Chirone::::: ,ha, i had forgotten to model the exhausts of the missiles although the big one in the middle is a external fuel tank i think,

basically for the clouds, make a nurbs sphere and stretch a bit, create a lambert and plug the cloud node(under 3d textures) into transparency, fiddle with the settings, try to get an all white edge as black will show it up,
i done this with bout 10 secs fiddling not the best example but they r quick to render unlike fluid clouds, u can make better clouds than this example i just dont have the time atm
