tragedy changed many things things, from disaster came progress and most likely saved countless lives.  
Rest In Peace Grissom, White and Chaffee.
