So in further discussion, the original storyboard for the sequence was posted. Looks fascinating!

Also it appears the crew used this damaged jet pack for the scene that did make the film where Han accidentally smacks it and sends Fett to his doom. Looks like they packed pyrotechnics in the hole. Also interesting, I never realized the SE used an alternate angle or take of Han hitting the jet pack. But both the original and the SE appear to use this damaged version. (Worth mentioning that this area has a clear patchwork repair in the jet pack’s more recent appearance on Disney+).

And finally, a clean image of the prop without all the captions and screenshots pasted on top of it.
