If jet fuel is ruled-out as culprit in “chemtrails”, the only remaining point of chemical injection is inside the bypass duct. See explanation:
This is an except of Mr Meiring’s video taken from a window of the Lufthansa 747-8 Jumbo jet. We see the exhaust coming directly out of the engines as they pass by the window.

Jörg Meiring: “Today I got a shock. However, here I am describing another side of the company policy of a mad German devil company.
The whole flight was a single torture. We were trapped in a Jumbo Boeing 747-8 in the smallest chairs of the 4th class, as it does not exist in other airlines. Lufthansa has four long-range human rights categories: 1. First Class, 2. Business Class, 3. Premium Economy Class and 4. Economy Class. The premium economy class corresponds to the second class of the other airlines. So if you are looking for a flight, you have to know that, especially on an 11-hour flight, as I had it. The flight is the purest ordeal for the body, and I do not understand how people get soaked in such a minisitz without leg room and without footboard … I felt like raped! Yes, I felt like I was being raped by the Lufthansa because I did not know it before! But now comes the real thing I am about:
In the past 5 years, I have always identified chemtrail-sprayed airplanes with flightradar24.com. Because I have now understood how the “world” works, I do not do this regularly for a year, but use the time better and read in the Bible to understand the world better. I noticed earlier that Lufthansa, Air Berlin and Condor (at least until a year ago) did not spray. I knew until then, but also that it could be because the here in Germany only so many short circuits fly. So I always thought that these companies are immune to Satan.
TODAY I saw with my own eyes the spray directly from a Lufthansa plane. In the last few weeks, the flight has been passing over Africa and not over the sea. The route across Africa then leads across the Mediterranean. There, to my shock, the chemtrails were sprayed, until half an hour before the landing in Frankfurt. I estimate the amount of output on one to two tons of material. This is the first time Italy, Greece and Turkey are attacked, because here, as with us, the wind blows. Take a look at the video I made from a few small people, who have been working with “music” (Youtube video editor). One can see here, which I have always suspected, that the material inside the turbine is turbulent and is not diverted separately as before. In this film you can see only the outer turbine because of the much too small windows.”
But do not be afraid, because God says it must be so … Halleluja”

Heute habe ich einen Schock bekommen. Jedoch beschreibe ich hier erst eine andere Seite der Firmenpolitik einer wahnsinnigen deutschen Teufelsfirma.
Der ganze Flug war eine einzige Tortur. Wir wurden in einem Jumbo Boeing 747-8 eingepfercht in kleinste Stühle der 4. Klasse, wie es diese nicht in anderen Fluggesellschaften gibt. Lufthansa hat 4 Menschenrechtsklassen in der Langstrecke: 1. First Class, 2. Business Class, 3. Premium Economy Class und 4. Economy Class. Die Premium Economy Class entspricht der 2. Klasse der anderen Fluggesellschaften. Wenn man sich also einen Flug sucht, dann muss man das unbedingt wissen, besonders auf einem 11-stündigem Flug, wie ich es hatte. Der Flug was die reinste Tortur für den Körper, und ich verstehe nicht, wie Menschen sich in so einem Minisitz ohne Beinfreiheit und ohne Fußablage reinquetschen lassen… ICH fühlte mich wie vergewaltigt! Ja, ich fühlte mich von der Lufthansa verarscht und vergewaltigt weil ich das nicht vorher wusste! Aber jetzt kommt das eigentliche worum es mir geht:
In den letzten 5 Jahren identifizierte ich Chemtrail-sprühene Flugzeuge immer mit flightradar24.com. Weil ich zwischenzeitlich verstanden habe wie die “Welt” funktioniert, tue ich das seit einem Jahr nicht mehr regelmäßig sondern nutze die Zeit besser und lese in der Bibel um die Welt besser zu verstehen. Mir fiel früher auf, dass Lufthansa, Air Berlin und Condor (jedenfalls bis vor einem Jahr) NICHT sprühten. Ich wusste bis dahin aber auch, dass es daran liegen könnte, weil die hier in Deutschland nur so viele Kurzstrecken fliegen. Ich dachte also immer, dass diese Firmen immun gegen Satan sind.
