I doubt it since it isn’t in the script but just Ben Burtt recording himself in a church or whatever it was. I think it’s something very simple.
Well, yes, that’s kinda what I meant. It could just be something he recorded at an airbase, or something he swiped from an old movie, etc. I’m sure they made sure to record/find something that wouldn’t sound (too) out of place in a starship hangar setting, but I was never suggesting it was scripted. Of course it could just be something Ben Burt made up on the spot that he felt sounded sci-fi-y and then just added enough echo and electronic crackle in post to make it borderline unintelligible. Had this been any other movie than SW I doubt we would even bother to try an analyse this incidental background noise in the first place.
