So I was looking for more info the female fighter pilots from the Star Wars Universe, and there’s this video from the Star Wars Celebration: Europe in 2013 of the unedited (and cut) scene from Return of the Jedi that had actress Vivienne Chandler in an exchange with another X-Wing pilot, which I found via this article. Also, as of August of this year (2014) there are scenes of Chandler as the X-Wing pliot in the ebook version of The Making of Return of the Jedi? Which you can get here.
That article also mentions who I was thinking of, which is the one line of dialog that actress Poppy Hands had in Star Wars as an A-Wing pilot (“Got it”) being dubbed with a male actor’s voice in post (the article says it was probably an accident), and apparently there’s footage on the Blu-ray release of Star Wars featuring Poppy Hands as the A-Wing pilot and the older “someone’s badass grandma” A-Wing pilot (as best I can tell, actress unknown, but if anyone has more info that’d be neat).
There are other articles but they all have more or less the same info
