Interesting Contrails create five crosses in the Atlantic

[Mick West]

Very interesting patterns here:

http://earthobservatory.nasa.gov/IOTD/view.php?id=78154

That's Terra, the Aqua image is later:

The contrail segments are 200 miles long, and the centers ar about 70 mile apart.

It's not obvious how this pattern could have occurred.

I think it's basically showing five flight paths. Draw a line connecting the X's of the five sets of paths, along that line there is no N/S wind movement. To the east of the line the wind blows north, and to the west it blows south.

Given the displacements shown you could generate a vector field that would give consistent results like this. Still rather unusual.

Actually, if you look at a chart of North Atlantic flight tracks, you will see how these could be made. Look at that line off shore of North America, where you have all those points where aircraft go to on their flight plans, and then start out across the Atlantic, or where they arrive at and leave the oceanic part of their flight as they go towards their destination.

Very cool. I was over complicating it. I'll do some overlays tomorrow.

It seems to me that both explanations are correct. The planes appear to enter/leave the North American airspace at the fixed grid points. The directions of young contrails do correspond to the direction of flights between the States and Europe, whereas the directions of old contrails do not. There had to be a 180° change of the direction of wind between the east and west ends of the contrails. It is in agreement with the weather fronts in the area on the date:

Alternatively, these patterns could be a projection of the invasion plans by the orc general of Mordor, whose picture can be found below them:

So why would we be chemtrailing the North Atlantic?... Is the Azores getting a little uppity?

 

[MikeC]

Depopulation by poisoning the Grand Banks fishing areas??

Interstingly I've been doing some renderings of flight paths, and they actuall show that no strange wind patterns are needed for this. It's simply how they fly. Somewhat randomly across the atlantic, and then direct for those nav points and beyond:

Some parts of those "random" tracks may also be flight diverting around weather.

Those look like "AR" routes (also called Oceanic Routes or Atlantic Routes) as we used to call them. They're designed parallel to each other, flying waypoint to waypoint.

In late on this, but yes those at NAT TRACKS.

Could be Aslan.

Merging in this post from Jay:

I got this many years ago off the Dundee website, don't remember it's provenance exactly, but its pre 1999:

from my contrail gallery:

Also found this today: Suggesting the image is from 1987, with the ship trails from 1983 ?