HEUTE sah ich selbst mit meinen eigenen Augen die Sprühung direkt aus einem Flugzeug der Lufthansa. Der Flug verläuft in den letzten Wochen auch neuerdings über Afrika und nicht mehr daneben über dem Meer vorbei. Die Route über Afrika führt dann mittig über das Mittelmeer. Dort wurden zu meinem Erschrecken die Chemtrails ausgesprüht, und zwar bis eine halbe Stunde vor der Landung in Frankfurt. Ich schätze die Menge der Ausgabe auf ein bis zwei Tonnen Material. Damit wird jetzt erstmals auch Italien, Griechenland und Türkei angegriffen, denn es weht auch hier, wie bei uns, der Westwind. Seht euch das Video an, das ich aus einigen kleinen zusammengestellt habe und mit “Musik” untermalt habe (Youtube-Videoeditor). Man sieht hier, was ich schon immer ahnte, dass das Material innerhalb der Turbine verwirbelt wird und nicht separat ausgeleitet wird wie früher. In diesem Film sieht man leider nur die äußere Turbine wegen der viel zu kleinen Fenster.
Aber habt keine Angst, denn Gott sagt, es muss so sein… Halleluja
EPA Employee Fired for Exposing Dangerous Aluminum Contamination From Aircraft Emissions Fallout.
Disclaimer: Many researchers disagree with Wigington’s apparent support for the corrupt UN/IPCC agenda to blame CO2 and GHG emissions for global warming. While emphatic to indict government agencies for providing lies and coverups for covert geoengineering, Wigington inexplicably singles out the vast UN/IPCC criminal network to present trustworthy “climate change” data despite it’s repeated history of climate-gate scandals and failed prediction models. Wigington’s troublesome cognitive disonance appears as an attempt to throw a bone of financial support to his connections in the network of solar energy providers and to those who write policy for alternative energy legislation. Despite his glaring double-speak, Wigington provides related information and world view that is worthwhile in connecting the dots of mass deception.
Much has already transpired since Donald Trump took office, and road signs do not bode well in regard to the direction we are headed. Should this be a surprise? More than ever before the power structure is trying desperately to hide reality from a population that is largely uninterested in the bigger picture in the first place. More than ever, those in power are doing their best to completely eliminate any remaining restraints on the military/industrial/banking complex. Will the last remaining remnants of the planet’s life support systems (that are still functioning) be looted, plundered, and pillaged in order to keep business as usual till the last possible moment? Environmental and societal collapse will be blindingly swift. What is the current state of our oceans? US government officials declare fisheries disaster for the entire west coast of North America.
The satellite photo above was captured at 11 pm Pacific time on 2/1/17. This is a shocking example of radio frequency/microwave transmissions manipulating a square cloud perimeter around an extensive circular low pressure circulation.
On the other side of the world, in the Bay of Bengal, another fisheries collapse is unfolding. The global refugee crisis from collapsing ecosystems will soon “fuel an unimaginable refugee crisis” according to a new military analyst report. The city of Miami Beach is going to spend half a billion dollars ($500,000,000) to temporarily keep a few neighborhoods from being inundated from rapidly rising seas. Coastline cities all over the globe face the same fate, the efforts to mitigate this process is futile. Total nuclear fuel rod meltdowns at Fukushima are confirmed, and the world’s top scientists have advanced the hands of the “Doomsday Clock” to an alarming 150 seconds to “midnight”. Will the masses be awakened to our collective peril before the sand in the hourglass runs out? The latest installment of Global Alert News is below.
Many choose not to stand up and make their voice heard in the battle for the greater good unless or until someone somewhere can give them a guarantee of certain success, this scenario must change. Life gives no such guarantees, ever. No matter how daunting the odds, we must make the decision to do what is right, because it is right. We are free falling into the most defining and critical chapter of our species, indeed, of life on Earth. How can we know what difference we may have made unless or until we are willing to stand and be counted in the critical effort to fully expose the untainted truth on countless fronts? We must take a stand today, if we are to salvage any tomorrow.

