Chemtrails Proven By FAA Data. Bleed Air HEPA Filters Loaded With Particulates.

I have been saying for years that contrails cannot form into clouds without introduction of particulates for the water vapor to condensate to. This is how clouds form. The water vapor coalesces to dust or salt, or injected particulates into the atmosphere. This is how cloud seeding works.

For decades, a very fine particulate has been used in cloud seeding, Silver Iodide.

This substance creates trillions of particulate per gram when burned, little tiny microscopic particles of metallic dust. 

Now, if this dust is being used in Chemtrails, it should show up in the HEPA filters of commercial aircraft bleed air systems, which supply ambient air into the cabin through the pre full compressor stage of the engines. Well guess what. These are loaded with particulates.

Spengler et al. (2012) measured airborne UFPs, which the authors defined as particles measuring in diameter from 6 nanometers to 0.3 µm, aboard 55 flights under routine operating conditions. Concentrations were reported as 15-minute average numbers of particles per cubic centimeter of air (p/ cm3 ).

Maximum concentrations from all flights ranged from 1 to 312,000 p/cm3 . Particle concentrations from 500 to 10,000 p/cm3 indicated minor events, and concentrations greater than 10,000 p/cm3 indicated major events.

So, there were events that they reported up to 312,000 p/cm3?? This is 30 times higher than the threshold for a major event. Did this concern the FAA? Apperently so, because a public law was enacted to try and clean up the cabin air..

Sec. 917. Research and development of equipment to clean and monitor the 
           engine and APU bleed air supplied on pressurized aircraft.

Much work is needed to carry out the directives of the Public Law 112-95 (2012). This work includes:

• the ongoing study of air quality in aircraft cabins through a comprehensive sampling program for broad characterization and evaluation of the constituents of contaminated bleed air;

• assessment of bleed air quality on the full range of commercial aircraft operating in the U.S.;

• continued assessment of health risks to passengers who may be exposed during bleed air events;

• continued development of instrumentation for sensing bleed air and cleaning contaminated air in pressurized aircraft cockpits and cabins;

• continued development and evaluation of current measurement technologies both on the ground and in flight; and

• development of a systematic reporting standard for contaminated bleed air events.
