I think that the reason they had to go in via a "back door" instead of blowing the place to bits from space, might just of had something to do with their target was the shield generator that was preventing any one attacking them from "outside" the shield.....\ said:....Nowhere is this effect more obvious than the shield generator scene in "return of the jedi". Why was it necessary for Han and Co. to go down to the forest world to 'clandestinely destroy the generator complex -through the back door, miles away, b.t.w.'?, when the alliance could easily have bombarded the installation from orbit (they brought enough capital ships). Or if you don't like that, why couldn't they have detailed a detachment of A-wings to go down and do the job, it's not like they'd be missed. (I'm really just getting started on all the errors I've been finding); as a result, I have coined a new term. "Lucasism": not because it's logical, practical or makes any kind of sense, but because it would look "cool".
