Sounds like some post-apocalyptic menu item... but for years now a few of us have had one of the MAIN reasons for chemtrails down as either: - An early warning 'radar' type system for UFOs - An EM type plasma that can interrupt some UFO movement - As above but provides the conditions to amplify D.E.W. type technology aimed at downing craft.  Here's a recent article:

   We are dealing with Star Wars. It involves the combination
   of  chemtrails for creating an atmosphere that will support  electromagnetic
   waves, ground-based, electromagnetic field  oscillators called gyrotrons,
   and ionospheric heaters. Particulates  make directed energy weapons work
   better. It has to do with "steady  state" and particle density
   for plasma beam propagation.
   They spray barium powders and let it photo-ionize from
   the  ultraviolet light of the sun. Then, they make an aluminum-plasma
   generated by "zapping" the metal cations that are in the spray
   with  either electromagnetics from HAARP, the gyrotron system on the ground
    [Ground Wave Emergency Network], or space-based lasers. The barium  makes
   the aluminum-plasma more particulate dense. This means they can  make a
   denser plasma than they normally could from just ionizing the  atmosphere
   or the air.
   More density [more particles] means that these particles
   which are  colliding into each other will become more charged because there
   are  more of them present to collide. What are they ultimately trying to
    do up there -- is create charged-particle, plasma beam weapons.    Chemtrails are the medium - GWEN pulse radars, the various
   HAARPs,  and space-based lasers are the method, or more simply:
   Chemtrails are the medium -- directed energy is the method.
   Spray and Zap.
   This system appears to be in Russia, Canada, the United
   States, and  all of Europe. Exotic weapons can be mobile, stationary, land-based,
    aerial, or satellite.
   It is an offensive and defensive system against EM attacks
   and  missiles. It uses ionospheric particle shells as defense mechanisms
    [like a bug-zapper shell]* against missiles and EM attacks. That  means
   they spray and then pump up the spray with electromagnetics.  When these
   shells are created using the oscillating, electromagnetic,  gyrotron stations,
   it "excludes" and displaces the background  magnetic field. These
   shells can be layered one above another in a  canopy fashion for extra
   protection from missiles. The chemtrail  sprays have various elements in
   them like carbon which can used to  absorb microwaves. Some of these sprays
   have metal flakes in them  that make aerial craft invisible to radar. Spoofer
   sprays. Sprays  like these can be used to create colorful, magnetized plasmas
   to  cloak fighter jets.
   There are satellite weapons involved. Activists are using
   meters and  are getting readings of microwaves, x-rays, and some other
   kind of  emission that they are not sure of, maybe a low-intensity laser.
   They are also photographing gas plasma generation due
   to the heating  of chemtrails by electromagnetics. The technical names
   for vertical  and horizontal plasma columns are columnar focal lenses and
    horizontal drift plasma antennas. Various size of gas plasma orbs are
    associated with this technology. These orbs can be used as  transmitters
   and receivers because they have great, refractory and  optical properties.
   They also are capable of transmitting digital or  analog sound. Barium,
   in fact, is very refractive -- more refractive  than glass.
   What does that mean? Someone or someones are very involved
   in  unconstitutional, domestic spying and the entrained plasma orbs  carried
   on electromagnetic beams can be used for mind control  programming. The
   satellites can be programmed to track and monitor  various frequencies
   on different parts of your body. These  electromagnetic beams carrying
   the gas plasma orbs stick due magnetic  polarity and frequency mapping
   and tracking to people's eyes, ears,  temples, and private parts. A beam
   with entrained orbs carries  pictures in each orb just like the different
   frames in a movie. It is  a particle beam that is also a frequency weapon.
   The satellites download holographic mind control movies,
   pictures,  sounds, and sensations to people through this technology. The
   Air  Force has stated in "Air Force 2025" that their goal is
   to develop  virtual and augmented reality mind control. Depending on the
   how the  computer is programmed or depending on the mood or intent of the
    person interfacing with the technology, you can be probed, bothered,
   gaslighted, frightened, manipulated, electronically raped, or  tortured.
   It scans your brain frequencies and deciphers your  thoughts. The satellites
   track you by mapping your bioenergetic  signature [body biometrics] and
   constantly scanning an area to find you.