Beyond the Veil excerpt with host Raphael O’Neil interviews Captain “G” of US Army 104 transportation Division who reports he was ordered to deliver 5,000 body bags to New Orleans, 11 days prior to Katrina making landfall.
NOTE: Captain G’s report is a bit confusing since Katrina was not a named storm until August 23rd, only 6 days before landfall in southeast Louisiana on August 29th. If the captain’s timeline of foreknowledge is correct, Katrina was only in a planning stage and only hypothetically listed as the next named storm eleven days prior to landfall. (Katrina History)

GOES Satellite time-lapse reveals weaponization of Katrina as aircraft spray aerosols to intensify the Hurricane.
Technology to mitigate or intensify Hurricanes using aerosols is documented in the Hurricane Aerosols Microphysics Program (HAMP). Carbon Black aerosols are known to increase hurricane strength when aircraft spray is directed toward the center of circulation. Satellite images reveal obvious aerosol engineering of Hurricane Katrina as it enters the Gulf of Mexico. Hurricanes as weapons are an operation of domestic terrorists who have control of the US government and have nothing to do with Russian weather control. (More on HAMP)
The government’s failure to prepare for a major hurricane like Katrina reminds us of the government’s failure in the 9/11 false flag. The similarities that point to Katrina as an operation of deliberate destruction is unavoidable. Salon Magazine: Timeline to disaster – Salon’s hour-by-hour account of the worst natural disaster in U.S. history — and how our government failed.
“Every level of government failed, to one degree or another, in the aftermath of Katrina. But the lion’s share of the blame must go to the highest level, the one that has ultimate responsibility: the federal government.” (George W. Bush) – Timeline to Disaster (PDF)
Hurricane Katrina was the deadliest and most destructive Atlantic tropical cyclone of the 2005 Atlantic hurricane season. It was the costliest natural disaster, as well as one of the five deadliest hurricanes, in the history of the United States. Among recorded Atlantic hurricanes, it was the sixth strongest overall. At least 1,833 people died in the hurricane and subsequent floods, making it the deadliest U.S. hurricane since the 1928 Okeechobee hurricane; total property damage was estimated at $81 billion (2005 USD), nearly triple the damage brought by Hurricane Andrew in 1992.
Hurricane Katrina formed over the Bahamas on August 23, 2005 and crossed southern Florida as a moderate Category 1 hurricane, causing some deaths and flooding there before strengthening rapidly in the Gulf of Mexico. The hurricane strengthened to a Category 5 hurricane over the warm Gulf water, but weakened before making its second landfall as a Category 3 hurricane on the morning of Monday, August 29 in southeast Louisiana. It caused severe destruction along the Gulf coast from central Florida to Texas, much of it due to the storm surge.
The most significant number of deaths occurred in New Orleans, Louisiana, which flooded as the levee system catastrophically failed, in many cases hours after the storm had moved inland. Eventually 80% of the city and large tracts of neighboring parishes became flooded, and the floodwaters lingered for weeks. However, the worst property damage occurred in coastal areas, such as all Mississippi beachfront towns, which were flooded over 90% in hours, as boats and casino barges rammed buildings, pushing cars and houses inland, with waters reaching 6–12 miles (10–19 km) from the beach.
The hurricane surge protection failures in New Orleans are considered the worst civil engineering disaster in U.S. history and prompted a lawsuit against the U.S. Army Corps of Engineers (USACE), the designers and builders of the levee system as mandated by the Flood Control Act of 1965. Responsibility for the failures and flooding was laid squarely on the Army Corps in January 2008 by Judge Stanwood Duval, U.S. District Court, but the federal agency could not be held financially liable due to sovereign immunity in the Flood Control Act of 1928. There was also an investigation of the responses from federal, state and local governments, resulting in the resignation of Federal Emergency Management Agency (FEMA) director Michael D. Brown, and of New Orleans Police Department (NOPD) Superintendent Eddie Compass.
