nice try, my friend, but in fact I HAVE done so numerous times and you are dead WRONG. When I photographed this bunch of So-called Contrails, I checked the FAA flight patterns, flights etc. nothing matched up, so I checked the local airports for the same 411-Guess what? Nothing there either...go figure. Then I said well I better check in with the good 'ol USA Military and see if any of their great air fleet were busy overhead...SURPRISE.....That was also a negative. So what is your take then? Canadian Geese farting in the sky??? Homing pigeons??? A flock of flying sheep shooting dry ice out of their butts? WAKE UP and SMELL THE TRUTH my friend. There are SOOOOO many NSF documents, and other evidence on their site (research grants, studies etc)which remove all doubt about the FACTS regarding the strange "Contrails" that DO NOT DISSIPATE, as a contrail does. Rather they fan out and end up blanketing the entire sky in a thick white "cloud". THAT in itself should have you questioning the validity of your argument.
