I personally do believe they are spraying.
I would love to know what and who are in command of these affairs, i do have an airport just outside my town (Cessna) that is quite large. For about 6 months they have been flying and doing test flights at night, my town has about 5000 people and to hear 2 of them fly right over your house at 2 am is something that makes you yell at them! hahaha i just thought of myself running outside and giving the old man fist shake at some black helicopter
Never have i seen a chemtrail though.
