Black line ~ Chemtrail.wmv

original audio was replaced because of copyright issues, I kinda like the new one UPDATE: i have noticed around the time of 0:55 secs there appears to be an object that streaks across the bottom of the video, appears to be moving very fast and on freezing it seems to be bulky box looking... any ideas?? 28th May 2010 Evening time East coast England. I was filming Mr Chemtrail when a black line suddenly started to appear directly ahead where the plane was flying, i had never seen this before i caught it. I dont think its a shadow because shadows dont work like that.. think about it. Sunlight can do beams and columns through breaking cloud.. a chemtrail/contrail/whatever would not create a perfectly enclosed column of shadow .. other light would interfere further down with the shadow. Please comment. Thanks ..Im not sure
