They are just angry cranks. Its easy to make up a conspiracy, but, when asked to prove it, they scatter like roaches.
BTW, If you're still near the DFW area, go outside and look up. Here, near the LA/AR border, there are dozens of contrails -- with several that stretch from western horizon to eastern horizon.
Some of those have been in place for over an hour, are "rippled" like the "missile plume", and have spread out several miles wide by now. With contrail formation and preservation conditions this good, I wouldn't be surprised to learn that a significant fraction of the high clouds in today's sky started out as contrails.
My granddaughters are singing in a church Christmas musical this evening, but maybe I can get a few shots of some contrails in the western sky after sunset...
