Star Wars: The Original Radio Drama, Episode 12, "The Case for Rebellion"

The Case for Rebellion

The Millennium Falcon arrives at the Rebel base on the fourth moon of Yavin - a base which now has mere hours to prepare for an attack by the Death Star. Luke, still mourning Ben’s death, volunteers for a Rebel attack on the huge space station - something Han feels is a suicide mission, especially given Luke’s lack of combat flying experience. For his part, Han intends to cash in his many favors and get out of the Yavin system before the Empire starts destroying planets, and his bluntness startles his newfound comrades. Luke tries to explain that the Empire will clamp down on all trade, legal or otherwise, but Han is sure that he and Chewie can survive, and after reaping his reward, blasts off for safer havens (x).
