When Fenn Rau is first attempting to flee Concord Dawn, the throttle on the Phantom II's dash is pushed all the way forward, and Rau hesitates pulling it back, which would have accelerated the ship to hyper speed and abandoned Sabine, Ezra, and Chopper to the Imperial Super Commandoes. When the group is leaving the planet in the Phantom II at the end, the throttle is all the way back, and must be pushed forward to accelerate the ship.
Near the end of her battle with Gar Saxon, Sabine's jetpack goes missing for a shot but returns in the next shot.
