Cloud vs. Chemtrail - HARD CONTRAST

Where do CON-trails form?

Contrails are human-induced clouds that only form at very high altitudes (usually above 8 km - about 26,000 ft) where the air is extremely cold (less than -40°C). Because of this contrails form not when an airplane is taking off or landing, but while it is at cruise altitude. (Exceptions occur in places like Alaska and Canada, where such very cold air can sometimes be at or near ground level.)

What are CHEMtrails?
Caught on camera, flying through the epitome of cumulus clouds, at LESS THAN 8,000 FEET, are aerosol-spraying air tankers. For your relatives and fluoride-friends, this is good to teach them and SHOCK them (if possible) into getting ANGRY at their "government" for emitting 'CHEMTRAILS'. Military Industrial Complex in full and total effect.
