Remember that there is 5 years between ANH and ROTJ, so everything can change. I must say that I agree that I based the whole idea on loos ground, but if you are fighting a huge squadron and suddenly the shields fall out, the first thing I do would go in the exhaust pipe because it failed the first time, so the second time could fail also.
lol
Can anyone put the lines of Mon Mothma here when she is explaining the attack? My videorecorder broke down, so I can't see it.
I know she doesn't say: let's fly through the exhaust-pipe, but I can't remember how she calls the thing they fly through. (If you look at it: it devides the circle in 4 pieces)
I've lost track of this argument and I don't know who has said what but here IS what happened in the Death Star battles.
In ANH the death star trench led to the exhaust port. To blow up the DS you had to fire torpedos into the exhaust port. The torpedos travelled along until they hit the MAIN REACTOR in the middle of the DS. This caused a chain reaction and it blew the DS.
In ROTJ there was no trench and there was no exhaust port. It hadn't been built yet. It might never have been built. Instead, the rebels could fly right in and blow up the MAIN REACTOR.
Which I think is the same weakness.
In ANH when the rebel leader thinks he's blown up the DS and then say's "it just impacted on the surface", he's talking about what we see in ROTJ. His torpedos hit the part that the Falcon flies through. They never made it all the way to the main reactor.
