Supporters of the 1990ies chemtrail hypothesis believe certain substances - which are not described in detail - were mixed with kerosene in order to create an effect on the global climate, especially on the greenhouse effect. Other conspiracy theorists believe it is part of a world wide program to reduce the global population, or for birth or even mind control. Behind these programs were, according to the chemtrail groups, the [[Freemasonry|Freemasons]], the [[Illuminati]] or an alleged Jewish conspiracy. There are often ties to extremist right groups, "brown [[esotericism]]" and supporters of [[cloudbuster]], [[colloidal silver]] and [[Zapper|zappers]] according to [[Hulda Clark]]. Typical supporters of the chemtrail hypothesis are Georg Ritschl, Werner Altnickel, Peter Platte, Helmut Gobsch, Heinz Gerhard Vogelsang, [[Don Croft]] and [[Rosalie Bertell]]. In Germany, extreme right political party NPD started an inquiry of ''chemtrails'' in the parliament of the federal state of Saxony. The issue of chemtrails is often used as a catchword by the extremist right.

These fallacious and unsupported assumptions are often promoted in the esoteric Swiss magazine "Zeitenschrift"<ref>Zeitenschrift issue 49, 2006</ref>, in "Neue Impulse Treff" network associated with [[Scientology]], and by the esoteric libertarian association "live Net Concept 2010". A popular photographic "proof" of alleged chemtrail operations can be seen in the picture on the right: A modified Boeing NKC-135A Stratotanker (717-100), serial number 17244, stationed at Edwards AFB in California.<ref>http://www.airliners.net/search/photo.search?cnsearch=17244&distinct_entry=true</ref> It sprays water to test the flight quality of planes under icing conditions. Tests are done on various kinds of planes, such as fighter jets<ref>[http://www.af.mil/shared/media/photodb/photos/040213-F-9999M-002.jpg USAF picture of icing experiment on a fighter jet]</ref> or a Embraer EMB-120RT.<ref>http://aircrafticing.grc.nasa.gov/courses/inflight_icing/resources/pdf/monroe_accident_report.pdf</ref> This particular test plane has been decommissioned meanwhile.

Chemtrail supporters frequently claim that so called low budget airlines, especially Irish Ryanair, were only able to offer flights at such low prices because their main job kept in reality was the creation of chemtrails.
