   According to this, the Saturn V did not throttle down for Max Q.   
      
   'The Saturn V's first-stage engines don't throttle, so there's no "throttle   
   bucket" and no "go at throttle-up" call. One of the first-stage engines is   
   shut down late in the burn, but that's to limit maximum g-force for crew   
   comfort, not for Q limiting.'
