You know, it's true, there's no way that two missiles from an X-wing could possibly have blown up the entire death star. First of all, if you look at the leaked planetary security holo-recording footage, you can see the proton torpedoes turning a 90 degree angle as they enter the so-called "undefended exhaust port", which proton torpedoes JUST CAN'T DO; and that's another thing, how come there was never any mention of an exhaust port there until after the attack, pretty CONVENIENT for them that all the evidence was destroyed! Engineers that worked on the station have actually said that the thermal vents for the main reactor are only in the equatorial trench, and at the poles. Pretty hard to explain how not only was there an undocumented weakness in some random trench in the north hemisphere of the death star, but how the rebels were able to find it? Sure seems like there was more involved; maybe the imperial government *wanted* the station destroyed. There is evidence that some key high-ranking officials were told to "delay" their travels to the death star.
Seriously you guys, you should watch this documentary called "Loose Credit Tokens", it really opened my eyes.
