Wow. Great post. To anyone not convinced of a fallecy, that would be sufficient to explain the direction of the contrail. Undeniably so.
But, as you can see in #144 -- comprehension has yet to occur in some places...
Do you remember what thread we were on when we did our bit -- starting with your post of the CBS night view across the harbor and ending with our starting to use Google Earth to establish azimuths? Got a link?
I just found a GE viewpoint frame in one of Mick's videos that matches that same night viewpoint. Cool independent verification!
...almost as cool as your LAX GE work!! ;-) .
