Read all about it here.
1) Why were a handful of rebel fighters able to penetrate the defenses of a battle station that had the capability of destroying an entire planet and the defenses to ward off several fleets of battle ships?
2) Why did Grand Moff Tarkin refuse to deploy the station’s large fleet of TIE Fighters until it was too late? Was he acting on orders from somebody to not shoot down the rebel attack force? If so, who, and why?
3) Why was the rebel pilot who supposedly destroyed the Death Star reported to be on the Death Star days, maybe hours, prior to its destruction? Why was he allowed to escape, and why were several individuals dressed in Stormtrooper uniforms seen helping him?
Important questions, indeed. I demand answers.
