There might. Metallurgists can discern the darndest things with their sections and microscopes, about the metal grain size and orientation. I'm not one, but have seen some of the things an expert witness metallurgist was able to say. The pattern of melting, how fast it cooled afterward, whether the surface vaporized or remained liquid, different metals in an alloy that melted out at different temperatures and fractionated revealing the melting point, stuff like that, I am guessing they perhaps might be able to give opinions on.
Nice
Congrats newbaker!
The chemtrails are different from contrails.
Chemtrails are distinctly persistent, and they spread afterwards, sometimes into a dense blurry haze that can sometimes produce oily-looking rainbow refractions if the light strikes them at the right angle.
Contrails, by contrast, dissipate rather quickly. Usually by the time a high-flying plane crosses the sky, from the viewer's standpoint its contrail on one side of the horizon is completely gone and the portion of the contrail overhead of halfway gone.
Chemtrails often form a heavy grid criss-crossing the entire sky and they persist and spread.
Even though I posted about it in response to someone, I'd rather drop the subject right now, as this topic usually serves as a slide. There will come a time to discuss it but now's not the time.
Anon. I have lived long enough to have vivid memories of how the jet trails USED to look 50 years ago when they were purely contrails. Your comment is invalidated by my own personal experiences over my lifetime. Younger people do not have memories of something they haven't seen. They attribute this artificial phenomenon to a "range of normal atmospheric behavior" because they don't realize the "range of normal atmospheric behavior" has drastically changed. I can say for sure that the chemtrails picked up in earnest where I lived, sometime in the 1990s.
I'm sure you mean well, but sorry, that's a fail.
