Amazing Chemtrails in North London, England Oct 2011. Must watch to believe

This was filmed by the mighty Nokia N8 on the 11th Oct 2011. On that very morning I vividly remember the morning started with such clear blue sky, it was like a summers morning with beautiful sun rays. When I left my house and looked up to the heavens I could not believe my eyes, aeroplanes after aeroplanes making all sorts of lines with what I know to be Chemtrails.
Soon after the Chemtrails dispersed into soft clouds and subsequently blocked the vital sun rays, beautiful blue sky was no longer vast and thus the Sun's Energy was reduced.
I must share the sheer beauty of the heavens being attacked by an organisation whom our government pay, to spray unknown substance to benefit our produce and yet there are no Farms in Haringey. The concern here is, the spraying continues and yet there is an increase in Asthma & Hayfever in our area, is there a link?
What is it all about, what is the true purpose?