   We are the lab rats for this technology and something
   is very wrong  in the military or intelligence branches somewhere. Because
    developmental projects in government and military are often so  compartmentalized,
   I suppose someone could be using and developing  this technology secretly
   and without authorization. Then again,  behavioral and mind control programs
   were an authorized policy under  MKULTRA. Our country has a history of
   experimenting on its citizens.  We are talking about satellite charged-particle
   frequency weapons  attacking a person 24 hours a day. Psychotronic weapons
   are  considered weapons of mass destruction by the U.N.
   "HAARPs" can create earthquakes and can also
   x-ray the earth to find  underground military bases, gold, or oil reserves.
   These ionospheric  heaters can also operate as an over-the-horizon or under-the-ocean
    communications system. This system can control the weather or create
   disasters. Taken together with the aurora keyhole through-your-roof  satellite
   surveillance system, Echelon electronic computer/phone  sweeps, plasma-cloaked
   DOD Drug War helicopters and stealths,  implants, and cameras on the street,
   it constitutes one, big global  and space control grid.
   These weapons involve beams. Two beams overlapped will
   couple into a  particle-ion beam that will bounce off of a remote target
   and send a  holographic image back to the satellite for remote spying operations.
    When you cross two strong beams, you can supposedly* create scalar  energies.
   These energies can be used as untraceable weapons for  nuclear size explosions
   or for defense. These crossed-energies can be  used to cause a person's
   physical electrical system to fail or with a  lower frequency, administer
   a kind of remote electro-shock. Visualize  touching a positive and negative
   electric cable to each other on top  of your head. Scalar energies can
   be utilized in hand-held military  guns and on tanks. They can dud-out
   electronics or cause large,  electrical blackouts. Scalar energies are
   practically impossible to  shield against. You need lead, ceramics, and
   a deep underground  facility to not be affected by these weapons. Or, you
   need to be up  and above the field of battle.
   People who are working on these issues hear tones and
   hums. If you  hear persistent tones and static; have body vibrations, burning
    sensations, "bangs" to the head, neurological damage, or immune
    system damage; are hearing electronic voices or hearing the sound of
   a plasma; suffering from pains deep in your organs or constant  headaches;
   or experiencing other anomalous activity then you may be  being targeted
   by directed energy, mind control weapons. These  weapons could be on helicopters,
   jets, stealth fighters, or on  satellites. Directed energy beams and electromagnetic
   waves can be  sent to you via hand-held devices or piggy-backed in on cell
   phone  and satellite towers.
   Is it possible that someone(s) are very afraid of coming
   famines and  riots due to the ongoing, man-induced failure of the ecological
    system, and they are saturating the earth with chemtrails for large- scale,
   gas plasma mind control? Is this the last grasp for the  world's resources?
   Or, are they just control freaks and money  mongers? Someone would like
   to get to that oil under the melting [due  to chemtrail-trapped EM heat]
   Artic. And, I guess the Third World is  not a part of this system. I don't
   think that the developed nations  are going to let them in on this either.
   Any country that joins this NATO system will become mind-controlled
    and diseased due to the associated, intense, oscillating,  electromagnetic
   fields, electromagnetic soup, and the poisonous,  toxic chemtrails. Our
   DNA will break. We risk the earth's spin and  tilt becoming messed up due
   to mucking around with the magnetic  fields through this military technology.
   Maybe, it is already messed up.
   It constitutes U.S. global domination via NATO and the
   erosion of  civil rights. According to Charlotte Iserbyt and Al Martin,
   there are  ex-KGB and ex-STASI advising our new Office of Total Information
    Awareness. They are the ones creating our new internal passports  [national
   ID]. And under "The Treaty on Open Skies," we have  overflights
   by Russian and German military. Who exactly is flying  those plasma-cloaked
   craft that are seen all over this country and  mistaken for UFOs by people
   who do not know about this aerial  deception technology? Obviously, we
   have another "Project Paperclip"  in the making. We can add the
   new thugs to the 2,000 Iraqi brought  into country by Daddy Bush who are
   now living in Nebraska.
