...I was given an unscheduled vaccination at work last week . I usually get monthly booster shots for chemtrail immunity since I help load the black helicopter sprayers flying out of the local FEMA camp but this inoculation was not announced beforehand . I guess now I know what it was for and I hope it works because the scuttlebutt in the workplace says the illegal alien contagion is like ebola on steroids .

what is idiotic is when folks don't recognize the difference between a contrail (which dissipates within minutes) and other trails which spread and spread and do not dissipate (ie: cool down and not be visible beyond this returning to the temperature of the surrounding air),..
but, I understand, sadly, that may be beyond some folks ability to comprehend
It is well established by atmospheric scientists that contrails can not only persist for hours, but it is a perfectly normal characteristic for them to spread out into cirrus sheets. The different sized ice crystals in contrails descend at different rates, which spreads the contrail vertically. Then the differential in wind speeds between altitudes (wind shear) results in the spreading of the contrail across many miles in the sky. This mechanism is similar to the formation of cirrus uncinus clouds. Contrails between 25,000 and 40,000 feet can often merge into an "almost solid" interlaced sheet.[29] Contrails can have a lateral spread of several kilometers, and given sufficient air traffic it is possible for contrails to create an entirely overcast sky which increases the ice budget of individual contrails and persists for hours.[30]
