When the shuttle lifts off, what is used to make it turn and roll?
(roll/pitch? turn/yaw? you know what I mean...)
I would assume that the orbiter's aerodynamic surfaces are not used,
as they are not directly exposed to the air, and its not going
_that_ fast when it clears the tower and starts the turn, and I would
assume that the SSME's are not vectored, right?  Which one of these
is wrong?

BTW, I went to an Illini Space Development Society mtg here at the U
of Illinois, and saw a NASA tape about the shuttle trainer.  Mostly
not too exciting, but there was one really neat shot of one of the
CRT's used to simulate the view out of the windows during takeoff.
My thoughts went along these lines: "What's that silly cross-hatched
stuff they're showing now?  Why's it going sideways so fast, and whoops
what's that spike, hey its gone, it must have been the launch structure,
and wow look at the scenery and woah noooo dont turn over that far
you'll fall over, woah stop spinning, augh stop falling so far back!!!"
It honestly reminded me of some of the worst rollercoasters I've been on.
Must be one hell of a ride in the real thing!
