Well, utmost, if the 'sky is toxic'...I guess you would mean the air we breath is toxic...then the people at most risk are those who are in
airplanes, since THEY breath that air more than anyone on the ground will.
Before you shoot laserbeams at me, perhaps you should understand about how air is introduced into the airplane cabin to keep you alive in flight. It
comes from the atmosphere around you, the same atmosphere that is magically producing lift (with help from the wings) to keep the airplane aloft.
At altitude, the cabin is pressurized, of course...in fact, more air is being pumped in than is needed, so we have a 'outflow valve' which modulates
to control the pressure. Where is the air coming from? The engine's compressor section...air is sucked into the intake of the jet engine, and
compressed thru a series of concentrically-mounted vanes...depending on engine, might be 13-15 'stages' of compression.
Air (hot air, now) is 'tapped' off from one or two of those stages, and sent to the ACM (air-cycle machine), which is a fancy name for an air
conditioner...the compressed air is routed to a turbine, where it expands, and cools. Ambient air is also scooped up, but it mostly provides cooling
for the air/heat exchanger...this is a step that the hot, compressed air goes thru before getting to the turbine, so you can get maximum cooling from
the expansion.
The air from the turbine is controlled to reach the rest of the downstream at a temperature of about 34 or 35 degrees F, to prevent ice formation.
THEN, of course, more hot air can be mixed in then to bring the resulting air to a comfortable temp before entering the cabin.
So, if there are 'toxins' that magically float aloft, then they are being presented to airline passengers...maybe THAT is the conspiracy!
Seriously, finely atomized particles at high altitudes tend to disperse, and are diluted due to high upper-level winds, and thermal currents. Toxins
may reach the Earth's surface via a phenomenon dubbed 'acid rain'...ever heard of that??