   The elitist corporate government is going to hold the
   rest of us  hostage with directed energy weapons in space, if the Policy
   for a  New American Century group - PNAC - Bush and cronie think tank has
    their way, along with directed energy attacks against any country or
   citizen that they decide they do not like. These weapons can create  climate
   war, weather war, mind war, cyber war, disease war, disaster  war, and
   undetectable war. Taken together they can create economic war.
   If this system is not stopped, it will kill billions
   due to aluminum  and barium poisoning. It will kill billions due to crop
   failures and  world-wide famine. It will cause heart attacks, strokes,
   and cancers.  It will cause stillbirths, miscarriages, and infertility.
   The  chemtrail sprays often have fungi, bacteria, viruses, dessicated red
    blood cells, crystalline substances, carbon, metal cations, lithium,
   other chemicals, heavy metals, and God knows what - probably smart  dust,
   or nanocrap. Years of biowarfare testing on the American public  is no
   big secret anymore. Spraying germs in the sky where they mutate  due to
   the ultra-violet light -- brillant plan, my man. Are we  acceptable losses
   or is this by design?
   I know that many of the major players have big investments
   in  pharmaceutical companies, GM seeds [seeds that can grow in an  electromagnetic
   soup], weapons and directed energy development  contracts, oil contracts,
   genetic research, and mind control  research. Some of these people have
   had a familial history of  financial and policy support for population
   control, eugenics,  Hitler, Mao, Stalin, Lenin, Marx, Pinochet, Hussein,
   and various  other dictators. Some of the major players were the masterminds
   of  the death squads in Central and South America. They stand to make a
    big profit on our death and disease. Just take a look at Rumsfield  and
   Tamiflu.
   I assume that they know the dangers of this system and
   that they take  care to stay in their shielded, air-filtered offices, homes,
   bases,  and cars. I assume they take chelating substances to remove the
    barium and aluminum from their bodies and minds. If not, then they  really
   do not understand the far-ranging implications of this  destructive system.
   Congress may not understand just what a terrible  weapons system and control
   grid they are funding.
   As I understand it, Tesla towers attached to deep-earth,
   free-energy  taps are to be created over the 10-12 magnetic poles and the
   GWEN  system phased-out. Has this already been done? This should allow
    total control of the earth through giant, Tesla death ray-guns. This
   natural, electromagnetic earth was not meant to be an un-natural  dynamo
   to power man's weapons or his utility companies.
   Over-unity systems [Tesla devices]* are as of yet, another
   unexplored  and probably not understood man-made energy. We should be very
    suspect of free energy. As we can see, the forms of man-made energy  that
   have been created and used in the past have not been good for  this planet.
   Maybe it is time to reconsider the options available to  us through the
   development of crops for fuel, wind, solar, and water  power. We need world-wide,
   different, more holistic, renewable,  energy programs.
   Is there any good news? Yes. There has been tons of particulate
    dumping through the spray operations for 8 years over the Americas,  Europe,
   Scandinavia, Eastern Europe, and from what I can find out,  over Russia.
   And, what goes around blows around, right? So, these  substances are probably
   actually global. It sure makes a ton of sense  to spray poisonous elements
   in 24 NATO countries and let the  substances be carried around the earth
   on the jet streams to poison  yourself, your enemies, and all neutral and
   non-combatent countries.  Talk about making more enemies.
   The water, air, and soil of all of these countries is
   so saturated  with metal cations that these weapons freaks should be able
   to zap  and mind f--k each other quite well now and as often as they wish.
    Once they have clobbered each other with light-saber beams for a few
   years and razed and scorched sections of the earth, they may start to
   realize that this foreign policy will lead to a defective human race  and
   a rotten economy.
   Do you think they will have knocked some sense into each
   other by  then and will decide that non-proliferation and arms reduction
   is the  more civilized and mature direction to take in world affairs? I
   doubt  it, cause only idiots would have developed horrific, planet-killer
    weapons like these. But, I'll bet the rest of the planet will finally
    rise up and tell these juvenile delinquents to quit playing with  those
   rayguns right this second.
   After further thought on Bearden + -- a big over-unity
   and free  energy proponent of Tesla technology that makes energy off of
   boiling  the ionosphere or stealing electricity from the mis-named "vacumn"
    called Life, I have decided that Bearden is telling us some, if not  most,
   of the truth. Same for Eastlund.
