Ok well the first video I do not beleive at all. Anyone can make any of that up. And with how much plane traffic there is these days, I'm surprised there aren't more criss-crossing patterns in the sky from contrails, which those obviously are. Contrails can linger for a while because of the temperature, humidity, winds, and aircraft exhaust characteristics. Secondly he says that the Chemtrails are possibly caused by the HAARP system which has nothing to do with it. HAARP is a radar system that uses microwave energy. That video is pure conspiracy crap. I can go and say the goverment is putting vaporizing crystals in the road salt when it snows to control our minds and it'd be just as beleiveable as that video.
The second video I stop 1 minute in. You know why? Because that guy has absolutely no proof that these "chemtrails" are what landed in his jar. He could've said aliens flew over, waved hi, then sneezed and barium came out of their snout like noses and landed in his jar and it'd that story would hold up just as well. That's kind of sad that a news department even ran that. I can crap in a jar and take it over to NBC10 and tell them its an alien egg and it'd be just as reputable as what that guy is saying. Barium could've been in the soil in farms surrounding that hick town of his and the wind blew it into his jar. Did they test for that? No. The guy wants his 15 minutes.
