I wish I understood the weird smoke effect. It's got to be some kind of pseudo-collision box thing happening that doesn't damage blocks (sort of like when a wheel spins on a surface). I had another ship do the same thing with a rotating thing-a-ma-bob I put on it for effect; it didn't do anything for the ship's popularity. Here's the link in case you're interested (you can read the B.S. I wrote about in the first note at the bottom of the description):
