Read the patents yourself
Chemtrial related patents they most certainly are using metal oxides in the atmosphere every day, look at that sites home page, the html stinks I'll give you that, but if you deny that this is going on I'm certainly not the idiot here. They have the patent number, you can look them up yourself. But try this sometime, on a clear morning, watch the sky out of your office windows, watch the trails from the planes begin to spread out slowly, until the entire sky is white, not with clouds, but with trails made from planes, and only that, it wont happen every day, but it does on alot of days, more than it doesn't actually. Folks at work used to make fun of me, now, not a single one of them denies the sky here in our state is made cloudy consistanly by the trails being left behind by jets, I proved it to them over and over again, you can simply watch it happen. I challenge you do so.
