This is an interesting documentary made by Discovery Channel in 2007 - they explore chem and/or contrails and the various theories that have come from the relatively new phenomena of watching airplanes paint our skies.
Can metals and toxins be found in jet fuel? Can aluminum be found as an additive to ordinary jet fuel?
And if additives aren't in found in fuel, does that necessarily mean that nothing is being sprayed by other means?
