I have been researching the chemtrail phenomenon for over three years now and I am constantly asked the same questions, so to alleviate much personal grief and provide a singular source of accurate information I have created this FAQ for you to share, challenge, debate, and hopefully contribute to. Let’s dive in:
#1 There’s Barium and Aluminum in the Chemtrails
True.
Atmospheric Aluminum A2O3
The predominate source of anthropogenic aluminum in rain and soil samples are raining down from space, blame the rockets:
Each time a space shuttle is launched, the solid rocket boosters release 240 tons of HCl gas, 26 tons of chlorine gas, 7 tons of nitrogen dioxide gas, and 304 tons of aluminum oxide into the atmosphere. The resulting hydrochloric acid dissolves eight inches of concrete on the launch pad, raises the concentration of hydrochloric acid in nearby lakes to 3 M, produces massive fish kills in the ocean, and destroys the paint on cars. Leading chemists believe that the HCl is a major contributor to the holes in the ozone layer.

That’s right space fans, rockets! 304 tons per launch, 608,000 pounds of aluminum oxide. But wait, there’s more! Welcome to the future of aluminum: ALICE!
Rocket propellant has barely changed in the more than 50 years since the launch of the first artificial satellite Sputnik. But a new mixture of nano-aluminum powder and frozen water could make rocket launches more environmentally friendly, and even allow spacecraft to refuel at distant locations such as the moon or Mars.
The aluminum-ice propellant known as ALICE gets its kick from a chemical reaction between water and aluminum. Space.com 2009
The interactions between aluminum exhaust and water have been studied since 1962’s Project Highwater when Atlas rockets dumped 23,000 gallons of water into the ionosphere to make it glow (airglow).
Aluminum interacts with the ionosphere to produce airglow, as does water releases. It does not surprise me that ALICE combines the two, here’s why:
Also, the term “green propellant” is often confusing, as many assume a green propellant has no environmental impact. Such a propellant is generally beyond the realm of physical possibility. All propellants affect the environment in some way. For instance, all launch vehicles produce exhaust. The components of this exhaust can include soot, carbon dioxide, alumina, inorganic chlorine, water vapor, sulfates, and nitrogen oxides. All of these have an environmental impact, and may contribute to climate change, ozone destruction, or upper atmospheric contrails, depending on the atmospheric layer in which they are deposited; however, the severity and duration of the impact can vary greatly. Given this fact, a green propellant is more correctly viewed as one that seeks to minimize or eliminate a critical environmental impact in one or more of the four main areas. A green propellant is likely to have its own environmental impacts, which may be equal to the current technology in certain areas. For example, many green propellants seek to eliminate hydrazine because of its biologic impact, but they still present atmospheric or space-based effects. Aerospace.org 2011
Nano-particle Aluminum Steam
They are now using nano-particle aluminum to boil frozen water, putting it in ALICE rockets, and we have to consider the possibilities of this technology as it pertains to chemtrails:
Anthropogenic aluminum comes from rockets, very little comes from chemtrails if any, in my humble opinion.
Although rockets produce tons more aluminum than planes do, both are tiny compared to good ole dirt blowing up from the ground:
A LARGE SILICON-ALUMINUM AEROSOL PLUME IN CENTRAL ILLINOIS: NORTH AFRICAN DESERT DUST? 1995
During a summer atmospheric chemistry field project in central Illinois in 1979, unusually high concentration of Si, AI, and other earth’s crust elements were observed simultaneously in two series of 2-h aerosol samples collected at sites separated by about 20 km. The Si-A1 “event” persisted for about 32 h, and was accompanied by winds shifting from east through north as a weak low pressure area moved eastward across southeJrn Illinois, and a nearly stationary front moved back and forth across the study area. Comparison of aerosol Si/AI and Ca/A1 ratios during the event with those in possible sources showed that local soils, coal flyash, and A1 smelter emissions were unlikely sources of the observed plume, and focused the investigation on distant dust sources. Climatology favors north Africa over the western United States as a source of desert dust in summer.
