This cloud was seen at sunset in the western part of the sky in Portland, OR on April 23, 2012. It seemed quite odd, but made for a beautiful photo!

That straight white line? It is strange..
You have recogized a chemtrail. Googel Rosalind Peterson. she has a web site that & a video about this. also, there was a symposium in Belgium 2010. Case Orange. There is both a document online & a video called “Case Orange” We are being exploited by the military
You may be right (although I am quite skeptical of the theory to be honest) but, even so I have never seen a chemtrail/contrail/cloud that looked quite like this one…It was truly an odd sight.
