In this material world, that which is in shade is either facing away from the source of light, or has something between it and the source of light. You know this to be true yourself if you are a normally-sighted, normally cognizant human being.
Yardstick's kindergarten attempt at bullsh*tting an optical illusion has just "proven" that an underlit contrail would appear to us as if it was lit from the top, not from below, and that the side facing us would be in shade ... Right? LOOK AT THE DRAWING. The sun hits the TOP of the contrail; the bottom, the only part we can see, must then be in shade. The thing isn't opaque and glowing all 'round like a fluourescent tube -- or shall we expect another few hundred photo "proofs" from Yardstick and others married to the "airplane" fantasy that indeed, it is illuminated very much like a flourescent tube, thank you very much, because .. .I know!! I got it! I got it! It's water vapor, that's it!!! Yeah, that's the ticket! That's why it (though not regular clouds) look as if it's bottom was lit when the sun was hitting it's top!
THEN he shows a photo of a contrail that is bottomlit, and appears the opposite of what his ridiculous drawing indicates. LOOK AT IT AND THINK!!! It's just absurd, and it's why most of the time I ignore all of these ridiculous "proofs." They are hamster wheels -- going no place. I take one look and again am aghast at how blatantly absurd the "proofs" are, and I am sad that so many people shrug and figure the "science" looks impressive and I don't want to be considered a paranoid kook ... so, I'll go with "airplane" for $500, Alex.
Folks reading Yardtick and the rest of these contrail "provers" posts need to stand up to "we are men of science!" intimidation with brain-draining, energy-sapping crap pretend "proofs." YOU have all the expert you need IN YOUR BRAIN. Look at the video, think in 3-D. The audacity of Yardstick with that lame-brained illustration is absolutely breathtaking. Just stunning.
Good GRIEF!!!!!!!!!

No, but as you mentioned, it's made of water vapor that disperses and reflects light, even light coming from behind, which allows it to appear almost internally lit when seen against a darker sky.
Check out the edges of the cloud in this pic. Its edges are bright because they're scattering the sunlight that's coming from behind:
Now look at these stills from the video. Doesn't the contrail look like it could be similarly backlit? It even shares the characteristic of being darker in the middle where it's thickest:
The faint shadow it casts in the sky is also consistent with it being lit from behind.
But I don't think the lighting argument is decisive because the light is coming in at such a grazing angle that it's hard to judge exactly what it's doing.
To me the Cargo Law webcam pic is the clincher.
Finny,
You need to take a little time off...
You’re inner ritard is showing.
People who believe the moon landings were faked will tell you the photos prove it. They say that all you need to see that they were faked in a studio on Earth is right in your brain.
People who believe the World Trade Center was brought down with planted explosives will tell you the proof is right there in the video. They say that all you need to figure it out is right in your brain.
BTW, I watched a National Geographic documentary where they dismantled every single piece of “evidence” that the Moon landing was faked. Then they presented the evidence to a prominent moon landing conspiracist. He not only ignored it, he told them it was obvious that the landings were fake because of a piece of evidence he had failed to debunk. In a vacuum, he said, the astronaut’s gloves would be too stiff to work. He even took out a vacuum pump and demonstrated his theory. Common sense. Science. Obvious to even the most casual observer, and anyone who says otherwise is carrying water for an evil government conspircy.
Now, I’m a big believer in intuition, but sometimes it fails us, tells us something was going on that wasn’t, and if we can’t plug in other facts and realize we misperceived, then we end up posting screeds about flourescent tubes and massive government photoshop conspiracies.
