The cross-hatches are almost impossible, given that they suggest that the wind isn't blowing in any direction at the altitudes they occur at. Looks like photoshop for the win. The satellite photos show parallel lines hundreds of miles long and almost perfectly straight. Ditto.
Photoshop? I took the first 6 pictures with my phone. The fact that you don't believe the photos in this thread are real is actually fucking hilarious. Look up every once in a while.
Some of those are con trails and aren't natural. The first pic looks like a weiner. I like the second one quite a bit.
I'm more of a nimbus man myself, but I dig a nice cirrus formation now and again. The vapor trails do nothing for me, though.
