Thanks Joani,
I dont understand what it did, but now I have another 10 lines to look at. Mine does not show ground effects, but a VV you did on the top of page 315 (post 3141) shows a challenger that went all the way to kz and showed shipping movement, yet never showed ground effects anywhere. Does this seem strange?

PS I am going where ever you go. If the group meets in Vegas, I will make the time.
