What else was happening to our skies?

Though other projects have since piggy-backed onto this extensive covert program, environmental
consultant Mike Castle discovered the primary purpose behind chemtrails when he discovered a patent
for “Stratospheric Welsbach Seeding for Reduction of Global Warming”.
Filed by aerospace giant Hughes Aircraft Company in 1991, the patent explained that Welsbach
materials are oxides of metals capable of reflecting incoming sunlight. They also convert heat trapped
by greenhouse gases near the Earth’s surface into far-infrared wavelengths, which then radiate back
into space.
Cautioning that the resulting white skies may be unpopular, the Hughes patent nevertheless suggested
that these very tiny metal flakes could be “added to the fuel of jet airliners, so that the particles would be
emitted from the jet engine exhaust while the airliner was at its cruising altitude.”
Aluminum oxide can withstand temperatures far higher than jet engine exhausts. While highly abrasive
in larger sizes, a former Alcoa aluminum engineer told me that aluminum in the 10 to 100 micron sizes
called for in the sunscreen patent would simply polish jet turbine blades without harming them. (A
human hair is about 100 microns across). The engineer added that this “very fine, talcum-like” aluminum
powder would appear as a “pure white plume” in the sky.
All that remained to prove Castle’s conjecture was a scientific lab test of chemtrail fallout.
