Re: Geoengineering & Chemtrails **AWARENESS** (I'm back)
Duration of contrails depend on the humidity of the air at that particular altitude. Often the humidity levels very greatly between ground level and several thousand feet above. That's all I have to say about the "contrail hanging around too long" reason for thinking it's something malicious.
