Driving west on Interstate-80, I saw scores of the same jets traveling east or west. Throughout the entire trip, the white haze around the skyline was visible for as far as the eye could see. Likewise, the chemical clouds were everywhere. East of North Platte, Nebraska, the sky was completely blanked out by synthetic clouds. One place, west of North Platte, where the chemclouds had a comparatively sparse coverage, I saw jets traveling north and south, in addition to east and west.
Some people claim to see rainbow colors within certain chemclouds.
I have also seen them. Rainbow chemclouds are sometimes seen when they are in close proximity to the sun. Most eye-witness accounts, including most of my own, mention the use of polarized sunglasses to experience this effect. West of North Platte, Nebraska, I saw some striking examples of rainbow clouds, with or without glasses of any kind. The rainbow clouds had large areas of pinkish-purple, green and orange, arranged in large blotches or bands within the cloud.
