These are a sample of the kinds of contrails which are in question and what people are wondering about.  People who have seen these types of contrails, have reported upper respratory problems, fever, and flu-like symptoms.  These types of contrails are being painted on the daytime sky around the world, from pole-to-pole.  In the previous pages you have seen E-Mailings, and posted Newsgroup messages from alot of folks who have witnessed these contrails and say they take quite a long time to dissipate.  This may all be a crock...but come to your own conclusions...
