Important question…
In ROTJ does Grey Leader die then re-appear during the finale?
Possible, as they may have shot the ending before deciding which pilots to blow up. Or it’s another actor wearing the uniform and they didn’t alter the details?
But are we talking OT or SE version? The SE added a lot of shots to the Endor celebration. Some of those are obviously alternate angles or takes, but the shots of rebels and Ewoks celebrating on the ground might be 1997 footage.
