Chemtrails Over the Skies at Earthday?

I have located a picture I took in June of 1977 in Pennsylvania on a day when there were an incredible amount of jet trails in the sky, so many the sky was nearly opaque. YouTube would not post the response I made with a flickr link, so I'm posting it here, see http://www.flickr.com/photos/22501544@N05/3464317… go to "all sizes" to see a larger version of the photo. The contrail shown in the video did continue to expand for a couple hours, perhaps 50-100% wider, before thinning out and disappearing. I've never seen one expand to cover the whole sky.

Chemtrails Over the Skies at Earthday?

I made the video mentioned in post #16 and found this blog via the comment posted on YouTube. As mentioned the video is at http://www.youtube.com/watch?v=wHsZWOOv-l0 At the time of the video, it was still quite early, around 7am. My impression is these condensation trails are just that, condensation. At very high altitudes the ices crystals can propagate quite a ways before eventually dissipating. Some days the temperatures and humidities are excellent for contrail formation and expansion, other days, the contrail immediately evaporate! I'm sure upon investigation that the planes "doing that" were normally scheduled flights, not a sinister plot by evil doers! I am long time weather observer and can say these "chemtrails" have been around for at least 35 years, more so on the East Coast around the busier flight zones.
