That video is cool, I’ve never seen a plane do that.
I was thinking about a similar issue with the Falcon in ANH where Han says ‘Full reverse’. It is never shown how the Falcon goes in reverse, but I expect it would have to be something along these lines where the plates along the engine move down and angle the thrust forward.
So basically, my approach in this case is to run with the idea that G.L. and company would have wanted more moving parts on their sets, but they were simply limited in this respect. Another one is zero-g. I’m pretty sure that if filming zero-g scenes were available, they probably would have done so. Today’s “Star Wars Lore” is filled with all kinds of details that authors and enthusiasts filled in, which formed this “cannon universe” , which disney does or does not follow depending on the detail, and many of these details are things like, how does everyone have gravity in their fighter, how do speeders float, what is that prop on someones belt, etc.
Since it’s supposed to just be a cheeseball movie set, with plenty of coolfactor if you are willing to be understanding, it’s fun and entertaining for me, just like more popular fantasizers, to pitch ideas on how things might “really be”. In order to do that, I have to ignore “canon” completely. I don’t agree with even one lightsaber concept (i have my own), and I just think there’s not gravity for so many scenes that had gravity. And effective recently, I’ve decided that the engines in the film just work like normal engines today. Some are obviously able to double as jets or rockets, but mostly engines in Star Wars are just rockets.
