oh boy smile will be fantastic!

i have been wondering about a couple of items ...

when a plane crashes ... is there anyway to keep at least a 'decal' of crash site present on the ground? and can the smoke, which right now appears a bit like a uniform 'vector' maybe in direction of wind ... be changed to a more fluid simple 'undulating animation' not necessarily tied to wind direction?

sorry if not the right time or place to ask - but have been curious if those types of moves are possible or not?