Several agencies including the United States Coast Guard (USCG), National Hurricane Center (NHC), and National Weather Service (NWS) were commended for their actions. They provided accurate hurricane weather tracking forecasts with sufficient lead time.

Piezoelectric Clouds and Aerosols Link to Drought and Cratastrophic Floods
Sat24.com is the European weather satellite service that provides medium resolution imaging loops in the visible and infrared spectrum.
This short video will focus on the issue of artificial aerosol clouds that express a piezoelectric characteristic based on applied radio frequency energy from fixed-based transmitters.
The variation in the distance between the aerosol cloud waves is a result of the frequency of the energy applied.
Notice how the waves remain stationary over a geographic area while the aerosols flow past them, from left to right.
This indicates that the transmitters are in a fixed location and intended to polarize the aerosols that act as cloud condensation nuclei.
Moisture within this layer can either be trapped to produce drought or later reverse-polarized to cause floods.
This technology allows eco-terrorists the ability to create a water bomb by withholding rain until it is released over a city or region targeted for a catastrophic flooding.
The Piezoelectric Effect is the ability of certain materials, like Barium Titinate to either:
1) generate an electric charge in response to externally applied mechanical pressure.
2) generate pressure by application of an external electric charge.
A fixed-based transmitter capable of focusing pulses of electrical energy into the barium-laced artificial clouds could, therefor, produce heat through rapid and alternating expansion and collapse of Barium Titanate.
Warming of the artificial cloud layer in this way could act to inhibit condensation in addition to the super-saturation of CCN already provided by the aerosols, themselves.
During World War II, researchers discovered a new class of man-made materials, called ferroelectrics, which exhibited piezoelectric constants many times higher than natural piezoelectric materials such as quartz. One of these was developed is barium titanate.
Barium – along with aluminum – has been found in rainwater samples related to aircraft contrail emissions suspected of containing aerosols of barium, aluminum and other environmental pollutants.
The Piezoelectric Effect (Source)
What is the Piezoelectric Effect?
Piezoelectric Effect is the ability of certain materials to generate an electric charge in response to applied mechanical stress. The word Piezoelectric is derived from the Greek piezein, which means to squeeze or press, and piezo, which is Greek for “push”.
One of the unique characteristics of the piezoelectric effect is that it is reversible, meaning that materials exhibiting the direct piezoelectric effect (the generation of electricity when stress is applied) also exhibit the converse piezoelectric effect (the generation of stress when an electric field is applied).
When piezoelectric material is placed under mechanical stress, a shifting of the positive and negative charge centers in the material takes place, which then results in an external electrical field. When reversed, an outer electrical field either stretches or compresses the piezoelectric material.
The piezoelectric effect is very useful within many applications that involve the production and detection of sound, generation of high voltages, electronic frequency generation, microbalances, and ultra fine focusing of optical assemblies. It is also the basis of a number of scientific instrumental techniques with atomic resolution, such as scanning probe microscopes (STM, AFM, etc). The piezoelectric effect also has its use in more mundane applications as well, such as acting as the ignition source for cigarette lighters.
The History of the Piezoelectric Effect
The direct piezoelectric effect was first seen in 1880, and was initiated by the brothers Pierre and Jacques Curie. By combining their knowledge of pyroelectricity with their understanding of crystal structures and behavior, the Curie brothers demonstrated the first piezoelectric effect by using crystals of tourmaline, quartz, topaz, cane sugar, and Rochelle salt. Their initial demonstration showed that quartz and Rochelle salt exhibited the most piezoelectricity ability at the time.
Over the next few decades, piezoelectricity remained in the laboratory, something to be experimented on as more work was undertaken to explore the great potential of the piezoelectric effect. The breakout of World War I marked the introduction of the first practical application for piezoelectric devices, which was the sonar device. This initial use of piezoelectricity in sonar created intense international developmental interest in piezoelectric devices. Over the next few decades, new piezoelectric materials and new applications for those materials were explored and developed.
