Artoo butts the golden droid over the edge and steps off himself, tumbling toward the sand.
But in Attack of the Clones:
ARTOO uses his rocket jets to fly up and into the factory.
Why didn't R2-D2 use his jets in RotJ instead of ending feet up in the sand?
Update: I am looking for an in-universe explanation. From an out-of-universe perspective, R2-D2's rockets had probably not been created yet by the writers when RotJ was filmed. Did this ever get an in-universe explanation? For example, were R2's jets and/or stabilizers damaged and never repaired? Did Captain Antilles sell them to junk traders in exchange for fuel sometime after Revenge of the Sith?
