Star Wars: The Original Radio Drama, Episode 13, "Force and Counter Force"

Force and Counter Force

As the Rebels launch their foolhardy attack on the Death Star, Admiral Motti tries to convince Grand Moff Tarkin that, as the space station’s commander, he holds enough power to challenge even the Emperor - and despite a warning that Motti’s suggestion is treasonous, Tarkin seems emboldened by the idea, enough that he declines the option of readying his personal escape craft. Vader personally leads the Imperial TIE fighter pilots to take on the approaching Rebel force ship-to-ship. The Empire’s crack pilots whittle the Rebels down to just a handful of ships. It will take only one Rebel fighter to reach the target ventilation shaft, fire a computer-guided torpedo into it, and destroy the Death Star - and before he knows it, Luke Skywalker is that sole Rebel, and Darth Vader makes it his personal mission to eliminate him (x).
