You could have a road which goes of a cliff and heads straight down 180deg but the car wouldn't be driving anymore but falling or if was a James bond car, wings could pop out from the undercarriage and the car could become a glider

So. Back to square one which was the problem for a few of you. Vertical contrails. That is what they are. I am well aware that a jet, or an ultra lite, even a skateboard can go in many directions. The point is they are much more vertical than horizontal. This was simply about ( left to right) horizontal or (top to bottom) vertical. that is all. It only went this far because if you read or reread the first two pages of the thread , the boys are telling me its not what I think but what THEY think. I disagreed and I was right..

I admit I was wrong, have looked at your photo just for few seconds the last time
BUT YOU ARE RIGHT this trails are vertical !! going strait from bottom to the top
is there any air-force basis near where this picture has been taken?
looks to me like there was two plains pulling up like rockets
if you look closer you can see a twist they made on the end
have no other explanation

Vertical Chem Trails ( What will they think of next? )

This video also has a nice illustration of "vertical" contrails around 1:30
But notice they are only "vertical" when they are lined up with the camera. As they drift away, they are no longer vertical.
In fact, you can tell its just a horizontal set of contrails, moving with the wind.

Are you saying the jet to the top left isn't climbing?
