Today the skies over Colorado Springs are being sprayed and they are not even trying to hide it. The jets are flying East to West and West to East. As they approach the city from either direction there are zero contrails behind them. As soon as they are over the city, they lay down a thick trail that expands into very wide clouds. It totally stops as soon as the jets reach the other edge of the city. I have watched a half a dozen jets do this today with binoculars, and they are not changing altitude at all.
