yerssot, I think that you must be on crack for actually believing what you are saying. There is NO WAY that that is the same thing as the "exhaust pipe" of the first DS.
Remember IV. "The shaft is only two meters wide, so you'll have to use proton torpedos." Remember?
Okay, so how wide is the Millenium Falcon? It's at least 10 meters wide. The Empire wouldn't built a bigger shaft unless it had a different purpose. Case closed.
Case opened
I just found an old, and VERY ugly little pupet of the Emperor with a little card of the Death Star on it,
it says that the Emperors first concern was the exhaust-pipe, so there wasn't one in ROTJ.
So guess I was wrong, though I was pretty sure about it.
btw j212g: I don't take that!!! Please, leave that language, where I come from saying such is a big insult
point noted. Just to point out, in Leuven, Belgium saying such is one of the biggest insults so PLEASE don't say that. (btw that is only in Leuven)
If I didn't found that card I still wouldn't belief it.
To come back on plans that are flawing; was Vader on the DS a good move? Didn't he screw up with his flight, I mean could he do better?
