Looks like a flying grain bin. On the other hand, it has very nice thrust vector control!
iirc it was built by a company that makes water towers so not too far off.
Glorious indeed. The shape reminds me of Boba-fett's ship from starwars.
Notice the flame turning red before landing? Did the mix become rich, or the flame cooler?
Presumably they need to run at a very low throttle to land. My guess is the engine doesn't run well at such a low throttle, and in fact they might have to deliberately make the mix very rich to keep the combustion stable.
