You may familiar with supersonic aircrafts (and its land counterpart), but these objects are also capable of achieving supersonic speed (768 mph = 1236 kmph) or perform sonic boom when used / in use :
The plume is a crudely shaped cone with geometry nodes. I did mesh to volume and distribute points in volume, followed by points to volume. The first volume introduces some “turbulence” which contributes to the blobbiness, while the second one controls the distribution density of the points as well as the radius. Noise textures drive the density and blackbody temperature.
