Went on ST once yesterday (7/21), and the CM during preflight said we'd need the lap belts for when we were flying upside down!?! After a couple of guest comments ("How can you tell, in space?") the CM mentioned something about a change having been made. Sure enough, when approaching the Death Star, it looks like a single shot was replaced, not requiring a change in the simulation, but enhancing the effect of one of the banking maneuvers, and explaining the 'upside down' comment. I've been on the ride enough to think I would have remembered the shot if it had been there before.
Can anyone confirm the change? If so, might there have been other shots augmented/changed? (Perhaps the projection has recently been switched to DVD, giving them the opportunity to do this. (I didn't notice a change in the projection's quality, however.))
