Lately in my area I've been able to see big jets in my area leaving perfectly normal contrails at the same time the planes laying chemtrails are doing their routine. It's clear that the 'normal contrail' planes are flying far higher than the 'chemtrail planes'. This implies the chemtrails are occurring in the troposphere instead of the stratosphere.
I guess those lawsuits really did leave that nigga broke. I've got bums on the street here that look better than him.
The contrails I see are very short. Maybe 10 plane lengths long and just dissipate beyond that. Just like I remember from my childhood in the 60's/70's. The chemtrails on the other hand stretch horizon to horizon most days.
You'll have to consult industrial light and magic on that one.
