Hi, I just purchased, installed and really like this aircraft.  I haven't found anywhere as much problems like I did when I purchased the 727, which I have figured out all of the fixes for especially the sound.  Nice that they released this plain without having to mess around with the config files and reloading aircraft multiple times.  Anyway has anyone but me noticed that the contrails seem to be missing when flying the average 28000 ft?  I am, but I did notice some weird effect some distance below me.  I can only assume that for some reason the effects are miss aligned.  Can anyone help?  this kind of makes the simulation a little less realistic.
