Oops - forgot. There is a scaling anim function already in FG and objects can certainly be scaled based on values in the property tree, so it should be possible to do it with Nasal. Looking at ufo aircraft, there should be transparency animation implemented as well (depends on speed in ufo

We could also simulate the condense effect by this (when in right combination of temerature and rel. humidity, water drops appear behind the engine). Texture for this puff should be a bit more transparent, but should vary as well. It should last for more than 4 seconds as well and should slowly
