The Falcon is often connected to the Kessel Run, a pathway from Kessel past the Maw Black Hole Cluster used by smugglers to transport precious Glitterstim spice. Solo in A New Hope brags that the Falcon made the Kessel Run in "less than twelve parsecs". As this is a unit of distance, not time, different explanations have been provided. In the Expanded Universe, it refers to his ability to move the ship closer to the Maw's black holes and therefore cut the distance traveled. On the A New Hope DVD audio commentary, Lucas comments that, in the Star Wars universe, traveling through hyperspace requires careful navigation to avoid stars, planets, asteroids, and other obstacles, and that since no long-distance journey can be made in a straight line, the "fastest" ship is the one that can plot the "most direct course", thereby traveling the least distance. The novelization backs away and changes the line to "twelve Standard Time Units."
