What is the interest in that thing besides it being big? It's a boring, resource taxing, destructive burden.
Boats and couches don't cruise deserts in default world. Big planes get pulled around the ground all the time. Big planes even land in the desert, and! do so without getting stuck. The plane is not original.
"But doing a lot of work > originality! You're being a pratt, and-"
No, history is littered with things which took a lot of work, that were bad ideas and least forgivable, weren't original. Every Burn forum defends the plane with "lots of work", "what'd YOU bring" or "walk a mile in their shoes". Cut it out, those are the worst arguments ever.
Sit still. I'll have a original (...to me) idea in ten seconds.
Ok. Everyone cover their nuts, girls too, because the playa is going nuclear.
Build the top horizontal 1/4th of a submarine, on a concealed drivetrain that I can't bother to imagine. Scale reduced, we've had enough "big 1:1 thing" for now. But have recessed decking on top, so people can stand in it and get their drink'on. Safety railings, issue LED trim with emphasis on navigation lights (like a boat), climbable conning tower. Obligatory rave kit but if someone moops it plays the chorus of Donovan's "Atlantis" on loop until cleaned up.
A taxiing plane is a taxiing plane, just. Meanwhile the idea here is that while the boat's cruising around, from a distance, it looks like it's partially submerged in the playa. Thus we only need submarine topmost bits that stick out of the water. Call it the "Scarlet September" (all drinks must involve vodka), "Lonely Diver", "The Wet Spot" or something*. Boom, grant application. Also j/k.
A nuclear submarine for land deployment. Are you less than wowed? Well that's all you get for ten seconds. But is it an ordinary, sanitary, unoriginal thing you can see at any airport? Only as much as a boat or couch would be.
* does the plane have a name?
