Ok, first, colblair, no, that's not an alternate ending. Blair is gone for now, and most likely dead, but OSI got rid of him in a way that'll let them bring him back.
Second, like the other guys said, I wouldn't press this subject further. It'll most likely transform into a thread with over 200 posts, and people engaged in flame wars left and right.
Third, like TC, you could read the Jump FAQ, and you could also try and get the WC Confederation Handbook. It has some prety good descriptions of different drive systems.
