i`ve a feeling that soot , or impurities in the exhaust, actually form the `seed` around which ice crystals can grow...
Due to the combination of vortexes and water produced by the engines (+ that in the air already)...

Yea, i remember seeing a vapour trail coming off a rear wing on a formula one car once...
(no-where near the engine exhaust)
This was clearly the vortex creating a low pressure in which moisture condensed out of the air..

(a bubble chamber in effect)...