During World War II, research groups in the US, Russia and Japan discovered a new class of man-made materials, called ferroelectrics, which exhibited piezoelectric constants many times higher than natural piezoelectric materials. Although quartz crystals were the first commercially exploited piezoelectric material and still used in sonar detection applications, scientists kept searching for higher performance materials. This intense research resulted in the development of barium titanate and lead zirconate titanate, two materials that had very specific properties suitable for particular applications.
There are many materials, both natural and man-made, that exhibit a range of piezoelectric effects. Some naturally piezoelectric occurring materials include Berlinite (structurally identical to quartz), cane sugar, quartz, Rochelle salt, topaz, tourmaline, and bone (dry bone exhibits some piezoelectric properties due to the apatite crystals, and the piezoelectric effect is generally thought to act as a biological force sensor). An example of man-made piezoelectric materials includes barium titanate and lead zirconate titanate.
In recent years, due to the growing environmental concern regarding toxicity in lead-containing devices and the RoHS directive followed within the European Union, there has been a push to develop lead free piezoelectric materials. To date, this initiative to develop new lead-free piezoelectric materials has resulted in a variety of new piezoelectric materials which are more environmentally safe.
Applications Best Suited for the Piezoelectric Effect
Due to the intrinsic characteristics of piezoelectric materials, there are numerous applications
that benefit from their use:
High Voltage and Power Sources
An example of applications in this area is the electric cigarette lighter, where pressing a button causes a spring-loaded hammer to hit a piezoelectric crystal, thereby producing a sufficiently high voltage that electric current flows across a small spark gap, heating and igniting the gas. Most types of gas burners and ranges have a built-in piezo based injection systems.
The principle of operation of a piezoelectric sensor is that a physical dimension, transformed into a force, acts on two opposing faces of the sensing element. The detection of pressure variations in the form of sound is the most common sensor application, which is seen in piezoelectric microphones and piezoelectric pickups for electrically amplified guitars. Piezoelectric sensors in particular are used with high frequency sound in ultrasonic transducers for medical imaging and industrial nondestructive testing.
Because very high voltages correspond to only tiny changes in the width of the crystal, this crystal width can be manipulated with better-than-micrometer precision, making piezo crystals an important tool for positioning objects with extreme accuracy, making them perfect for use in motors, such as the various motor series offered by Nanomotion.
Regarding piezoelectric motors, the piezoelectric element receives an electrical pulse, and then applies directional force to an opposing ceramic plate, causing it to move in the desired direction. Motion is generated when the piezoelectric element moves against a static platform (such as ceramic strips).
The characteristics of piezoelectric materials provided the perfect technology upon which Nanomotion developed our various lines of unique piezoelectric motors. Using patented piezoelectric technology, Nanomotion has designed various series of motors ranging in size from a single element (providing 0.4Kg of force) to an eight element motor (providing 3.2Kg of force). Nanomotion motors are capable of driving both linear and rotary stages, and have a wide dynamic range of speed, from several microns per second to 250mm/sec and can easily mount to traditional low friction stages or other devices. The operating characteristics of Nanomotion’s motors provide inherent braking and the ability to eliminate servo dither when in a static position.

An Idealized Example. As a specific example, consider a thin disk with radius ∼5 μm and thickness 50 nm composed of three layers: 5 nm aluminum oxide, 30 nm of metallic aluminum, and finally 15 nm of barium titanate (Fig. 1C). The thickness of the Al layer is chosen so that it has high solar-band reflectivity.
“Silica-alumina ceramic hollow microspheres with diameters of 1 μm (e.g., 3M Zeeospheres) can be purchased in bulk at costs less than $0.3/kg. Moreover, bulk vapor-phase deposition methods exist to produce monolayer coatings on fine particles, and there are rapid advances in self-assembly of nanostructures that might be applicable to bulk production of engineered aerosols.”
