− | Neither is there any evidence for chemtrails nor are their proponents able to produce such. Quite a number of logical reasons contradict their possible existence. Condensation trails are a well reviewed phenomenon and technical articles on this date back to the 1940ies. Already NACA, the precesessor of NASA, examined this phenomenon due to its military relevance for locating aircrafts in WWII. In a document dated 1942 (decades prior to chemtrail hypotheses) NACA researchers named the meteorological circumstances responsible for ''persistent contrails''. So far no evidence of the existence of aluminum or barium in condensation trails or aircraft fuels has been given. The Deutsche Flugsicherung GmbH (German Air Traffic control) confirmed they did not observe any conspicuous or remarkable air activity which could be associated with the circumstance described in „Raum & Zeit". The Deutsche Wetterdienst (German Meteorological Service) informed their data do not show any peculiarities indicating any irregular forms of condensation trails. | + | Neither is there any evidence for chemtrails nor are their proponents able to produce such.

− | The Bundesministerium der Verteidigung (German Federal Ministry of Defence) also has no further information. The headquarters of the US-Air Force Europe informed that the projects as described do not and did not exist. Greenpeace as well as the Umweltbundesamt (UBA, German Federal Environment Agency) regard the chemtrail theory as dubious. The UBA even inquired with the World Health Organization (WHO) about an alleged risk analysis on potential consequences of chemtrails supposedly conducted by WHO. WHO assured they neither had knew of chemtrails nor had they done any study on the subject. The phenomena described are also unknown to Deutsches Zentrum für Luft- und Raumfahrt (DLR, German Aerospace Center). Since many years, DLR's Institute of Atmosphere Physics examines the effects of air traffic emissions on the atmosphere, including numerous measurements of gas and particle emissions of commercial aircrafts. Neither is the German Meteorological Service able to detect anomalies in their data indicating special ''chemtrail'' forms in condensation trails. The German federal government also commented on chemtrails in 2004: Excerpt from a reply (reference: Deutscher Bundestag Drucksache 15/3694<ref>http://dipbt.bundestag.de/dip21/btd/15/036/1503694.pdf</ref>) of the Federal Government given to Herbert Frankenhauser (member of parliament, party: CSU): [...]Question: ''Are so-called chemtrails (chemical traces sprayed by aircrafts) released to research the reduction of global warming over the territory of the Federal Republic of Germany?
