		<description>I suspect it looks like &quot;space&quot; as space is dark. 

You probably saw a shadow cast on a thin layer of cloud (or high altitude fog/haze) under the contrail. You see moon contrail shadows most often when the moon looks a bit hazy and often has a halo. See example:

		<description>I have seen a shadow under the &#039;contrail. Yet it looks like SPACE not a shadow. And there was no sun as it was night time, but there was a moon but it was not behind the contrail.</description>

		<description>There&#039;s been very little change in aviation jet fuel since jets started flying commercially - Jet A was first specified in the 1950&#039;s, and all of them are essentially kerosene, and the differences are mainly to do with how wide the &quot;cut&quot; is so how flammable they are.

the current standard for Jet A1 is available here - http://www.seta-analytics.com/documents/DEF_STAN_91-91_R6.pdf and a general history of jet fuels is on wiki at http://en.wikipedia.org/wiki/Jet_fuel</description>

		<description>Well great debate, 
to the haters that wanna tell people off for there veiws i say &quot; chill winston&quot;  everyone here has a valid point of some sort, wether its there veiw or just belief theres more to life than u know,
I seen my first   tunnel ( black path in front of plane)   a month ago with my boy, we were driving in the car when we seen it and stood in the middle of the road looking, it lasted 20 seconds and when we moved a few meters to one side it dissapeared, when we stood back in the innitial spot we seen it it was gone, what i seen was a tunnel in front of the plane that disipated as the plane flew its path into it, to me it looked a dark brown with a lighter section where the plane was entering as a pre determined path, the veiws you have to shadowing and other theories all sound good in theory, 
My argument is for you all to beleive one theory u are closing your mind to other possibility&#039;s, as good and basic your shadow theorys are &quot; de arre&quot; had a major point in regards to the changes of the world around us,

As for the chemtrails  ive been in the auto racing faternity for 20 years and public fuels have changed dramaticaly imagine the differance in aviation fuels and there makeup and how theyve  changed for environmental and other reasons, hence when i was a kid they would disperse quickly and were different, 

As for the puppet masters of this world if u had proof of this you&#039;d be dead, lol</description>
