I think it can be assumed that there are no guard rails on the carbon freeze chamber because the controls are manually operated
I wasn't referring to the fall Luke took. I meant the one Vader took when Luke knocked his ass off the platform during the lightsaber duel. You'd have thought there'd be a guard rail there... except the script required there not be one. So I go with it.
As far as blasters go, apparently you didn't pay attention when reading Shadows of the Empire
Oh I did, it's just that it's not a movie. If it ain't in the movies, I won't likely accept it.
That lovely book has been responsible for more bullshit explanations that we don't need than anything
Be that as it may, I'm just saying it's probably the best of the EU books and has the most "Star Wars" feel to me.
